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
