Description
PROXAN®- KV 2 R is a two-component joint sealant for joints whose practical widths have the potential to expand by up to 25%. The product is pourable, has a medium viscosity and is suitable for horizontal floor joints with a maximum gradient of 10%. PROXAN®- KV 2 R is primarily intended for railway construction, as its elastic properties offer optimum absorption of the various movements between the rail and adjoining flooring. When used properly, PROXAN®- KV 2 R seals the rail joint and prevents the ingress of moisture.
