Resin release agent

Tadco’s Release agents are high temperature release agent contain no silicon and no ozone depleting substances.

  • Dri-Lube DL 1000 Spray: It provides a protective dry film that stays on the surface to facilitate the release of epoxy resin from plates, pins and bushing. Has a very mild odor. Heat stable up to 260°C (500°F).
  • Tuf-Lube 3C: Versatile and effective water based release agent. Heat stable up to 176°C (305°F). The initial ratio recommendation is 1:4 (Tuf-Lube to water). Comes in bottles of 3.7 L.
