1. Loctite 277 is a one-component, high-viscosity, high-strength red threadlocker (anaerobic adhesive), which is suitable for permanent ridge locking and sealing threaded fasteners. 2. Large-size bolts, nuts and studs can be fixed and sealed, so as to resist disturbance and prevent loosening caused by vibration of components such as pumps, motor assembly bolts, gearboxes or presses.

Summary. Loctite 243 Adhesive Solid Adhesive is oil resistant, medium strength, heat aging resistant, and fast curing for locking and sealing threads below M20. Loctite 242 threadlocker medium strength, general purpose, thixotropic viscosity.

For locking and sealing of M6-M20 threads.

Loctite 243 Adhesive is oil resistant, medium strength, heat aging resistant, and fast curing for locking and sealing threads up to M20. Loctite 242 threadlocker is a medium-sized wreath for shed strength, general purpose, thixotropic viscosity. It is used for locking and sealing of M6-M20 threads.

Loctite 277 adhesive is suitable for long-lasting locking and sealing of threaded fasteners, which cures between metal seal surfaces that lack oxygen to prevent loosening or leakage of threaded fasteners caused by vibration or shock, mainly in large bolts (M25 and larger).

So here, let's say that the difference between Loctite 277 and 243 glue is mainly for the above use, and the size of the 277 can be used is larger.

Compared with the Lerang Dongtai 290 and 243 models, in terms of performance, quality, and function, the Loctite 290 model is better.

In terms of performance, the overall performance of the Loctite 290 model is better than that of the Loctite 243 model. The 290 models of Caitan Annihilation use newer processors, which have more powerful processing power, run faster, and can complete tasks faster; The 243 model has weaker processing power, runs slower, and is more prone to stuttering.

In terms of quality, the shell of the Loctite 290 is made of high-quality metal, which is easy to maintain even after long-term use. The Loctite 243 is made of polycarbonate, which is prone to deformation and damage if used regularly.

In terms of functions, the Loctite 290 has more functions, such as fingerprint recognition, fingerprint payment, etc., which can complete tasks more conveniently and quickly; The Loctite 243 lacks these features, so it is not as functional as the 290.

In short, in terms of performance, quality, and functionality, the Loctite 290 is better than the Loctite 243.

Loctite 290 is better, Loctite 290 is a positive mold excited by anaerobic glue, can also be called thread glue, that is, the glue on the screw, and then tighten it is not easy to loosen, this anaerobic glue is very easy to solidify in the absence of oxygen, but he does not solidify after encountering oxygen, because of his characteristics, so he is generally used for screws, the socks are fixed, Loctite 243 effect is not so good, I hope my can help you, can code the town to help a like?

1.Loctite glue has low shrinkage.

Loctite epoxy resins are tightly aligned to allow no low molecular weight separation during curing, and they are able to be formulated into solvent-free adhesives, so they typically have low shrinkage. If the right filler is used, the shrinkage can be reduced.

2.Strong corrosion resistance.

Loctite epoxy resin has stable benzene rings, ether bonds, and a dense structure after curing, and epoxy adhesives are highly resistant to atmosphere, moisture, chemical media, bacteria, etc., so they can be used in many harsh environments.

3.Good technical performance.

Depending on the type of hardener used, epoxy adhesives can be cured at normal, medium or high temperatures. Typically curing requires only contact pressure, and most epoxy adhesives are solvent-free and easy to handle. Generally, the construction viscosity and curing speed of epoxy adhesive can be adjusted by formula to meet various bonding requirements.

This not only ensures the quality of the bond, but also simplifies the curing technology and equipment.

4.Excellent electrical insulating properties.

After the epoxy resin is cured, it can obtain outstanding electrical insulation functions:1Breakdown voltage 35kV mm; 2.Volume resistance 1015 ·cm; 3.Dielectric constant 3 4 (50Hz); 4.Arc resistance 100 140s;

5.Adaptable performance.

Epoxy resin adhesive can change its components (hardener, toughening agent, filler, etc.) to obtain a series of adhesive formulations with different functions to get used to various different needs, and mixed with many modifiers (such as phenolic resin, nitrile rubber, etc.) to produce various types with different functions.

6.High heat resistance and low water absorption.

Generally, the application temperature of bisphenol A epoxy resin is from -60 +175, sometimes up to 200 for a short time, and the water absorption of epoxy resin is small.

What is the way to cure Loctite 503 glue? Hello, glad to answer for you. The main component of 503 glue is a common name for a large class of fast adhesives of ethyl cyanoacrylate with a side chain, and ethyl acrylate is an important chemical adhesive with a wide range of applications, ethyl cyanoacrylate is generally liquid at room temperature, and the main difference between the 503 glue of the same variety is in the size of the side chain, and different additives will also bring certain differences in the properties of the glue itself.

It is different from the solvent glue we usually use when making models. 503 glue is a kind of resin glue, which does not have a dissolution effect with the host, but relies on the force between the ethyl acrylate formed during the curing process and the host to form a firm adhesion effect. The curing process of 503 glue requires heat exchange, and the better the heat exchange conditions, the faster the curing, which is why bonding metals with good thermal conductivity is faster than bonding plastics, and a thin layer of glue also dries much faster than a large drop of glue.

503 glue is composed of (A) butyrine butyrine compound glue butyl acetate solution and (B) F01-6 varnish butyl acetate solution. It is mainly used for the bonding of oil-resistant and heat-resistant rubber based on nitrile rubber and the adhesive tape bonding based on butadiene rubber. The storage period of 503 glue is half a year.

Hope mine can help you! Do you have any other questions?
