At ADIRAJ COATING PVT. LTD. (Adiraj Enterprises), our state-of-the-art powder coating process ensures 100% even coverage, flawless wrap-around, and long-lasting durability. Located in Chakan, Pune, we serve automotive Tier-1 suppliers, heavy equipment manufacturers, electrical switchgear firms, and precision engineering fabricators across Maharashtra.
Unlike conventional solvent-borne paints, thermoset powder coating involves zero volatile organic compounds (0% VOC), delivering an environmentally compliant, dense polymer shield that is virtually immune to chipping, scratching, hydraulic fluid corrosion, and outdoor ultraviolet degradation. With our disciplined 7-9 tank pre-treatment line and calibrated convection bake ovens, we guarantee maximum molecular adhesion and corrosion barrier properties meeting exacting automotive OEM standards.
Comprehensive alkaline degreasing, derusting, water rinsing, surface activation, and zinc phosphating for optimum bond strength.
Calibrated electrostatic charging ensures superior wrap around complex geometric welds, deep louvers, and sharp edges.
Digitally monitored convection ovens maintain 180°C to 200°C metal temperature for complete polymer cross-linking.
Pure Polyester, Epoxy-Polyester Hybrid, and Pure Epoxy formulations in smooth gloss, satin, matt, texture, and wrinkle finishes.
