Product Application Of
1.Inorganic filler surface modification
Suitable for surface treatment of calcium carbonate, talc powder, kaolin, wollastonite, mica powder, glass fiber and other inorganic fillers. It improves the dispersion and compatibility between filler and plastic, rubber and resin matrix, effectively reduces formula viscosity, enhances product tensile strength, impact resistance and heat resistance, and is widely used in modified plastics, rubber compounds and composite materials.
2.Building materials waterproof and anti-corrosion
Used for permeability waterproof and anti-corrosion protection of concrete, natural stone, ceramic tile, gypsum and cement-based materials. It can penetrate into capillary pores of base materials, form permanent hydrophobic protection inside and on the surface, prevent rainwater, moisture and chloride ions from invading, inhibit steel bar corrosion and concrete carbonization, and is suitable for bridges, highways, municipal projects and exterior wall waterproofing.
3.Coatings, adhesives and sealants
Used as adhesion promoter, hydrophobic additive and crosslinking auxiliary agent for solvent-based and water-based coatings, architectural adhesives and silicone sealants. It improves the bonding performance of coatings and adhesives on glass, metal, aluminum alloy and concrete substrates, and upgrades the film’s water resistance, weather resistance, stain resistance and scratch resistance.
4.Metal surface anti-rust treatment
Applied to surface passivation and anti-corrosion treatment of carbon steel, aluminum, copper and other metals. It forms a compact hydrophobic protective film on the metal surface, isolating air and moisture, slowing down oxidation and electrochemical corrosion, and suitable for daily anti-rust protection of metal parts and hardware products.
5.Other industrial fields
It can be used for textile water-repellent finishing, mold release agent for plastic and rubber molds, surface anti-fouling modification of ceramics, as well as auxiliary agent for industrial drying, isolation and anti-caking in chemical industry
