Unsaturated polyester resin; supplier-listed for button and small casting work.
About this product
Samrat FRP Traders supplies and imports Button Grade Resin for the Nepal market. Current Samrat Poly Resins, India documentation identifies Button Grade Resin as an unsaturated polyester casting resin formulated for buttons and other small decorative mouldings.
The important distinction for buyers is that this is a casting grade, not a laminating resin. Where a general-purpose resin is optimised to wet out and bind glass fibre reinforcement for structural strength, Button Grade Resin is a semi-liquid, transparent grade designed for clarity, hardness and a fine, polishable surface — properties that matter when the cast part itself is the visible, finished product.
Supplier documentation lists a viscosity of 1,100 cPs, a 9.5-minute gel time, 33% styrene content and a cure time of around two hours, using an MEKP catalyst and a cobalt octoate accelerator. The relatively high viscosity suits controlled casting into button and small-part moulds rather than fast reinforcement wet-out.
Samrat FRP Traders can help Nepal buyers confirm whether Button Grade Resin fits their button, fashion-accessory or small-casting work. For current pricing, availability and packaging options in Nepal, contact Samrat FRP Traders through the enquiry page.
What this means for buyers
Casting vs laminating
Button Grade Resin is a casting grade used on its own without fibreglass reinforcement, not a laminating resin. If you need structural FRP lay-up, review GP Clear Resin instead.
Finish and hardness
The grade is supplier-listed for clarity, hardness and a fine, polishable surface, which is what button and decorative casting work depends on. Pigmented work is also listed among its uses.
Published values
Supplier documentation lists 1,100 cPs viscosity, a 9.5-minute gel time, 33% styrene content and around two-hour cure. These are processing data, not guarantees for a finished casting.

Frequently asked questions
What is Button Grade Resin?
Button Grade Resin is a transparent, semi-liquid unsaturated polyester casting resin. Current Samrat Poly Resins, India documentation lists it for buttons, fashion accessories and small decorative mouldings.
Why is it used for button manufacturing?
Buttons need a resin that casts clear and hard with a fine, polishable surface, since the cast part is the finished product. Button Grade Resin is formulated for that clarity and finish rather than structural strength.
How is it different from general-purpose resin?
General-purpose resin (such as GP Clear Resin) is designed to saturate and bind fibreglass reinforcement. Button Grade Resin is a casting grade used on its own, for clarity, hardness and polishability.
What are the published gel time, viscosity and cure time?
Supplier documentation lists a 9.5-minute gel time, 1,100 cPs viscosity, 33% styrene content and a cure time of around two hours with MEKP catalyst and a cobalt octoate accelerator.
Is it suitable for pigmented casting?
Yes — the supplier lists transparent and pigmented casting work among its uses, alongside buttons and small decorative mouldings.
