Sika is recognized world-wide as the market and technology leader for polyurethane sealants and adhesives. Our latest innovation in polyurethanes is the i-Cure® technology. It enables a new generation of sealants and adhesives with significant improvements in workability, durability, adhesion and ecology.
i-Cure® stands for “intelligent cure” and is the chemical base for a new and patent protected crosslinking technology for polyurethane systems. It allows the combination of the best properties of traditional polyurethane sealant and adhesive technology with features such as bubble-free curing and very low emissions. The new products also exhibit unsurpassed adhesion to porous and non-porous substrates. Products based on i-Cure® show that this technology has the potential to improve weatherability and lower the tendency for discoloration when exposed to sunlight, compared to previous polyurethane generations.
By the end of 2010, European Union legislation on chemical safety (directive 67/548/EEC) is adapted to restrict the sales of products containing MDI (methylenediphenyldiisocyanate). The i-Cure® based sealants and adhesives are not affected by the legislative changes; moreover, they are also labeling-free.
Unlike many sealants and adhesives, Sikaflex and SikaBond i-Cure® sealants and adhesives are solvent-free and completely odourless. This allows Sika’s polyurethane products to meet the highest and increasingly stringent emission standards like e.g. AgBB and Emicode EC1 Plus.
