Renishaw 8045 is a translucent, polypropylene and polyethylene-type polyurethane vacuum casting resin with variable hardness, suited to high-impact and snap-fit parts.
Renishaw 8045 is a translucent, polypropylene and polyethylene-type polyurethane vacuum casting resin with variable hardness, suited to high-impact and snap-fit parts.
Adding a C component in set ratios (8045-1, -2 and -3) softens the cast part, so one resin system covers Shore D 74 down to Shore D 48. It can be pigmented.
