MCP Resins Solve Thickness Casting Problems

MCP has introduced two polyurethane resins formulated to enable thin and thick-wall components to be cast by hand quickly and precisely.

Curing in only three to ten minutes depending on thickness, MCP resins 410 and 420 are said to be ideal for hand-casting prototype models, foundry patterns and models, and jigs and fixtures. Also suitable for short production runs, both materials can be filled for the mass casting of exceptionally thick sections.

With a very low viscosity and cured shrinkage of just 1 per cent, the two-part resins achieve close dimensional and geometric replication of the mould shape, no matter how intricate it may be.

In the cured state, castings have a tensile strength of 30N/mm2, flexural strength of 40N/rnm2, hardness of 75 Shore D, and temperature resistance of 80C.

Both resins are light amber as standard but can be coloured to suit the application.
