Protecting Personnel

Heat-Flex 3500 is a multipurpose insulative acrylic coating for industrial systems that enables dangerously hot systems like piping and ductwork to stay cool to the touch, preventing burns and protecting the safety of workers.

Plant owners and operators looking to enhance employee safety while also minimizing corrosion under insulation (CUI) risks can turn to a new insulative acrylic coating designed for both personnel protection and mitigating CUI.

Heat-Flex® 3500 is a multipurpose insulative acrylic coating for industrial systems that enables dangerously hot systems like piping and ductwork to stay cool to the touch, preventing burns and protecting the safety of workers.

What is unique about this insulative coating is that it can be applied directly to ambient or hot surfaces up to 350° F (177° C), offering plants the flexibility to reduce downtime by keeping systems online during coating and recoating applications. In addition, Heat-Flex 3500 also insulates hot and cold surfaces, helping industrial processes retain heat and performs under cyclic thermal shock conditions.

The insulative and anti-corrosive properties of Heat-Flex 3500 enable plant owners to eliminate concerns related to CUI on the exterior of piping, ductwork, and other surfaces wrapped in conventional insulation and cladding. The coating also prevents radiant solar heating.

Heat-Flex 3500 coating is ideal for everything from pipes, valves, tanks, vessels, heaters, and boilers to compressors, pumps, containers, stacks, and ductwork that operate in temperature ranges between -80° F and +350° F.

The product goes on fast and easy to save application time and costs. Its single-component, waterborne acrylic formulation can be applied with standard airless equipment. Its very fast dry time allows for recoating within two hours. Heat-Flex 3500 coating minimizes overspray risks with droplets drying to a non-adhering dust within a 20-foot fall.
