Product characteristics and uses:
1. The high-quality secondary amine structure of KH-170/KH-270 makes the reaction more gentle and delayed, and the stability is better; at the same time, there are more hydroxyl groups after hydrolysis, this product can be used as epoxy resin, polyurethane resin With other amine-terminated or modified resin cross-linking agents, this modification gives these polymers moisture-curable properties.
2. This product is very suitable for polyurethane, RTV, epoxy, phenolic adhesives and sealants, to improve the dispersion of pigments and fillers and to improve the adhesion and water resistance of adhesives to inorganic materials such as glass and metals.
3. KH-170/KH-270 has higher cross-link density after hydrolysis, so it is also suitable as filler surface treatment and metal anti-corrosion pretreatment agent.
