The Loctite 431 super glue is a 20g, low viscosity for use with cyanoacrylate adhesive. It is designed for the assembly of difficult to bond materials which require uniform stress distribution and strong tension and/or shear strength. The product provides rapid bonding of a wide range of materials, including metals, plastics and elastomers. The LOCTITE® 431™ is also suited for bonding porous materials such as wood, paper, leather and fabric.
New health and safety improved formulation without adding Hydroquinone (HQ) and/or 2,2'-Methylenebis(4-methyl-6-tert-butylphenol) (MMBP). These raw materials function as shelf-life stabilizer and represent a small percentage.

Better resistance to heat and moisture
Non-efflorescent fixtures
Better solvent resistance
Greater filling capacity
Does not emit odour during use
General-purpose instant adhesive
Ideal for porous substrates, where lower viscosities may be required to be absorbed
Use when the bond line is not horizontal or unequal
Drying slower than Loctite 401- Makes product alignment easy
Excellent adhesion to most substrates
Fixture time is 5 to 10 seconds
New and improved health and safety formulation
