Applications & Use Cases
- ▸ Functions as a tackifying resin in silicone pressure-sensitive adhesives (PSAs), boosting tack and peel adhesion for release liners, tapes, and skin-contact medical/transdermal constructions.
- ▸ Forms a continuous, water-resistant, transfer-resistant film in long-wear color cosmetics (foundations, lipsticks, sunscreens, mascaras), improving wear time and rub-off resistance.
- ▸ Acts as a film former and slip/release additive in topcoats and conformal coatings, delivering a smooth, low-friction, hydrophobic surface finish.
- ▸ Reinforces and structures silicone elastomers, gels, and antifoam compounds by raising resin content and modifying rheology.
- ▸ Imparts a velvety after-feel and durable film in hair styling and skin-care formulations, commonly supplied dissolved in cyclopentasiloxane or other volatile silicone carriers.
