Best Practices for Elantas (Altana) K-20

*See Terms of Use Below
1. Surface Preparation
  
  Apply to dry oil-free surfaces. Remove mold release from plastic surface. When bonding to metals, degrease and dry. Chemical etching of the metal surface gives optimum results.
2. Application
  
  Apply adhesive with spatula or stiff brush to each surface. Apply light pressure to ensure good wetting and contact of the bonded surfaces.
3. Curing
  
  Pot life of mixture is 20 minutes at 25°C (77°F). Cure is achieved in 24 hours at 25°C (77°F). Cure can be accelerated by heating at 65°C (149°F) for 2 hours
4. Clean-Up
  
  Clean equipment before the adhesive hardens, a good hydrocarbon solvent is recommended.
