TIER Coat is a mold release film developed by Toadenka for plastic molding metal molds. It allows for molding of highly adhesive resins, such as clear epoxy resin, without using mold release agents by forming a fluorine nano scale film through vacuum deposition. It also displays superior release performance for silicon resins, urethane resins, and other adhesive resins.

<<TIER Coat Applicable Fields>>
Because the product is a thin film with film thickness of approximately 30 nm, it causes no damage to even microscopic shapes as in processing involving metal molds for microlens formation. It is expected to use in cutting edge fields, such as, in metal molds for mobile phone and handheld game optical films and metal molds for optical discs and microlenses.

<<TIER Coat Major Characteristics>>
The film has high durability due to strong adhesion through chemical bonding and has a proven track record in over 150,000 shots for thermoplastic resin molding.
Possessing a thin, film thickness of 30 nm, allows for drastic improvements in production efficiency and product yields compared to older methods involving application of mold release agents for each molding process.
It also possesses superior water repellent properties, making it effective at preventing stain as well. Since recoating is possible, the product also allow for molds to be reused.

<<TIER Coat Physical Properties, etc.>>
1. Film thickness: Approx. 30 nm
2. Contact angle: Ethanol 55-60°
3. Solvent resistance: There was no decrease in release performance after immersion testing in the following solvents.
n-hexane, cyclohexane, isopropyl alcohol, ethanol,
xylene, diethyl ether, tetrahydrofuran,
acetone (Testing conditions: Immersed for 360 hours at room temperature)
4. Metal mold materials on which film formation is possible:
Iron materials, stainless materials, chrome plating, electroless nickel plating
Electrical nickel plating (electroformed nickel)
5. Mold temperature at time of molding: -250ºC
*TIER Coat is an organic film so it will be damaged if rubbed with hard items (metal, glass filler, etc.), losing its effectiveness.
