Different roles, not competing names
The key difference is role. Samrat Poly Resins publishes Lamination Resin for lamination and FRP bonding work, and GP Gelcoat Resin as a mould-surface coating. A useful FRP discussion separates the laminate or bonding requirement from the finished surface requirement.
When to review Lamination Resin
Review Lamination Resin where the published application concerns door lamination, plywood lamination, FRP bonding or clear-finish hand lay-up work. Check the actual substrate, reinforcement, working conditions and product TDS before selection.
When to review Gelcoat Resin
Review GP Gelcoat Resin when the question is about the mould-facing surface. It should be selected against the required finish and the appropriate product data, rather than being used as a generic substitute for a laminate resin.
What to include in an enquiry
Share the component, manufacturing sequence, mould or surface requirement, substrate or reinforcement, quantity and delivery location. This lets the team discuss the correct product role without assuming the process.
