Frekote 700-NC

Listed price may vary by MOQ. Please contact us for the best price.


Frekote® 700-NC™ offers excellent release properties for the most demanding applications and is a great all-purpose release agent. Frekote 700-NC releases epoxies, polyester resins, thermoplastics, rubber compounds and most other molded polymers.

Specific Benefit

  • No chlorinated solvents
  • High gloss finish
  • High slip
  • No contaminating transfer
  • No mold build-up

Mold Preparation


Mold surfaces must be thoroughly cleaned and dried. All traces of prior release must be removed. This may be accomplished by using Frekote® PMC or other suitable cleaner. Frekote® 915WB™ or light abrasives can be used for heavy build-up.

Sealing New/Repaired Molds:

Occasionally, green or freshly repaired molds are rushed into service prior to complete cure causing an increased amount of free styrene on the mold surface. Fresh or “production line” repairs, new fiberglass and epoxy molds should be cured per manufacturer’s instructions, usually a minimum of 2 -3 weeks at 22°C before starting full-scale production. Fully cured previously unused molds should be sealed before use. This can be accomplished by applying one to two coats of an appropriate Frekote® mold sealer, following the directions for use instructions. Allow full cure of the appropriate Frekote® mold sealer before you apply the first coat of 700-NC™ as outlined in the directions of use.

Directions for use:

  • 700-NC™ can be applied to mold surfaces at room temperature up to 135°C by spraying, brushing or wiping with a clean lint-free, cloth. When spraying ensure a dry air source is used or use an airless spray system. Always use in a well ventilated area.
  • Wipe or spray on a smooth, thin, continuous, wet film. Avoid wiping or spraying over the same area that was just coated until the solvent has evaporated. If spraying, hold nozzle 20 to 30cm from mold surface. It is suggested that small areas be coated, working progressively from one side of the mold to the other.
  • Initially, apply 2 to 3 base coats allowing 5 to 10 minutes between coats for solvent evaporation .
  • Allow the final coat to cure for 15 to 20 minutes at 22°C.
  • Maximum releases will be obtained as the mold surface becomes conditioned to 700-NC™. Performance can be enhanced by re-coating once, after the first few initial pulls.
  • When any release difficulty is experienced, the area in question can be “touched-up” by re-coating the entire mold surface or just those areas where release difficulty is occurring.
  • NOTE: 700-NC™ is moisture sensitive, keep container tightly closed when not in use. The product should always be used in a well ventilated area.
  • Precaution: Users of closed mold systems(rotomolding) must be certain that solvent evaporation is complete and that all solvent vapors have been ventilated from the mold cavity prior to closing the mold. An oil-free compressed air source can be used to assist in evaporation of solvents and ventilation of the mold cavity.

Mold Touch up

Touch up coats should only be applied to areas where poor release is noticed and should be applied using the same method as base coats. This will reduce the possibility of release agent or polymer build-up. The frequency of touch ups will depend on the polymer type, mold configuration, and abrasion parameters.
