Orthophthalates  

General Purpose Resin
It is a medium viscosity and medium reactive Unsaturated Polyester Resin based on Orthophthalic acid and standard glycols dissolved in Styrene monomer it wets the surface of glass fibers in the form of cloth, roving mat or chopped fibers to produce variety of laminates. It cures rapidly and exhibits smooth and tackfree surface. It is recommended for the manufacture of FRP components by Hand lay up, Spray up, filament winding and Vacuum bag moulding techniques.

General Purpose Gelcoat
This pigmented layer then co-reacts with the moulding resin during the curing cycle to become an integral part of the moulded product. Gelcoat thus provides continuous coloured surfaces without any subsequent finishing operation. Since it reproduces the mould surface exactly, the gelcoating procedure eliminates the fibre pattern which is sometimes objectionable in reinforced polyester parts. The Gelcoat will produce a mirror image of the mould surface and it is possible to produce anything from a porcelain-like finish to a grained textured pattern. The resin vehicles for Gelcoat formulations can be varied over the broad range of properties possible with polyester systems, depending on the type of the service required of the finished moulding. Gelcoat finishes are currently being widely used on boats, bath tubs, automobile and truck parts, furniture, luggage, swimming pools, chemical storage tanks and a variety of similar items.

General Purpose U.V.Stabilised Resin (Ultra Violet Stabiliser)
The properties of this grade is same as that of G.P.Resin with U.V.Stabilised

Rooflight Resin
Its a transperant orthophthalate resin for translucent roofing sheets, domes, structural panels, etc.

Photo Lamination Resin
This resin is same as transparent resin but slightly modified for photo lamination applications.

Rooflight U.V.Stabilized Resin Transparent polyester resin with good optical properties, UV-stabilised, used for making transparent sheets and roofings.

General Purpose Fire Retardant Resin
In common with most carbon compounds, polyester resins are combustible. Completely fire-proof resins do not exist but it is possible to make polyester resins which are flame-retardant or self-extinguishing i.e. the cured resin stops burning once the source of ignition has been withdrawn. The time taken for the resin to extinguish after the withdrawal of the flame can be taken as a measure of the flammability of the cured resin. A polyester laminate has a carbonization temperature of 350oC to 380oC and an auto ignition temperature of 450oC to 470oC.on the basis of tests carried out in the laboratory, it has been demonstrated that a polyester laminate can be subjected to temperatures of up to 200oC for up to 30 minutes without any deterioration in its short term mechanical properties. By visual assessment, one will first register a change in colour of the laminate's surface, which will later become dark and charred. The effective heat of combustion is the amount of energy that is released when a material burns.
