AP134-1 PRIMER 500ml 435gm
Techsil AP134-1 is a medium straw-coloured solution of a reactive silicone. When suitable applied as a thin (0.1mm) film to glass, metal, or masonry substrates, it will function as an adhesion promoter for polyurethane sealants. In this application, AP134-1 is particularly useful in promoting adhesion under conditions of high humidity or in the presence of water. Techsil AP134-1 can be applied by either brushing, flooding or wiping and a cure time of 15 minutes at room temperature is recommended.
