Plasite 4300 - Vinyl Ester Lining for Aggressive Chemical Tanks

Plasite 4300 is a high-performance vinyl ester lining designed for the most aggressive chemical tank and immersion environments. Combining a vinyl ester resin with a specialized curing system and inert flake pigment, Plasite 4300 delivers outstanding chemical and physical resistance as a thick-film lining for tank service and severe-exposure maintenance coating. Applied in 2 to 3 multi-pass spray coats to a total dry film thickness of 35–45 mils, Plasite 4300 is engineered for long-term immersion service in chemical processing, industrial wastewater, pulp and paper, power generation, and other environments where coating failure is not an option. Color: Grey 0700 Plasite 4300 Product Data Sheet > Here are some key features: Extreme Chemical Resistance: Vinyl ester chemistry provides broad resistance to acids, caustics, solvents, and many aggressive chemical exposures. Ideal for tank linings exposed to chemicals that would compromise epoxy or polyurethane systems. Thick-Film Build: Applied at 35–45 mils total DFT in 2–3 multi-pass coats, providing a robust, pinhole-resistant barrier for demanding immersion service. Thermal & Mechanical Toughness: Continuous dry temperature resistance of 380°F (193°C), non-continuous to 460°F (238°C). Thermal shock tested from -70°F to 200°F and 40°F to 400°F with no adverse effect. Konig Pendulum Hardness of 152 seconds. Coverage Rate: 960 mil·ft²/gal theoretical (field-verified including typical spray loss). Coverage from conventional spray equipment may be approximately 20% lower — plan quantities accordingly. The recommended total system thickness is 35–45 mils, applied in 2–3 coats.
