Chryso®Optec EC-925 (formerly OPTEC EC 925)

Chryso®Optec EC-925 is an innovative admixture specifically formulated to enhance the overall appearance of hardscapes and architectural concrete masonry units. Chryso®Optec EC-925, is a unique blend of novel ingredients that help improve and retain color vibrancy by controlling both primary and secondary efflorescence. Chryso®Optec EC-925 also contains a “slip” ingredient that aids in workability and provides a smooth modest swipe texture on the surface of the unit.

Chryso®Optec EC-925 may be used in hardscapes such as concrete pavers, concrete slabs and segmental retaining wall units. Other uses where improved aesthetics are desired include architectural block, concrete brick, manufactured stone veneer and cast stone units. Chryso®Optec EC-925 is designed to reduce both primary and secondary efflorescence, while maintaining unit physical properties.
