Quick facts
- Button Grade Resin
- Unsaturated polyester casting grade for buttons and small decorative mouldings
- Clear Casting Resin
- Two-part epoxy system for decorative and clear casting
- Cure approach
- Different product systems with separate published cure information
- Selection rule
- Do not substitute by the word 'casting' alone
Casting is a role, not one chemistry
The phrase casting resin does not establish that two products have the same chemistry or process. Samrat FRP Traders publishes Button Grade Resin as an unsaturated polyester grade for buttons and small decorative mouldings. Clear Casting Resin is a separate two-part epoxy system for decorative and clear casting applications.
A buyer should therefore start with the required resin system and finished component, not the broad word casting.
Compare the published cure systems
Button Grade Resin is listed with an MEKP and cobalt octoate system, 9.5-minute gel time and approximate two-hour curing time. Clear Casting Resin is listed as a 2:1 resin-to-hardener system with 24-hour initial cure and 72-hour full cure. These are separate published instructions and must not be interchanged.
Exact procedures, safety requirements and suitability should be taken from the relevant TDS and approved process documentation.
Frame the right selection question
For a button or small decorative moulding requirement, Button Grade Resin is the relevant published starting point. If a drawing, customer specification or trial calls for an epoxy system, review Clear Casting Resin as a separate product and confirm it against the application rather than assuming it is an equivalent substitute.
Procurement information to provide
Share the intended part, required resin system if specified, appearance requirement, process method, expected quantity and delivery location. This enables a product-specific discussion without an unsupported performance promise.
Published product-system comparison
| Decision factor | Button Grade Resin | Clear Casting Resin |
|---|---|---|
| Resin system | Unsaturated polyester | Two-part epoxy |
| Published role | Buttons and small decorative mouldings | River tables, jewellery and decorative casting |
| Published cure information | MEKP and cobalt octoate system; 9.5-minute gel time; approximately 2-hour cure | 2:1 mix by weight; 24-hour initial cure; 72-hour full cure |
This is a product-role comparison, not a performance ranking. Review the exact TDS and the intended part before selecting either system.
