BioThane Hardener

ProSPARTIC Hardener is the isocyanate component used in the ProSPARTIC polyaspartic system, typically mixed at a 1:1 ratio with either ProSPARTIC S-Resin or F-Resin. It contributes to fast-curing performance, excellent UV stability, and exceptional chemical and abrasion resistance. The resulting film performs well under heavy foot and vehicle traffic, even in environments with high moisture or temperature variation. ProSPARTIC Hardener enables a quick return-to-service and long open working time, making it ideal for commercial kitchens, garages, and retail spaces. It supports both clear and pigmented applications, allowing seamless finishes in decorative or industrial systems.
