Silane coupling agent KH-792

Feature

Improve the strength and toughness

Improve the adhesion of a variety of substrates

Available cohesive interface rather than split off split off

It can reduce the resin at a high temperature gas evolution

Can reduce the amount of resin in the sand,good dispersion

Improve the compatibility with the resin properties of diamond

Free use promote coating with the surface of the coating adhesion primer

Can improve the moisture resistance and increased compression resilience

Greatly improves the strength of the sand core, so that the surface is flat and casting products more smooth, and reduce the cost of casting
