3205 Epoxy Curing Agent
3205 is a curing agent for epoxy systems, based on a modified low viscosity amine. 3205 is an ideal curing agent for civil engineering, industrial maintenance, industrial floorings, tank linings, concrete adhesives; it is suitable for use with liquid and solid epoxy resins for the formulation of primers, adhesion promoters for concrete (bond coats new to old concrete), solvent-free or low solvent systems. Main characteristics of epoxy system based on 3205 are:
- Water and corrosion resistance
- Excellent adhesion
- Impact strength
- Low viscosity
