GUP® – based additive masterbatch for epoxy resin

Product Description

ADEPOXYGUP® is an additive masterbatch based on GUP® few layer graphene, specifically designed to provide superior mechanical properties to epoxy resin for the use in very demanding reinforced composites. It is suitable for all processes, prepregs, filament winding, pultrusion, infusion or 3D printing with easy integration and flexibility in design of multifunctional materials.

Product Data

The values shown above are from a typical sample of ADEPOXIGUP®. They should be used as a basis and not as an absolute value. There may be slight deviations from batch to batch, but all parameters will fall within the specifications listed above.

PROCESSING GUIDELINES & ADDITION RATE

ADEPOXYGUP® is added to the neat resin to be processed. The product should be stirred well before start introducing it into any formulation, eventually increasing the temperature between 50 and 55 °C to reduce its viscosity. First add the required amount of ADEPOXYGUP® to the neat resin with a continuous and vigorous mixing till to obtain a final homogeneous mixture. The hardener is added according the conventional processing conditions in a proportion depending on the final epoxy equivalent weight (EEW) of the formulation. The amount of hardener is reduced in proportion to the new epoxy equivalent of the resin blend.

We suggest to use at least 15-20 wt% of ADEPOXYGUP® in the neat epoxy resin to achieve significant improvements in the final formulation. The compatibility between ADEPOXYGUP® and all other formulation components should be tested separately before starting formulation development.
