Select the resin system before the catalyst discussion
Unsaturated Polyester Resin is a category, while GP Clear, GP White, GP Yellow and Lamination Resin are separate published product routes. The first buyer question is which resin role matches the component, not simply whether an MEKP hardener is required.
Use the relevant product page and current TDS to define the base material, then discuss MEKP as the separate catalyst / initiator component in that documented system.
Keep related FRP roles separate
The resin supplies the matrix role. Glass Fiber is the separate reinforcement material. Gelcoat is the separately selected mould-side surface product, and FRP Polyester Pigment is a separate colour component. A complete requirement identifies each role rather than treating them as one generic FRP material.
Prepare a system-specific quotation
Share the named resin product or family, the intended FRP component, expected quantity, production context if known and delivery location. Review the current MEKP TDS and the base-resin TDS before purchase. Do not transfer process settings from one resin grade to another.
Frequently asked questions
Does this page confirm MEKP for every polyester resin grade?
No. The product pages describe separate grades and roles. Confirm the actual resin product, current data and application before treating a system as appropriate.
What should be included in a polyester-system enquiry?
State the resin grade or product under review, component, expected quantity, process if known and delivery location.
