T26 is a one-part structural resin for producing composites with low porosity and increased operating temperature.
—Read allT26 is a one-part structural resin for producing polymer composites with low porosity and increased operating temperature. This resin has a low viscosity at temperatures above 60°C, which provides its high processability and the possibility to manufacture composites with vacuum infusion and RTM.
It is our best-seller for applications that requires high-grade epoxy resin.
