GLYPTAL® 1201 Red Insulating Enamel is a versatile industrial coating developed to insulate, seal and protect electrical components, metal surfaces and industrial equipment. Its durable, low-gloss red film adheres to materials including metal, ceramic, porcelain, concrete, fiber and wood.
Originally designed for coating electrical coils and armatures, GLYPTAL 1201 also provides dependable protection against moisture, corrosion, oil, salt water, mild acids, heat, dust and abrasion. It can be used as an electrical insulating coating, industrial primer, protective finish, concrete sealer, gasket adhesive or thread sealer.
The enamel is supplied ready for brush application and may be thinned appropriately for spraying. It becomes dust-free in approximately 30 minutes and can be handled after approximately two hours under typical conditions.

Application Information
Surfaces should be clean, dry and free of oil, dust, rust and other contaminants before application. Apply by brush as supplied or thin with an appropriate compatible solvent when preparing the coating for spray application. When multiple coats are required, allow adequate drying time between applications.
Test the product on the intended substrate and under actual service conditions before beginning a full production application.
Safety and Handling
GLYPTAL 1201 is a highly flammable solvent-based coating. Use it only outdoors or in a well-ventilated work area and keep it away from heat, sparks, open flames and other ignition sources. Wear appropriate gloves, protective clothing and eye protection. Avoid breathing vapors or spray mist and consult the current Safety Data Sheet before use, storage, transportation or disposal.
