Themecoat 756 FR

Themecoat^® 756-FR is a two component, 1:1 mix, fast cure 100% solids modified aromatic polyurea/polyurethane elastomeric system.

Themecoat 756-FR – Two Component Modified Polyurea Protective Coating

 Themecoat 756-FR is a fast-cure, 100% solids modified aromatic polyurea/polyurethane elastomeric system designed for spray-in-mold applications and as a tough protective membrane. It is used for producing flexible texture skins, protecting flexible foam systems, and waterproofing various surfaces.

·       Two-component system: Side-A (isocyanate) and Side-B (curative), mixed in a 1:1 volume ratio.

·       Requires plural-component spray equipment (minimum 2000 psi) with heated hoses.

·       Agitation of both components is essential prior to and during application.

·       No primer or base coat is specified; this is typically a standalone elastomeric membrane or protective finish.

·       Architectural shapes

·       Decorative elements

·       Encapsulation of fiberglass bodies and polystyrene foams

·       Faux tree bark finishes and other molded textures

·       Application Method: Spray using a mechanical impingement gun (e.g., Gusmer GX7-400).

·       Preheat Temperatures: Components should be preheated to 75–80°F (24–27°C).

·       Hose Temperature: Maintain at 160–170°F (72–77°C).

·       Surface Preparation: Substrates must be free of oil, grease, and other contaminants.

·       Coverage: 1 gallon covers approximately 1600 ft² at 1 mil (wet film).

·       Recommended Build: Apply in multiple thin passes to desired thickness.

·       Pot Life: 2–5 seconds

·       Tack-Free Time: 10–30 seconds

·       Recoat Window: 0–12 hours

·       Temperature Limits: Application is suitable in dry service environments from -20°F to 250°F (-29°C to 121°C).

·       Humidity Sensitivity: Not explicitly stated, but desiccant devices must be used on containers during application to prevent moisture contamination.

·       Storage Requirements: Store above 60°F (15°C); avoid freezing; use wooden pallets and avoid outdoor storage.

·       Shelf Life: 6 months in original sealed containers.

·       Physical Properties:

o   Hardness: 48 ± 5 Shore D

o   Tensile Strength: 1200 ± 200 psi

o   Elongation: 100% ± 20%

o   Tear Resistance: 400 ± 30 pli

·       UV Resistance: Not UV stable – being an aromatic polyurea, it will likely discolor or degrade under UV exposure unless topcoated.

·       Flammability: This is a fire-retardant version (“FR”), though specific fire ratings are not listed.
