Sikafloor® PurCem® HB-21

LIGHT TEXTURED, BROADCAST, MATT FINISH POLYURETHANE CEMENT HYBRID FLOORING SYSTEM

Sikafloor® PurCem® HB-21 system is made with polyurethane cement technology and is part of the Sikafloor® PurCem® flooring range. Due to its defined surface texture the Sikafloor® PurCem® HB-21 system is especially designed for areas where increased safety level against slipping is required. It is designed to withstand chemical attack and high impact and can be used in wet and dry processing plants.
The system consists of a highly durable polyurethane cement body coat, broadcast with fine aggregates for increase slip resistance and sealed with a pigmented top coat making the system easy to maintain. Suitable for use in hot and tropical climatic conditions.
