PU 2KR 31

PU 2KR 31 is a two-component polyurethane adhesive characterized by a low viscosity, rigid and transparent highly resistant to impacts, impacts and UV rays.

PU 2KR 31 was developed for casting in sections from 1 to 5 mm when a high degree of transparency is required. Make sure that the mold is made of a material that can withstand the reaction temperature of the mixture.
