SIKA’S NEW PURFORM® TECHNOLOGY – POLYURETHANE REINVENTED

Sika is bringing a revolutionary new polyurethane technology to the UK sealants and adhesives market with Purform® - a sustainable and high-performance alternative to traditional polyurethane that is clean, durable and reliable.

Purform has been developed by Sika chemists to meet future environmental and health regulations and is both EU REACH and UK REACH compliant which means users will not need to undertake specific training in the future. Purform® technology allows users to benefit from the unique performance attributes of polyurethane at the lowest exposure and the highest level of work safety.

The first UK products to benefit from the ultra-low VOC and low monomer content Purform offers are Sikaflex Pro-3 sealant and Sikaflex 11FC sealant and adhesive.
