Introduction: Plastic Thermoforming Masking
Water based peelable protection for Helicopter, Temporary Protective Peelable coating for Helicopter Acrylic Windows, Aircraft Windshields
Helicoat 1170 is a water based coating that upon water evaporation becomes clear/ transparent. The coating has no solvents to damage the surface. The clear cured film has excellent cohesion in snow, wind and speeds exceeding 85 mph. Helicoat 1170 is milky when wet and clear when all the water is evaporated. The clear film is transparent and cures upon water evaporation. The coating on dry, warm, sunny days can dry within 30 minutes. This same coating on humid days will take much longer to cure. Apply the coating, a minimum of 10 mils of wet film. Performance statements are based upon representative experience from testing throughout the United States; however, actual performance will be determined by substrate, preparation, exposure conditions and maintenance.
HeliCoat 1170 is VOC free with water being the only vapor released during the curing process. HeliCoat is applied via airless or air assist sprayer. HeliCoat peelable coating is non flammable and non combustible as supplied and when the dry strippable film is formed and is also low hazard (see separate Health & Safety Data).
HeliCoat 1170 is a water resistant, peelable temporary protective that air dries quickly, leaving a tough, clear flexible coating that is easily removed from a variety of surfaces. HeliCoat 1170 represents the ultimate in waterborne removable coating technology.
Description: 1170 is a water based masking compound that forms a tough clear plastic film with controlled adhesion to plastics to give excellent surface protection and easily strippable. It is designed to apply on flat sheets of plastic prior to thermoforming. It is engineered to be sprayable as masking film for heat forming and decorating acrylic, polycarbonate and Abs sheets.
The clear film of HeliCoat 1170 once dry can be run through the full process cycle of thermoforming with the part with any shape of part and with the dry film in direct contact with die. The dry peelable film of 1170 remains dry and tack free even while hot. When coarse material or very tight dies are being coated talc or powder dusting may help. Application and dry film of 1170 allows full protection of the plastic sheet from the time is inspected in the flat through forming and fabrication process such as drilling, routing, sheeting, etc.
Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or “film” when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that it can be stretched into or onto a mold and cooled to a finished shape.
