Products Description
Trixene BI 7774 is a highly flexible polyurethane resin used to enhance epoxy The flexibility of the resin. Epoxy resins toughened with Trixene BI 7774 retain many of the properties of epoxy systems, however, the inherent brittleness of epoxy resins will be improved by reacting with polyurethane and amine curing agents at room temperature.
Trixene BI 7774 is a solvent-free aromatic curing agent with blocked The isocyanate component, thus eliminating the sensitivity to humidity and improving storage stability at room temperature.

However, it is still recommended to keep the product in a closed container at 10-30°C to ensure the performance of the product. In such an environment, the sample can be stored for 6 months. Avoid contact with eyes and skin, detailed handling methods can be based on MSDS. During storage, samples should not be exposed to temperatures exceeding 40°C, as this would cause pressure to build up in the container. At extreme temperatures, toxic gases are released that pose a health hazard. Security When necessary, LANXESS has the right to modify and select product specifications.
