STABLE SILICONE-COATED RELEASE LINER FOR PRESSURE- SENSITIVE ADHESIVE SHEETS |
摘要 |
<p>Silicone-coated release liner which, even after exposure to light in the presence of moisture, heat or both, displays release properties of less than 20 g/cm width with respect to pressure-sensitive adhesive tape. The coating contains noble metal, and the silicone polymer has substantially no residual ethylenic unsaturation. The silicone polymer is prepared by pre-reacting polydimethyl siloxane with a noble metal catalyst before adding polymethylhydrosiloxane crosslinker.</p> |
