Hempatop Direct 420 improves efficiency and performance

Faster dry-to-touch time

Reduce turnaround times with a coating that  dries in just 45 minutes at 77°F / 25°C, help in increase throughput and reduce production bottlenecks.

Direct-to-metal simplicity

Skip the primer without compromising protection. Hempatop Direct 420 applies directly to steel, saving both time and material costs while maintaining strong adhesion.

Proven corrosion resistance

Tested to ISO 12944-6 for C3-H and C4-M environments, Hempatop Direct 420 provides dependable durability and weatherability in demanding industrial conditions.
Performance. Precision. Protection.

Delivering next-level durability through smart formulation and simplified application

Hempatop Direct 420 is engineered to outperform traditional topcoats with a one-coat, direct-to-metal design that saves time without sacrificing strength. Its water-borne, single-component acrylic technology offers smooth application and excellent resistance to flash rust, UV, and abrasion. The result is a long-lasting, semi-gloss finish that protects against corrosion even in C4-Medium environments. When reliability and efficiency matter most, Hempatop Direct 420 delivers both in one coat.
