- Improved silicone hold-out
- Good coverage
- Low porosity
- Platinum catalyst compatibility
The Platinum™ product line of fine coating kaolin balances purity, rheology and coverage for silicone release base paper applications such as adhesive labels.
Silicone release base papers are generally used for self adhesive labels. Silicone is applied to the release base paper through a curing process using platinum catalyst. It is vital that the release base paper does not affect this process and mineral purity is extremely important to avoid "poisoning" this process.
The Platinum series of fine coating kaolin are designed to give good coverage and low porosity, thus improving silicone hold-out. Its high purity and chemistry ensure it is compatible with the platinum catalysts used in the siliconization process. The specialized processing minimizes any compounds that can adversely affect the silicone curing process that use platinum catalysts.
We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
