As the earliest tackifying products, natural sourced terpenic resins have become essential in many formulations. Their compatibility with a wide range of polymers combined to their high tack lead to systems with high adhesion and cohesion.

Benefiting from its 30-year leading position in the pine tree chemistry and expertise in tackifiers, DRT is proposing a brand new generation of terpenic resins with enhanced performance to help you meet most of your day-to-day challenges.

DERCOLYTE® and DERTOPHENE® terpenic resins are water-white tackifying resins with improved durability of adhesion. Their large and consistant range make them highly versatile to suit most of formulation kinds, from Hotmelt, water-borne, to solvent-borne adhesives.

Today, in a highly fluctuant economy environment, their performances, equal to most petrochemical based tackifiers, and sustainable availability ensure a successful business development
