Product Description

 

Product Description

Discription:
Epoxy hardener HW-558 is phenalkamine modified epoxy resin curing agent with unique performance, suitable for solvent-free or high solid epoxy primer systems. The unique structure of cardanol modified phenalkamine gives the curing agent and its derived coatings unique properties. The curing agent has the advantages of fast curing, especially suitable for use under low temperature conditions, suitable for use all year round.

Performance: 
1. Under normal temperature and low temperature conditions, it has fast curing and long operation period; the lowest curing temperature can reach 0°C;
2. Wider construction mixing ratio;
3. Good chemical resistance;
4. Good compatibility with a variety of solvents and resins;
5. Outstanding anti-corrosion performance;
6. It still has excellent adhesion on wet surfaces;
7. Good moisture resistance during curing;
8. Solvent free;
9. Its raw materials are natural and renewable.

Application:
Marine coating, anti-corrosion medium, primer coating, adhesive, sealant, and composites, etc.
