Introduction: Anodizing Liquid Masking, Plating Liquid Masking

Solvent based MASKANT Polymeric Vinyl peelable Coatings provide protection in two ways; by forming tough, flexible films with extremely low , they stop substrate corrosion caused by electrolytic action or the presence of water-borne oxygen. In addition, the usually thick film provides physical protection against surface damage, abrasion or move and have proven that they provide a high degree of protection against acid and alkali attack.

Plateoff Mask is a liquid chemical maskant used as a stop off for anodizing, chromate conversion coating and other plating on metals. It is fast drying (usually an hour at room temperature) and is resistant to most chemical processes normally required to anodize or electroplate.

It is completely resistant to hot solutions up to 210°F and is tinted blue for better scribe line visibility. The cured film is tack free and will not adhere to itself or other parts.

Plateoff Mask 4210 is a thin viscosity applied by spinning or spray applications. Plateoff Mask 4300 is a thicker, paste-like viscosity applied with a brush or a roller.

Main Advantages

  • Results in a reduction of labor costs.
  • Once cured, it provides an extremely tough, uniform film.
  • Curing time can be cut considerably with the use of heat lamps (100°F), circulation of air and other factors.
  • Easily removed. Peels off in sheets which eliminates messy hand scrapping.
  • Safe, non-flammable.
  • Suitable for plastic and painted surfaces.
