Sikoat™ RC500 is a reactive siloxane base polymer designed for use in solvent-free, addition-curing silicone release coating systems. When combined with the appropriate crosslinker and platinum catalyst, it provides stable release performance with low peel force and fast curing. It is mainly developed for paper and film release liner applications.
100% active, solvent-free base polymer
Consistent and controlled release force
Low peel force, stable even after aging
Excellent anchorage on paper and film substrates
Low silicone migration, wide substrate adaptability
Appearance | Colorless clear liquid |
Density (20°C) | 0.96-0.99 |
Viscosity (cP, 25°C) | 300-400 |
Initial release force (g/in) | 5-7 |
Aged release force (g/in) | 9-13 |
These values are typical and are not intended for use as specifications.
Sikoat™ RC500 is used as release coating base polymer for:
Release papers for pressure-sensitive adhesive tapes and label stock
High-speed adhesive tape base coatings
Industrial single- and double-sided release papers and films
Anti-stick and anti-adhesive packaging applications
Sikoat™ RC500 is available in 200Kg Drum or 1000Kg IBC.
When stored at temperatures below 35°C in the original unopened containers, Sikoat™ RC500 has a shelf life of 12 months from the date of production.
