KEMAPRIME SC has been designed to function as a high-performance, single-component, moisture-cure, urethane primer system for use on concrete. Its low viscosity allows it to penetrate porous surfaces, leaving a bubble-free coating. Working time is adjustable by selective addition to catalyst. It also exhibits a low sensitivity to substrate moisture, leaving only minimal bubbling when applied to damp surfaces.


  • VOC Exempt (less than 1% VOCs)
  • Penetrates and seals the surface, leaving a smooth, pinhole, and bubble-free coating
  • Excellent adhesion to a variety of substrates
  • Good physical properties
  • Outstanding stability at low temperatures
  • Defoamers or de-aerators can be used to further minimize pinholes.

Recommended Uses:

  • Concrete and wood primer for polyurethane and polyurea spray coatings
  • Industrial flooring, roofing, decking, truck bed liners, pipeline, and tank coatings


  • Cured material is amber and translucent, with a slightly musty odour
