Emulsion polymer isocyanates
Emulsion polymer isocyanate (EPI) adhesives have very good adhesion, gluing difficult wood species very well and gluing metal to wood.
Emulsion Polymer Isocyanate adhesives is a two component adhesive system; a water based polymer cured with an isocyanate. This combination gives glueline performance with the benefits of both thermoplastic and thermosetting adhesive systems such as high flexibility of the glue line, cold setting and excellent cold and boiling water resistance. The systems are fast setting and cold curing and they give light coloured gluelines. The curing process is a combination of a physical process, film formation, and the chemical reactions of isocyanate.
