Technical Specifications

  Selection and Specification Data
Product Name Mascoat Marine Thermal Insulation Coating
Product Number DTM GEN2
Generic Type Water-based Acrylic Marine Insulation Coating
Description Mascoat Marine is a multi-purpose coating that provides thermal insulation and anti-condensation protection. It combines painting and insulating solutions for marine vessels and provides drastic reduction in temperatures for its thickness
  • IMO/SOLAS compatible
  • MED certification
  • Provides anti-condensation protection
  • Dramatically reduces heat absorption due to radiant heat gain
  • Excellent personnel protection
  • Easy application characteristics
  • Applies to almost any surface
  • Extended recoat window
  • Fast drying and curing rates
  • No harmful volatile organic compounds
Gloss Flat
Color White and Light Grey. Custom tinting can be done at special request.
Priming Self-priming over non-ferrous materials (stainless steel & aluminum). Primers are required for carbon steel substrates.

Limitations Applications should not exceed 225oF (107oC) or peak areas above. Do not subject wet coating in pail format to freezing conditions.
  Substrates & Surface Preparation
Surface Prep Surface should be dry and free of foreign matter. Surface prep can be used to NACE 1-3 (SSPC SP 5-6) when applicable.
Ferrous Surfaces Should be primed prior to application of Mascoat Marine. Since the coating is water-based, it is important to have a boundary layer of protection to eliminate flash rusting.
Non-ferrous Surfaces The coating can be applied directly to non-ferrous surfaces. Surface should be clean and free of oil, dirt or any other foreign matter.
  Application Equipment
Airless Sprayer
Pump Ratio: 33:1 or larger
Volume: 1.5 gpm (5.6 lpm) or greater
Hose: 3/8″ or larger with no more than 3′ of 1/4″ whip. 1/2″ hose recommended for length above 50′;
Top Size: .017″ (for tight spots)
.019-.023″ (for normal use)
Pressure: Minimum of 3000 PSI
Small Spray Application Please consult Mascoat for the sprayer. This gun is excellent for small applications & touchups.
Brush Brushing is only recommended for touchup of less than 0.5 ft2 (0.04 m2). Brushing can inhibit coating performance. Please consult Mascoat for detailed instructions regarding brushing.
Roller Not recommended for this coating.
  Application Equipment
Surface temperatures for applications should be 60oF (15oC) or above. Lower surface temperatures will increase dry times.
Applications Ambient & Cold (60o-139oF, 15o-59oC): For temperatures (surface or ambient - whichever is lower), an initial tack coat is recommended of 10 mils (0.25 mm or 250 microns). This tack coat will help to eliminate sag on vertical wall applications. Tack coat should be dry to touch prior to next pass. Typlical coat thickness should not exceed 20-22 mils (0.50-0.55 mm) wet. Coating can be reapplied after each coat is thoroughly dry.

Hot (>140oF, >60oC): Application of Mascoat Marine should be applied as per Mascoat detailed hot application instructions.
Application Thickness Product can be applied in successive coats to increase insulation abilities.
Forced Ventilation Forced ventilation should be used to help coating dry and hang on vertical surfaces. Air movement should be both in/out during drying process.
Dryfall Dryfall within a 3 ft. radius.
