Loctite 401 General Purpose Instant Adhesive 20g

LOCTITE 401 is a fast-curing, general-purpose instant adhesive designed for high-strength bonding on close-fitting parts and difficult-to-bond materials. 

Key Features

• Fast Curing: Fixes and bonds within 3 to 10 seconds.

• Versatile Substrates: Works exceptionally well on metals, plastics, elastomers, and rubber. 

• Porous Materials: Uniquely suited for absorbent or porous surfaces like wood, paper, leather, and fabric. 

• Temperature Range: Withstands temperatures from -40°C to +120°C. 

• Low Viscosity: Clear liquid formulation spreads easily for uniform stress distribution. 

Best Practices for Application

• Surface Preparation: Surfaces must be clean, dry, and mating tightly. It is not gap-filling. 

• Amount: Use a minimal amount (just one to three small drops). Excess glue slows down the curing process. 

• Special Primers: For polyolefins or tricky plastics like PE, PP, or PTFE, pair it with a specialized primer like Loctite 770
