One of the highly-rated glue brands in the market is the Loctite brand, which comprises a variety of glue products.Amongst these numerous Loctite products, none seem to beat the Loctite 242 and the Loctite 243, especially in mechanical tasks.
This is because both thread lockers hence provide a perfect adhesive for mechanical work.Looking at them without using them, one would think that the two are the same and that the only difference is in their product name.
Luckily, you do not have to go looking any further because, in this article, we avail you with a detailed comparison of the Loctite 242 and Loctite 243 beginning with their similarities before we get to their differences.

Loctite 242 vs 243 -Details Comparison
Even if glues belong to the same brand, they are not always designed to serve the same purpose.
For instance, you could find glue in the Loctite brand that is specifically designed for nail works and another for sticking wood.
This is because both of these glues, as seen at the beginning, are thread lockers hence excellent for mechanic projects.
As a result, the first and perhaps the only similarity between these two glues relates to the purpose they serve.
Irrespective of the few similarities pointed out above, it remains a fact that there are differences between the Loctite 242 and Loctite 243.
These differences are extensively highlighted and explained in the five attributes below:
In case you are wondering, oil tolerance in this specific context refers to the ability of a glue to withstand the presence of oil.
If you work in the mechanics or have been around the area before, you do not need lessons to know how greasy the place is all the time.
That said, most of the items also tend to have some amount of oil on them, which makes sticking them together challenging.
Luckily, the Loctite 242 and Loctite 243 have been designed in a way that they resist the oil. However, there oil tolerance power is not the same.
Previous users of both types of glue, myself included, confirm that Loctite 243 has a higher oil tolerance power compared to the Loctite 242.
As a result, it will get the job done perfectly and more quickly compared to the Loctite 242.
Therefore, if one is to question which of these two glues is better than the other focusing primarily on the oil tolerance factor, then, the Loctite 243 carries the day.
However, the Loctite 242 is still good for glue if you are not dealing with surfaces that have a generous amount of grease or other oil types on them.
The main reason why people purchase glues is because of their sticking ability better described as adhesion. Have you ever wondered why there are many types of glue for different aspects?
For instance, nail glue, fabric glue, mechanic glue, craft glue, just to mention a few? Well, here is the answer.
All these glues have variations in their adhesion, and the nail glue though perfect for nails, becomes useless in the mechanical field.
With that in mind, even the glues in the same category have different adhesion powers, and affirming this as correct is the Loctite 242 and the Loctite 243.
The Loctite 243 again appears superior to the Loctite 242. Championing this is the fact that while compared to the Loctite 242, the Loctite glue 243 forms a more robust bond, which means higher adhesion power.
As a result, the second differentiating factor between these two sets of Loctite glue is the adhesion capability.
With this again, the best glue amongst these two adhesives becomes the Loctite 243, but then again, it depends on the level of bond you want and your patience.
This is because the Loctite 242 also has a strong bond just not as strong as that offered by Loctite 243
Closely related to the first difference is the simplicity factor. Not all glues are simple to use. Some are often complex, and their complexity is a result of many factors. Consider the case of instruction.
For some glues, the guidelines are quite challenging to understand, maybe because of the language used. In others, it is the preparation process that makes the usage of the glue a bit complex.
Luckily, while comparing the Loctite 242 and Loctite 243, the difference in simplicity does not relate to the aspect of instruction but the preparation process.
Ideally, it will require one to dry off the surfaces of the materials for a strong bond to be formed.
In a mechanic step up, grease is a factor that one has to deal with, as initially indicated.
Since the Loctite 243 is more oil tolerant, this means that one will not have even to undergo the process of first drying the surface, which makes it very simple to use.
On the other hand, the Loctite 242 is not oil tolerant as the Loctite 243. As a result, one will require first drying the surfaces they want to stick together, which makes the usage of the glue a bit complex.
As indicated in the previous factor, the Loctite 243 comes ready to use. This means you do not have to wipe the surfaces you intend to stick before using this glue.
You can go ahead and start the glue application regardless of the state of your surfaces.
On the other hand, you must wipe the surfaces you intend to glue and ensure that they are dry before you can use the Loctite 242.
From this, it is apparent that it will take you extra minutes while dealing with the Loctite 242 glue because of the wiping process.
However, you will use less time while working with the Loctite 243.
Therefore, the other difference between the Loctite 242 and Loctite 243 deals with time where Loctite 243 allows the user to spend less time.
Nonetheless, the time difference should not be anything big even when using the Loctite 242 unless you are dealing with many surfaces that are extremely greasy.
The other differentiating factor between the Loctite 242 and Loctite 243 deals with quality. The Loctite 243 seems to be of better quality than the Loctite 243. I mean, unlike the Loctite 242, it has strong adhesive power and is even more tolerant of oil, as seen in the previous points.
Moreover, it is an upgraded version of the Loctite 242.
Therefore, it is only natural that the Loctite 243 is of better quality with regards to functionality when compared to the Loctite 242. Don’t misquote me, though!
With the given quality descriptions above, you should not go ahead to think that the Loctite 242 glue is a low-quality glue.
No! The glue is made of high-quality ingredients and delivers top-notch services. It even lists among the best glues in the industry today.
The thing is that while compared to the Loctite 243 glue, then, the quality appears to be a bit lower. Nonetheless, it will still get your surfaces attached to one another as long as you follow the specific instruction that the glue demands.
Price is a major factor when it comes to purchasing any commodity, and glues are not an exception. This is because, to be sincere, we live in a society whose economic times are wanting, and what one earns differs from what the other makes.
That is why price becomes another factor to consider when differentiating Loctite 242 from Loctite 243.
Even before spilling the beans, you can tell which among the two Loctite types of glue seems to have a higher buying price.
I mean, if a product offers better and upgraded services, there is a likelihood that their prices are bound to be higher. With that in mind, you are correct if you guessed that the Loctite 243 is expensive.
However, this is not something that should scare you and make you reconsider buying the Loctite 243 glue.
Influencing this is the fact that the price, though slightly higher than the price of the Loctite 242 glue, is affordable and within the price range of similar glues offering similar services.
Nonetheless, if you are working on a budget and need an economical but good Loctite glue, then, the Loctite 242 will come in handy. Hence, price is another factor that differentiates the Loctite 242 from the Loctite 243.
Loctite 271 vs 272
Besides the Loctite 242 and 243, the other commonly confused Loctite glue is the Loctite 271 and Loctite 272.
To say the east, the Loctite 271 and 272, in as much as they share some similarities like belonging to high strength thread lockers and having hard cleanup process, they are very distinct.
Their main distinction is seen in their strength capabilities where the Loctite 272 is more powerful than the Loctite 271.
This is because it has a higher heat resistance level and a wider fastening size support. Notably, the Loctite 272 supports a fastener size of 3/8 inches to 1 ½ inches while the Loctite 271 supports a fastener size of 3/8 inches to 1 inch.
Also, the maximum heat supported by Loctite 272 is 450 while that of the Loctite 271 is 300.
On a positive note, the fixture size of Loctite 271 is shorter as it takes around 10 to 20 minutes unlike the Loctite 272 which takes 40 to 60 minutes.
Therefore, if you are looking for something that will give you quality service, it is better to settle for the Loctite 272. However, if you want to handle your project within the shortest time possible, consider the Loctite 271.
1.What are the different grades of Loctite?
There are four different grades of Loctite, namely low strength, high strength, temperature resistant, and wicking Loctite grades explained below:
Loctite 221 & 222- Low Strength
These are low strength thread lockers due to their low viscosity. As a result, they will work well on projects which have a maximum size of M12.
Loctite 270 & 276- High strength
This grade is actually the opposite of the Loctite 221 & 222. Championing this is the fact that it has high viscosity. Hence, it is perfect for high strength thread lockers especially those that need a permanent fix.
Loctite 272 & 278- Temperature resistant
Unlike the previous reviewed grades, the Loctite 272 & 278 is neither of low strength nor of high strength. This is because it has a medium viscosity. However, you it can still work great on some of the high strength thread lockers needing a permanent thread locking.
Loctite 290- Wicking
The last Loctite grade is the Loctite 290. They are often confusing but since they are made using extremely low viscosity then they are suitable for thread lockers that do not require any disassembling.
2.How Do I Use the Loctite Glue?
Based on the above comparison, there are two ways through which you can use the Loctite glue. The use of either of the methods depends on the type of Loctite glue you are using. For example, Loctite 243 is highly oil-resistant. Therefore, while using this adhesive, you get into the gluing process immediately.
However, while using Loctite glue that is less resistant to oil, the process changes. Consider the case of the Loctite 242. As a result of its low resistance to oil, you will first have to wipe the surfaces and ensure that they are dry before going ahead to apply the glue.
3.How Do I Make Loctite Glue Dry Faster?
There are two methods you can consider to help with the faster drying of your Loctite glue. They identify the use of baking powder and the use of a hairdryer. Like most adhesives, the Loctite glue is very sensitive to any form of temperature.
Therefore by turning your hairdryer on and keeping it close to the area where you applied your glue, you reduce the normal drying time of the glue. You should, however, not directly point the hairdryer to the surfaces or have it there for long as it will damage your project.
The second option, which is the use of baking powder, entails sprinkling some amounts of baking powder on the glue. It will act as an accelerator hence reduces the original drying time of your glue.
Besides these two main options, the other alternative is to increase airflow and your room’s circulation. You can easily do this by opening your window, using your breath, or better yet using a fan. While using the fan, however, you have to ensure that the air is not so much as it may destroy the project. This method has actually been précised while continuous handling glue projects are bound to cause headaches and nausea.
Often, buyers have not seen any difference between the Loctite 242 and Loctite 243.
Most of them think that the difference is in their name until they get to experience both of them first hand. Luckily for you, you do not have to buy both of these glues to point out the differences.
You can save your money for something else because this article has already availed you with everything you need to know.
You only have to ensure that whatever you are choosing will serve your specific needs, such as budget, oil tolerance, and even simplicity for desired end results.
