LORD® HRC-3A/B Heat-Reflective Coating Where To Buy

Product Information

LORD® HRC-3A/B heat-reflective coating is a two-component fluoroelastomer coating which features heat reflectiveness, robust adhesion and exceptional mechanical properties. This coating greatly enhances fuel and fluid resistance for a wide variety of elastomeric substrates.

Application of LORD HRC-3A/B coating on the surface of an elastomeric part allows the bulk of the component to be made of less expensive, less fluid resistant material.

Shelf Life

Shelf life of each component is six months from date of shipment when stored at 21-27°C (70-80°F) in original, unopened container. Do not store or use near heat, sparks or open flame.

Keep the container tightly capped when not in use to prevent solvent evaporation and moisture contamination.

Features and Benefits

Heat Reflective – reflects radiant heat away from the coated parts, enabling parts to operate at cooler temperatures; passes simulated UL 94 V-0 testing.

Easy to Use – prepackaged kit includes coating and curative in the proper mix ratio; cures at room temperature.

Cost Effective – eliminates the need to design parts using expensive elastomers (i.e., silicone); reduces or eliminates the need for heat shields. Resultant system allows engineers to design smaller engine compartments by removing existing heat shields, enabling improved CAFE (Corporate Average Fuel Economy) performance.

Fluid Resistant – provides high temperature, fuel and fluid resistant barrier to external surface of elastomeric part, providing longer life and higher reliability.

Noise Reduction – eliminates rattle produced by loose heat shields.
