BEPU 6030 is 1000g 500g Twin-Pack two-component polyurethane potting compound. After curing, it will be light yellow and transparent.
It is used in two-component sealing, filling, flame retardant and other fields. The raw material does not contain heavy metals, is green and environmentally friendly, has wide process operability, high physical properties of the finished product, and good adhesion to the substrate. It can be cured at room temperature and under heating, and can be cured in depth, with less heat release and low shrinkage during curing; excellent flexibility after curing, and good flame retardant effect.
