Start with the component role
An epoxy resin is the resin component. Epoxy Hardener is the separately published curing-agent component selected to work with a compatible epoxy resin system. Their names describe different roles, even when both appear in the same commercial discussion.
This distinction matters for purchasing: a hardener is not a replacement for the resin, and a resin is not a confirmation of which hardener should be used. The exact published pairing needs review before procurement.
A matched system is more useful than a generic label
Samrat's Clear Casting Resin and Epoxy Art Resin product routes each identify a compatible Epoxy Hardener as part of their separately published two-component systems. That published relationship is more useful than assuming any product called epoxy or hardener can be combined.
The relationship does not establish universal compatibility with other epoxy products, suppliers or applications. Review the product-specific TDS and ask for confirmation when the component, product route or documentation requirement differs.
Keep the enquiry focused
State the exact epoxy resin product under consideration, intended application, quantity, packaging need, delivery location and any technical-document requirement. If the requirement comes from a drawing, purchase specification or existing system, include that reference when available.
This guide intentionally does not provide ratios, calculations, mixing steps or cure schedules. Those are product-system instructions that must remain in the appropriate current documentation. Both halves of the pair are published together in the epoxy systems we manufacture, each with its own technical data sheet.
