Sika® Activator-309P - 100ml

Sika® Activator-309 P is a solvent-based, colourless adhesion promoter that reacts with moisture and deposits active groups on the substrate. These groups act as a link between substrates and primers or sealants/adhesives. Sika® Activator-309 P has been specially developed for the treatment of pinchweld substrates such as paint, cut polyurethane, etc. prior to the application of Sika's polyurethane adhesives.
