REVERSOL P-9941

Reversol P-9941 is a non-promoted clear orthophthalic unsaturated polyester resin of high unsaturation which has good heat and chemical resistance. Reversol P-9941 is ideal for pultrusion of profiles. This resin can be used to back up other specialty resins, either to produce a combination of properties or for economy. Reversol P-9941 can be used to laminate Celmar (glassfibre backed polypropylene) and to reinforced suitably treated µPVC to upgrade the operation conditions of the material. This resin is also suitable for the fabrication of moulds for heat-assisted contact moulding and hot-press moulding processes.
