SMC/BMC
MagPro® is a high active magnesium oxide produced in the form of powder by carefully controlled indirect calcination of milled brucite mineral (magnesium hydroxide).
MagPro® is used as a thickening agent in the production of glass-reinforced SMC/BMC composites.
SMC/BMC composition is a mixture of various components: unsaturated polyester or polyacrylic resin, mineral fillers (chalk, flame-retardants), low profile agents, dyes and a thickening agent (chain extender). The thickening agent provides crosslinking and an increase in the viscosity of the composite.
Magnesium oxide for this application should have a high specific surface area and a stable particle size distribution.
The correct selection of thickening agent is extremely important in producing a high-quality composite without moulding flaws, cracks and undulations.
Two grades are available: MagPro®150 and MagPro®170. The right choice of the appropriate grade depends on the formulation and technological parameters.
