introduction:
product: silane couping agent kh-560
chemical name: 3-glycidoxypropyltrimethoxysilane
cas no.: 2530-83-8
einecs: 219-784-2
molecular formula: c9h20o5si
kh-560 is a epoxy-functional silane, it is a clear, light straw liquid. kh-560 may be used as a coupling agent in polysulfide and polyurethane caulks and sealants, in mineral-filled or glass-reinforced thermosets and thermoplastics, and in glass roving size-binders. it is particularly employed as an adhesion-promoting additive in waterborne systems, e.g. improving the adhesion of acrylic latex sealants.
note: kh-560 reacts with water.

applications:
improves dry and wet strength in cured composites reinforced with glass fiber rovings.
enhances wet electrical properties of epoxy-based encapsulate and packaging materials.
eliminates the need for a separate primer in polysulfide and urethane sealants.
improves adhesion in waterborne acrylic sealants and in urethane and epoxy coatings.
