Mipa P 21 PE resin is a fast-curing laminating resin for reinforced repairs with glass fabric, glass mat or unwoven fibreglass. It creates a strong composite repair layer for larger holes, cracked GRP sections and damaged body panels that need more than filler alone.
The resin bonds well to iron and GRP, which makes it useful both for pure GRP repairs and for mixed repair areas where metal and reinforcement material come together. It can also be used as a joining material when parts are being widened, connected or structurally rebuilt before later finishing steps.
The 1 kg pack with MEKP hardener gives enough working material for focused repair jobs without moving into an oversized bulk container. It suits local body repair, composite reconstruction and reinforcement work where the laminate itself has to carry the repair rather than only support surface finishing.
Used with the correct reinforcement sheet, P 21 builds a dependable repair base that can later be refined with filler and sanding. It is a core material for resin-based repairs that need strength, shape retention and a solid reinforced structure beneath the final surface.
