Little-silicone release agents

Print

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.

    【Silicone release agents】

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

    【Little-silicone release agents】

    High surface tension and superior resin coatability reduce the chance of repelling or coating unevenness.

    【Silicone release agents】

    Low surface tension and inferior resin coatability increase the chance of repelling and coating unevenness.

  • Above figures are measured values; they are not guaranteed.
  • Includes those containing a trace amount of silicone.
  1. *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).
  2. *22µl of solvent was dropped onto a surface treated with release agent, and the static contact angle was measured.
  3. *3The surface free energy was calculated from the contact angles of pure water, 1-bromonaphthalene and diiodomethane.
