Application
1. Coatings, Adhesives and Sealants
The aminosilane is an excellent adhesion promoter in acrylic
coatings, adhesives and sealants. With polysulfide,urethane, RTV
silicones, epoxy, nitrile, phenol formaldehyde resin, adhesives and
sealants, the product improves pigment dispersion and maximizes
adhesion to glass, aluminum and steel.
2. Fiber glass Reinforcement
In fiberglass reinforced thermosetting plastics and thermoplastics,
the aminosilane enhances the flexural, tensile and interlaminar
shearing strengths before and after exposure to humidity. This
product greatly improves wet electrical properties. Fiberglass
reinforced thermoplastics, polyamides, polyesters and
polycarbonates exhibit increased flexural and tensile strengths
before and after wet exposure when this silane is used.
3. Glass Fiber and Mineral Wool Insulation
As a phenolic resin binder additive, the aminosilane imparts
moisture resistance and allows recovery after compression.
4. Mineral Filler and Resin Systems
The aminosilane maximizes the physical and electrical properties of
mineral-filled phenolics, polyester resin, epoxies, polyamides,
polycarbonate and a host of other thermoset and thermoplastic
composites. Wettability and dispensability of filler in the polymer
matrix are also improved.
5. Foundry Application
In shell molding, the aminosilane strengthens the bond between the
phenolic binder and foundry sand.
6. Grinding Wheel Manufacture
The amino silane promotes an improved, water resistant bond between
the abrasive grit and phenolic resin binder.
7. Wood plastic composite production
The mechanical properties of composites made of wood meal, such as
impact strength, bending strength and bending modulus, will be
improved after these composites are processed with this product.
