MP-233 DTM Primer Surfacer/Sealer is fast drying and easy-to sand. MP-233 was formulated to provide excellent adhesion and corrosion resistance. MATRIX MP-233-Q01 is a low-VOC DTM surface/sealer formulated for use as a primer surfacer in collision repair applications. Mixed at a 4:1:1 ratio by volume, it provides a uniform base coat that prepares aluminum, e-coat, fiberglass, OEM panels, plastic, steel and other primed substrates for subsequent finish coats. The product offers a flash time of 10-15 minutes and a sandable window of 60-90 minutes, allowing rapid progression to sanding and finishing. With an application rate that yields 15-25 coats per quart, it delivers consistent coverage while maintaining low VOC emissions for shop compliance. Safety is governed by a "Warning" signal word; the formulation presents acute toxicity, aspiration hazards, and skin/eye irritation risks. Technicians must wear eye protection, chemical-resistant gloves, protective clothing, and an appropriate respirator, and ensure adequate ventilation during mixing and application. Why Pros Choose Matrix Edge Low VOC MP-233 DTM Primer Surfacer/Sealer is fast drying and easy-to sand. MP-233 was formulated to provide excellent adhesion and corrosion resistance. Application Guide Prepare the substrate: clean, degrease, and remove all loose material; ensure surface is dry and free of contaminants. Mix the product as a primer/surfacer at a volume ratio of 4 parts resin to 1 part hardener to 1 part catalyst. Mix thoroughly until uniform. Apply the first coat with a spray gun or roller, maintaining proper wet film thickness. Allow a flash time of 10-15 minutes before applying subsequent coats. Continue applying additional coats as needed (typically 15-25 coats) to achieve desired build. Each coat can be sanded after the sandable window of 60-90 minutes. After the final coat has reached the sandable time, lightly sand if required and allow the surface to fully cure before any topcoat or finish work.
