REX-HT is a post set expansion additive developed for use at temperatures above 170°F (76.7°C). REX-HT additive helps control microchannels, which provide a pathway for interzonal communication. The expansion provided by REX-HT additive develops as a function of temperature, which accelerates expansion.

Features and Benefits

• Performs well in areas with suspected micro channeling problems with minimal design and job execution problems
• Non-hazardous in normal working conditions
