Pan-Grip and Pan-Grip Flex

Pan-Grip and Pan-Grip Flex are multicomponent novolac based epoxy products that are  designed to seal and repair corroded surfaces in all HVAC systems. The products can be used on horizontal and vertical surfaces. The coating is impervious to water, non-rusting, chemical resistant, and can be applied directly to a properly cleaned and prepared surface without a primer. 

Pan-Grip can be applied and will cure under water. Pan-Grip Flex is designed for high elongation in typical environments and for applications where vibration and movement will be of concern. It is able to withstand moisture, manage temperature changes, and adjust from freeze to thaw.
