Sikcoat™ RCA20 is an organosilicon polysiloxane designed for use as a heavy release force regulator in solvent-free, addition-curing silicone release systems. It offers stable performance with minimal impact on residual adhesion, and provides consistent adjustment of peeling force.
Easy to incorporate.
Effective adjustment of release (stripping) force.
Minimal influence on residual adhesion.
Stable aged release performance.
Appearance | Colorless to slightly hazy liquid |
Active Content (%) | 98-100 |
Viscosity (cP, 25°C) | 700-1,400 |
Density (g/cm3, 20°C) | 1.01 |
These values are typical and are not intended for use as specifications.
Sikoat™ RCA20 is used as a release control additive in solventless Sikcoat release systems, functioning via polyaddition curing. It can be substituted for 1% to 100% of the base polymer in a solventless system to adjust release force.
Sikoat™ RCA20 enables stable modulation of peel force over time, low "zipping" tendency, and compatibility with double-sided coating without blocking. It is especially effective in systems requiring higher release values with acrylic or rubber-based adhesives, and can be used in both in-line and off-line coating operations.
Sikoat™ RCA20 is available in 200kg Drum or 1000Kg IBC.
When stored in original unopened containers at temperatures below 35°C, Sikoat™ RCA20 has a shelf life of 6 months from the date of production.
