Description

gamma-methacryloxypropyltrimethoxysilane KH***0Introduction Chemical Name : gamma-methacryloxypropyltrimethoxysilane CAS NO. : ********0 Molecular Formula:CH2=C(CH3)COO(CH2)3Si(OCH3)3 Foreign Company&#**9;s Trademark: A***4(America Union Carbon) Z****0(Dowcorning) KBM***3(ShinEtsu) GF*1(Wacker) Features and Benefits The methacryloxylsilane produced by silane KH***0. • Significantly improves composite strengths when the composite is reinforced with fibreglass roving sized with a typical polyester-compatible formulation. These formulations normally incorporate silane coupling agents, film-forming resins, lubricants and antistatic agents. • Enhances the strength performance, both initially and after wet-conditioning, of cured polyester resin composites filled with silica, glass, silicates and many metal oxides. • Enhances the wet electrical properties of many mineral-filled composites, such as crosslinked polyethylene and polyvinyl chloride. • May be copolymerized with vinyl acetate and acrylate or methacrylate monomers to prepare silylated polymers that are moisture-curable. These silylated polymer may be used in coatings, adhesives and sealants to provide superior adhesion and durability. Typical Physical Properties Determined on commercial material whose properties may vary within the specification limits. _____________________________________________________ Physical Form Clear liquid Colour, Pt-Co Max *0 Specific Gravity at *0°C, g/cm3 1.**3 – 1.**3 Refractive Index, nD *5°C 1.***5 –1.***0 Purity, % Min *7.0 Solubility silane KH***0 is soluble in ethanol, methanol, isopropanol, acetone, benzene, toluene, and xylene. After hydrolysis it is soluble in water with adequate stirring if the pH is adjusted to 4.0. Hydrolysis releases methanol.
