Mould Resin HS-4401W/M/S
n Characteristics and main uses:
HS-4401W/M/S is vinyl type unsaturated polyester resin, thixotropic agent and accelerator have been added, low shrinkage, good dimensional stability of products, smooth surface. It has good infiltration of glass fibre, convenient construction, high toughness, high resistance to cracking, high heat distortion temperature, excellent heat degradation resistance and superior strength retention under high temperature. It is suitable for making common FRP moulds.
HS-4401W is winter type, suitable for November-March (below 15ºC);
HS-4401M is a spring/autumn type suitable for April-May, September-October (15-25ºC);
HS-4401S is a summer type suitable for June-August (above 25ºC).
