Lavatex SM (Surfacing mat) is mainly used in the surface layers of FRP products. It is divided into winding S-SM series and hand lay-up S-HM series. S-SM are mainly used on pipe and tank winding process. It can improve the product surface property on corrosion resistance,compressive strength,seepage resistance,and longer service
life. S-HM is chiefly used in the product with complicated geometric curve. It has the advantages of good pattern fitness, quick resin permeation. It can raise the intensity and corrosion resistance of products
