- Little-silicone release agents
Little-silicone release agents. Their demand is increasing especially for electronic devices where silicone can be detrimental. The features and physical properties of LINTEC’s little-silicone release agents are shown below.
Features
- Ideal surface tension that ensures superior resin coatability (water drop contact angle, θ = 70° - 105°)
- High resin coatability (leveling property) and separatability, realizing uniform release performance and improved productivity.
- Available in various formulations with a wide range of release forces from light to heavy release.
Resin coatability test
- The contact angle was measured after dropping 2 µl of pure water on a surface treated with release agent.

- Epoxy resin (10-µm thickness) was applied to a surface treated with release agent, and the surface was checked for repelling and coating unevenness.

- Above figures are measured values; they are not guaranteed.
- Includes those containing a trace amount of silicone.
- *1Acrylic adhesive tape “31B” (Nitto Denko Co.) was attached using a 2-kg roller onto a surface treated with release agent, and the release force was measured 30 minutes later (tape peel; 180-degree peeling at a rate of 0.3 m/min).
- *22µl of solvent was dropped onto a surface treated with release agent, and the static contact angle was measured.
- *3The surface free energy was calculated from the contact angles of pure water, 1-bromonaphthalene and diiodomethane.
