Low Shrink Additive HS-9817 for SMC/BMC
Principal Properties & Application：
HS-9817 is a solution which made by dissolving the saturated polyester in styrene and has a medium viscosity.
Application:
HS-9817 is intended for low shrink SMC and BMC formulations with good surface quality. Depending on the choice and the ratio of UP-resin and high polymer, low shrinkage up to zero shrinkage can be achieved. The formulation can readily thickened with magnesium oxide. Its pigmenting property is limited. Recommended for the productions of electrics applications, automotive parts and etc.
