What Are The Differences Between Loctite 263 and Loctite 270

For further knowledge, here is a detailed explanation of the differences between Loctite 263 and Loctite 270. 

#1. Heat Resistance

Durability greatly depends on the heat-resistant capability of a sealant or adhesive. The heat-resistant level makes a great difference between the Loctite 263 and Loctite 270 thread lockers.

For starters, Loctite 263 is a high heat-resistant adhesive that can resist a maximum of 360°F of heat at once before melting and hampering the bond. It serves incredible durability to your projects.

However, Loctite 270 can withstand even higher heat and serve you extended durability. This sealant can endure temperatures of up to 572°F at once and won’t melt and loosen the bond anytime soon.

#2. Set Time

Even though the set times of Loctite 263 and 270 aren’t too distant in terms of minutes, the difference is significantly considerable in terms of efficiency. 

To start with, Loctite 263 thread locker sets in 10 minutes. However, even though it takes a bit longer to set, this sealant gives you enough time to play with the thread locking.

On the other hand, Loctite 270 sets in just 5 minutes. But as it sets too quickly, you need to work promptly for any customization in your bond.

Last Opinion

After comparing Loctite 263 vs. 270 in great detail, I concluded that Loctite 270 is better than Loctite 263, and I would pick 273 thread locker on any given day.

Also, it creates a durable bond to make sure that the nuts and bolts don’t come off anytime soon.
