Application:

1. coatings, adhesives and sealants: an excellent adhesion promoter to glass, aluminum, steel and other inorganic surface in acrylic, polysulfide, urethane, rtv, epoxy, nitrile and phenolic adhesive, sealants and coatings.

2. glass fiber and mineral batt: improve the moisture resistance and mechanic strength.

3. resin-base composites: greatly enhance the flexural, compressive and interlaminar shear strengths before and after exposure to humidity. improve wet electrical properties.

4. resin-sand foundry: strengthens the bond between phenolic or furan binders and silicon sand.

5. grinding wheels: promotes an improved, water resistant bond between the abrasive grit and phenolic resin binders.
