Product Description

ADESTERGUP® GF is an additive based on few-layers graphene GUP® specifically designed to provide superior mechanical properties to unsaturated vinyl ester and polyester resins for the use in very demanding glass fiber reinforced composites.

Key Features and Benefits 

increases modulus, flexural and tensile strength, toughness
contain verified few-layer graphene GUP®

improves stiffness

thermal dissipation – avoid hot-spots during curing process, better thermal cycle resistance
reduces shrinkage

ease of formulation without a significant increase in viscosity of the host material

improves wear resistance

Main Applications

Boat & Marine structure


Wind Turbines

Piping & Tanks

Sport Equipment

Building & Construction


ADESTERGUP® GF is added to the neat resin to be processed, shortly before the curing process. The product should be stirred well before start introducing it into any formulation. First add the required amount of ADESTERGUP® GF to the neat resin with a continuous and vigorous mixing till to obtain a final homogeneous mixture. After being added, the resin system must be processed within a maximum of 24 hours. The length of time varies depending on the type of resin and quantity of additive.

We suggest to add 1.5 – 3 wt% of ADESTERGUP® GF based on the total formulation to achieve significant mechanical improvements. The compatibility between ADESTERGUP® GF and all other formulation components should be tested separately before starting formulation development.

GUP® – based additive masterbatch for glass fiber reinforced, radical curing systems based on unsaturated vinyl ester and polyester resins.
