Unsaturated polyester resin series
Unsaturated polyester resin is one kind of thermosetting resin. As one kind of low molecular polymer, it is flow thick liquid,It can happen copolymerization in the existing of initiator and becomes solid. Unsaturated polyester resin has excellent properties of process, It has good Viscosity in room temperature, thus it can be reformed in normal temp. It can be used in large GRP products, with good Properties, mechanical properties and anticorrosive properties.

Uses
Epoxy resin has good adhesion and resistance to chemicals and insulation. It cab be used in industrial anticorrosion to produce clay and mortar, anticorrosive floor,epoxy anticorrosive coating, GRP vessel, pipe, trough, lining of GRP; or used as adhesive. It also can be used in the insulation of electrical products. |
