Polyurethane Concrete Stamp
POLYCPU Polyurethane material supplier has been providing perfect liquid polyurethane for making concrete molds, stone molds, concrete stamps.
Polyurethane Concrete Stamp
MDI polyurethane also called PU mold rubber, it is two component room temperature curing PU system. Because PU mold rubber series is specially designed for mold making, it has soft hardness, good flexibility, good toughness and high physical properties.
Polyurethane Concrete Stamp Description
MDI polyurethane is two components with high strength and high physical properties, mostly suitable for concrete stamps casting. Use this MDI Polyurethane to make the rubber mold for a medium and large scale, concrete casting project, formliners, veneer stone manufacturing, artificial stone, sculptures, plaster decorative surfaces and decor. Liquid polyurethane mold rubber have Various hardness for choose, convenient one to one mix raio.
