The Techspray 2108-12S is a Turbo-Coat Acrylic Conformal Coating. It is designed to speed up board production throughput without additional investment on expensive UV systems or other capital equipment. It comes in a 12 oz aerosol pray can.
Conformal coating cure time is often considered a production bottleneck for PCB assembly operations. TurboCoat dries tack-free in 3 minutes, allowing manufactures to handle boards in 1/3 the time of the leading acrylic coating. Full cure can be achieved as quickly as 10 minutes with elevated temperatures.
Technology offers a variety of coating formulas to match field and engineering requirements. Specifications generally depent on the type of protection needed: e.g. thermal, moisture, and static resistance. Coatings contain Opti/Scan to allow quality control inspection of coverage and evenness of the coating on a PCB. A coated board can be passed under a standard, low-cost UV (short-wave black) light, and the coated areas glow. The brighter the glow, the thicker the coating.
Instructions: Surface to be sprayed should be thoroughly cleaned with solvent such as Flux Remover G3 (1631). Surface must be completely dry before application of coating. As you spray or brush coating, allow material to flow around components. Coating will be tack free in approximately 5 minutes; however, full cure requires 24 hours depending on humidity and thickness of application. Coated boards can be reworked by applying soldering iron directly to coating, or complete removal can be achieved 1 to 3 hours by using Conformal Coating Remover (2510). Removal time depends on temperature, thickness of coating, and application.
