KH‐560 is an 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.
