Resins for Direct-to-Metal (DTM) Coatings Strong adhesion, weatherable durability, no primer required
USPA resins are formulated for direct-to-metal (DTM) coatings where corrosion resistance, film integrity and adhesion must be achieved without a primer. Our alkyds, urethanes and plasticizers support coatings used on equipment, containers, infrastructure and fabricated metal parts exposed to weather, wear and industrial environments. We partner with formulators building high-solids, VOC-conscious systems for results on steel, aluminum and galvanized surfaces. Contact us today for more information.
Formulated for Bare Metal Performance
DTM resin benefits include:
- Excellent adhesion to unprimed substrates
- Resistance to rust, peeling and chemical attack
- Fast dry and recoat times to reduce labor cost
- Weatherable film properties for outdoor exposure
- Compatibility with high-pigment and zinc-rich systems
Resin Formulas for a Variety of Metals:
- steel
- aluminum
- galvanized surfaces
- cold-rolled steel
- stainless steel
- galvanized steel
- ferrous metals
- non-ferrous metals
Recommended Resin Systems for DTM Coatings
DTM coating performance depends on adhesion, corrosion resistance and long-term durability without primers. USPA supports various systems with:
- Adhesive Resins – support adhesion across a range of metal substrates in demanding environments
- Coating Resins – alkyds, epoxy esters and polyols for adhesion, film build and weatherability
- Polyester Polyols – essential for 2K polyurethane systems requiring strength and chemical resistance
- Isocyanate Prepolymers– enable durable crosslinked systems for industrial metal protection
Our DTM technologies allow formulators to achieve strong adhesion and protective performance directly on metal substrates.
Industries Using DTM Coatings
DTM coatings are commonly used on structural steel, machinery, tanks, trailers, industrial equipment and fabricated metal assemblies exposed to outdoor or corrosive environments. Our direct-to-metal coating resins are used across industries where corrosion resistance and long-term durability are critical:
Custom Resin Systems for DTM Coatings
We collaborate with private-label and OEM coating brands to build custom DTM-compatible resin blends. Whether you’re upgrading an existing system or developing a new spec, our team helps you align adhesion, flow and durability without added primer layers.
