| Menzolit® SMC 0400 is a sheet moulding compound based on unsaturated polyester resin. The product is glass fibre reinforced and contains mineral fillers. In case of fire the product doesn’t melt, neither does it form droplets nor is smoke generation excessive. The material is compression moulded in heated steel moulds. It is a must to work with chrome plated tools. The product contains no halogens or heavy metals. Menzolit® SMC 0400 is a Class-A SMC for exterior body applications on cars, LCV´s and trucks. These compounds mould to parts with good up to excellent surface quality for medium bake in-line and off-line painted (100 – 140°C) body panels. Surface defects like waviness, fibre patterns and orange peel do not occur with this products. To achieve the highest surface quality, we recommend that tool surfaces are mirror polished. To ease demoulding we highly recommend chrome-plating of tool surfaces. Menzolit® SMC 0400 allows. The product shows very good adhesion to paint or In Mould Coating (IMC). Because of its zero shrink properties warpage is eliminated and parts reproducing the dimensions of the cold mould can be produced.&& |
