Sika’s newly developed polyurethane sealant technology, Purform®, enhances the superiority of polyurethane regarding strength and durability. With a very low monomer content, Sika can manufacture more sustainable products that will meet future environmental and health regulations.  


Purform® technology enables Sika to substantially lower the monomeric di-isocyanate content in its products and to create solutions with content below 0,1%. 


Sikaflex® PRO-3 Purform® masters daily movement for years.

Thus, Sika meets the new European Union REACH regulation, valid since 2023, and adopted to improve the protection of human health and the environment. Users can benefit from the unique performance of polyurethane at the lowest exposure and the highest level of work safety.
