Silicone Resins (siblings)
Silicone Release Liner Coating
Silicone release coatings are ultra-thin (0.5–2 g/m²) cured films applied to paper, polyethylene, or PET film substrates to provide controlled release of pressure-sensitive adhesive labels, medical products, food packaging, and industrial tapes. MQ resin blended with PDMS in addition-cure or condensation-cure systems is the dominant formulation.
Specifications
| Coat Weight | 0.5–2.0 g/m² (dry) |
| Release Force | 10–500 mN/25mm (tunable via M:Q ratio and cure) |
| Subsequent Adhesion Retention | >90% (TLMI, PSTC) |
| Cure System | Platinum addition-cure (120–150 °C) or tin condensation |
| Substrate | Glassine, kraft, PE, PET, polypropylene |
Applications
- Label release liner (self-adhesive labels, barcode labels)
- Medical release liner for wound dressings and surgical drapes
- Food-contact parchment and baking paper (FDA compliant)
- Industrial double-sided tape carrier and liner
- Electronics protective film release surface
Key Features
- Tunable release force across 3 orders of magnitude (10–500 mN/25mm)
- No silicone migration — premium grades retain >90% subsequent adhesion
- Platinum-cure enables fast line speed (≥300 m/min) at 150 °C
- FDA 21 CFR 175.300 compliant for food-contact liner applications
