Multifunctional Amino Silane Polymer Crosile® 5203
Chemical Properties
Crosile® 5203 is an organosilicon compound amino functional Adhesion promoter.
It can improve the adhesion of hybrid products, RTV solicones, between the inorganic surfaces and some plastic surfaces.
Synonyms
X-203
Specifications
| Test Item | Target Values
(Spec, Limits) |
| Appearance | Slightly Yellowish Transparent Liquid |
| Density (20℃, g/cm3) | 1.0-1.5 |
| Viscosity (25℃、mpa.s) | 1-10 |

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 A1
» Improved adhesion to plastics such as PC and PET
» Improved in elongation and modulus
» Reduced yellowing and reduced staining of transparent end products
