Hardeners
Introduction of product:
CYDHD-593, a modified fatty amine hardener, is solidified under room temperature. Solidified lacquer film is excellent in anti-chemical erosion. Widely used for pouring, sealing and packing of electronic parts and agglutination of construction materials.
CYDHD-531, a phenolic modified amine hardener, is widely used for various antiseptic engineering, large-scale construction and hydraulic engineering. It is good at acid and alkali resistance.
DMP-30, a promoter of curing, can promote the curing of acid anhydride and amine hardeners. Widely used for casting, laminating of epoxy resin, adhesive, construction and all kinds of coatings.
CYDHD-625, applied with CYD-625, is mainly used for various electrical insulators.
CYDHD-546, 548, an aromatic amine hardener can be cured at room or medium temperature. Widely used for casting and pouring of small appliance, agglutination of civilworks with low viscosity, good mechanical and electrical properties.
