Dudingen, Switzerland – Sika has developed a new polyurethane technology, which it will market under the Purform brand. The company, which specialises in adhesives and sealants for the building and automotive sectors, is initially integrating Purform into its Sikaflex products, and also liquid applied membranes.
Purform prepolymers have ultra-low free monomeric diisocyanate content. The company claims the products have an improved performance profile. Products using the new technology can be extremely weather resistant, and can withstand exposure to UV light outdoors for longer.
Sika has made investments in the associated production facilities at its Dudingen site. It added that the new products are in line with the upcoming stricter Reach regulations in Europe.
