Polyamides (Adducts/Ketimines)/Amidoamines

Principal properties
  • Polyamides offer low toxicity, good flexibility and 

toughness, long pot life and good water/corrosion  

resistance

  • Polyamide adducts provide good compatibility (without   induction period) and better cure under adverse conditions than standard polyamides
  • Ketimine polyamides are similar to the performance of standard polyamides, and have better cure under high humid conditions and longer pot life
  • Amidoamines exhibit low viscosity, very good adhesion (particularly to concrete and damp substrates) and

good cure under humid conditions

 

Principal applications
  • Polyamides (adducts) find use in solvent-based, two     component coatings (e.g., primers and finishes),

coal tar epoxy coatings, adhesives, putties, sealants,     cable jointing andelectrical encapsulation

  • Ketimine polyamides mostly are applied to cationic   

electro-deposition coating systems, also used for extending pot-life or curing at damp conditions

  • Amidoamines usually are applied to civil engineering (e.g., concrete bonding, crack injection, flooring
  • tile grouts, etc.), solvent-free/high-solids coatings,  adhesives, electrical encapsulation and wet lay-up laminating
