Application
Crosile® 5203 has excellent wetting on substrates
It forms weather- and moisture-resistant bonds to substrates which are typically difficult to adhere.
The main benefits in silylated polyurethane or MS polymer adhesives and sealants are:
- Improved adhesion to Al
- Improved adhesion to plastics such as PC and PET
- Improved in elongation and modulus
- Reduced yellowing and reduced staining of transparent end products
