A versatile crosslinker connecting organic and inorganic worlds:

• Superior Adhesion: Reacts with active hydrogen atoms (in hydroxyl, amine, thiol groups) to covalently bond resins to glass, metal, and inorganic fillers.

• Polyurethane Modifier: Essential for end-capping polyurethane prepolymers to create moisture-curing PU sealants with excellent weather resistance.

• Coating Additive: Improves corrosion resistance and durability in primers and metal coatings.

• Resin Synthesis: Used to synthesize silylated polymers (MS Polymers) for next-generation solvent-free adhesives.

Packaging: 200kg Iron Drum / 1000kg IBC Tank.

Storage: Highly moisture-sensitive. Store in tightly sealed containers under dry nitrogen atmosphere. Shelf life: 9-12 months.
