Detailed Description

Typical Technical Data The below values are not intended for use in preparing specifications. Please confirm with us prior to writing specifications on this product. CAS NO.: 919-30-2 EINECS NO.: 213-048-4 Appearance: Colorless transparent liquid Colour (Pt-Co): 25 max Specific Gravity (ρ20°C,g/cm3): 0.940~0.950 Refractive Index ( ): 1.4180~1.4220 Purity (by GC, %): 98.0 min Properties In addition to its application as an adhesion promoter in formulations and primers, silane AC-220 functions as a surface modifier in fillers and pigments, where it improves the dispersibility of the filler and the mechanical properties – such as flexural strength, tensile strength and modulus - of the composites. The silane also reduces the filler's sedimentation tendency in the uncured polymer. Silane AC-220 also greatly increases water (vapor) and corrosion resistance. Applications Silane AC-220 is an vital additive for many applications, such as follows: Glass fiber or glass fabric composites：As a finish or size constituent Mineral fiber insulating materials and abrasives: As an additive to phenolic resin binders Foundry resins: As an additive to phenolic, furan and melamine resins Sealants and adhesives: As a primer or additive and for chemical modification Mineral-filled polymers or HFFR cables: For pretreatment of fillers and pigments Paints and coatings: As an additive and primer for improving adhesion to the substrate As a primer for glass and metal
