Dertophene T Terpene phenolic resin DRT Tackifier >> Terpene >> Terpene phenol ADHESIVE >> Hot-melt ADHESIVE >> Solvent based ADHESIVE >> Water-based Our terpene phenolic resins are based on an original DRT process specifically designed to improve the adhesion on various substrates when included in an adhesive formulation. Our first production grade, DERTOPHENE T, has now been successfully used for more than 25 years in hot melt adhesives for packaging and bookbinding applications, giving the hot melt bond a high degree of flexibility even at low temperature. As a result of its exceptional compatibility with most elastomers, DERTOPHENE T is also recommended for solvent and water based adhesive formulations. Terpene phenolic resin. Used as a tackifier in adhesives. Provides improved adhesion on various substrates. Gives the hot melt bond a high degree of flexibility even at low temperature and very good compatibility with most elastomers.
