NEXT GENERATION, THERMAL INSULATIVE COATING

Page last modified
August 29 2025

HEAT-FLEX® 7000 is a one component thermal insulative coating system that offers personal protection, solar heat reflectivity
and resultant insulation capabilities for an array of industrial applications. This single-component, spray-applied coating
system meets Occupational Safety and Health Administration standards for protecting personnel from skin-contact burns
on assets operating at temperatures up to 350°F (177°C) in one coat applied at 1250 microns.


A single coat can eliminate the costs of installing, inspecting and repairing conventional insulation and cladding systems
for personnel skin-contact protection, thereby also eliminating the common threat of corrosion under insulation (CUI).
In addition, the coating reduces heat loss enabling process stability.

 

HIGHLIGHTS
• Single component so therefore no requirement for difficult mixing guidelines
• Simple single-coat application
• High build film thickness
• Low thermal conductivity
• Use in indoor or outdoor environments
• Protects against radiant solar heat gain
• 75 percent volume solids formulation
• <50 g/L VOC
• Can be used with ISO 12944 prequalified schemes/systems C3-CX

 

INDUSTRY APPLICATIONS

• Tanks
• Piping
• Vessels
• Furnaces
• Stacks
• Offshore Assets/Marine
• Containers
