Ionomers are polymerized through copolymerisation of a nonpolar with a polar monomer. The polar linkage push back crystallization and cause a ionic cross linking.
Our special adhesive powders based on Ionomers provide particularly following properties:
- resistance against acids, bases, fats, oils and solvents
- no electric conductivity
ROWALIT® Ionomer is successfully used in the automotive industry.
