Product family
Samrat Poly Resins manufactures these 10 grades for the jobs a general-purpose polyester resin is not the right answer to — a stated chemical- or corrosion-service requirement, a closed-mould compound, a cultured-marble or engineered-stone line, pultrusion, mould tooling, or a putty base resin. Each is a distinct published product, and its page shows the technical documents issued for it.
None of these is published as "better" than a GP grade — they are formulated for different requirements. Choose from the requirement your drawing or customer specification actually states, and confirm suitability against the grade's own data rather than the family name.
