CONFORMAL COATING, Acrylate Coating for Electronics
Humiseal Type 1B73, mfg by Chase Corp.
This forms a thin film that seals electrical and electronic components and circuits against water and dirt and corrosive atmosphere. It doesnt really waterproof electronics, but it can make them a lot better at resisting water because it is nearly impossible to achieve 100% coverage. It is best to avoid using this on the majority of heat sink surfaces.
Price: $8.00/ 11.5 oz metal spray can (Typically retails for $22 to $30/ can) (Indiana 7% sales tax where applicable)

Shipping: ORM-D, extremely flammable. humiseal.com => Acrylic resin conformal coatings are perhaps the most popular of all conformal coatings due to their ease of application, removal and forgiving nature. Acrylics dry rapidly, reaching optimum physical properties in minutes, are fungus resistant and provide long pot life. Additionally, Acrylics give off little or no heat during cure eliminating potential damage to heat-sensitive components. They do not shrink during cure and have good humidity resistance and exhibit low glass transition temperatures. Acrylic resin coatings are easy to apply and can be easily removed for rework using solvents. Spot removal of the coating to repair a solder joint or replace a component can be easily accomplished by localized solvent application. Although not encouraged, Acrylic coatings can be soldered through if preferred. HumiSeal 1B73: Fast drying, clear acrylic. Air dries to a hard, yet flexible film. Cured coating may be soldered through leaving no residue. Contains UV tracer. UL recognized. Qualified to MIL-I-46058C
1B73 Description: An acrylic coating characterized by a higher tack resistance at elevated temperatures not normally associated with thermoplastic
materials. Has excellent electrical properties and flexibility. This coating is also available in AEROSOL CANS.
