Application

XD-5503-Aminopropyl triethoxysilane (APS) (CAS No. 919-30-2), is a universal amino silane used as versatile amino functional coupling agent in a broad range of applications to provide superior bonds between inorganic substrates and organic resins and polymers.

Coatings, Adhesives and Sealants
XD-550, 3-Aminopropyl triethoxysilane, is an excellent adhesion promoter in acrylic coatings, adhesives and sealants. With polysulfide, urethane, RTV silicones, epoxy, nitrile, and phenolic adhesives and sealants, XD-550 silane improves pigment dispersion and maximizes adhesion to glass, aluminum, steel and various other substrates.
Glass-Reinforced Resin Systems
In glass-reinforced thermosetsXD-550 silane enhances the flexural, compressive and inter-laminar shear strengths before and after exposure to humidity. XD-550 silane greatly improves wet electrical properties.
Glass-reinforced thermoplastics, polyamides, polyesters and polycarbonates exhibit increased flexural and tensile strengths before and after wet exposure when XD-550silane is used.
Glass Fiber and Mineral Wool Insulation
As a phenolic resin binder additive, XD-550 silane imparts moisture resistance and allows recovery after compression.
Mineral-Filled Resin Systems
XD-550 silane maximizes the physical and electrical properties of mineral-filled phenolics, epoxies, polyamides, polybutylene terephthalate and a host of other thermoset and thermoplastic composites. Filler wetting and dispersibility in the polymer matrix are also improved.
Foundry Applications
In shell molding, XD-550 silane strengthens the bond between the phenolic binder and foundry sand.
Grinding Wheels
XD-550 silane promotes an improved, water-resistant bond between the abrasive grit and phenolic resin binder.
 

Packing and Storage

200L steel or plastic drums, or 1000L IBC, other packing is available upon reques.

Stored in sealed, cool and ventilated conditions with a 12-month shelf life
