Features Of Dow DOWSIL 1-9770 Silicone Release Additive

  1. High-performance silicone-based additive designed to deliver consistent, controllable release in demanding coating and ink systems.

  2. Excellent compatibility with a broad range of waterborne and solventborne acrylics, polyurethanes, and vinyl dispersions.

  3. Enables low migration and minimal surface interference—ideal for applications requiring clean substrate adhesion post-release.

  4. Stable under typical formulation and curing conditions, including ambient drying and moderate thermal cure profiles (up to 120 °C).

  5. Reduces need for post-application silicone wipe-down or rework, supporting improved production efficiency and yield.

Typical Applications Of Dow DOWSIL 1-9770 Silicone Release Additive

  1. Pressure-sensitive adhesive (PSA) release liners for labels, tapes, and medical devices.

  2. Release coatings for flexible packaging substrates, including PET, PE, and paperboard.

  3. Functional coatings in graphic arts and digital printing media requiring temporary or semi-permanent release.

  4. Industrial release layers in composite molding and transfer film applications.
