Thermosetting

These resins are mixed with low alkali borosilicate E type glass when begin polymerized to form a matrix structure called as Fiber Glass Reinforced Plastic (FRP/GRP). All resin systems are also available in fire retardant grade.

Isopthalic:

This is an unsaturated polyester resin based on isopthalic acid. Resistant to weak organic/inorganic acids, minerals, alkalies, salts but sensitive to oxidizing acides, strong alkalies, halogens. Heat resistance upto 60°C.

Bisphenol:

This is modified bisphenol fumarate polyester resin having minimum ester linkages. Resistant to organic/inorganic acids, alkalies, salts & sensitive to solvent. Heat resistance upto 95°C.

Vinylester (GP & Superior):

This is unsaturated polyester resin based on polymer having epoxy backbone for GP grade & epoxy phenolic backbone to superior grade. Resistant to oxidizing & other acids, alkalies, salts & solvents. Sensitive to aromatic hydrocarbons of alcohols. Heat resistance upto 110°C.

HET Acid or Chlorandic:

This is HET acid based unsaturated polyester resin. Resistant to oxidizing acids, chlorine, salt but sensitive to solvents & strong alkalies. Heat resistance upto 120°C with excellent fire retardant properties.

NPG Isopthalic:

These are neopentyl glycol isopthalic acid based unsaturated polyester resin. Chemical resistance same as isopthalic but heat resistance upto 100°C.

Epoxy:

Resistant to weak acids, solvents, salts, bases but sensitive to alkalies, chlorine, strong acids. Heat resistance upto 100°C. This is hot cured process of lamination.
