Product Introduction
2K Primer Surfacer is a high coverage automotive primer designed to prepare vehicle surfaces before basecoat and clear coat application. The system uses hydroxyl acrylic resin combined with modified polyisocyanate curing technology to form a durable and uniform underlayer.
The primer is particularly suitable for fast repair operations where strong coverage, quick drying, and easy sanding are required. It helps reduce the visibility of sanding scratches and filler marks while providing a consistent foundation for subsequent paint layers.
After curing, the coating forms a stable film with good hardness and smooth sanding characteristics which improves final surface quality.
