Acrylic Conformal Coatings

Acrylic coatings are easily and quickly removed by a variety of solvents often without the need of agitation.

Acrylic conformal coatings.

Acrylic resin conformal coating currently makes up 80 of the market. Acrylic coatings dry rapidly are fungus resistant and provide long pot life. Typically applied at 25 250 μm micrometers thickness it is applied to electronic circuitry to protect against moisture dust chemicals and temperature extremes. Using printed circuit boards as an example conformal coatings lower the necessity to hermetically seal a board and the board is more reliable to function properly in humid environments.

Conformal coating material is a thin polymeric film which conforms to the contours of a printed circuit board to protect the board s components. This extremely effective acrylic conformal coating provides a hard durable protective barrier against humidity salt corrosive vapors and fungus for printed circuit board and electronic assemblies. Acrylic conformal coatings are perhaps the most popular of all conformal coating materials as they are easy to apply and remove with a wide process window for use. There are many benefits with using conformal coating.

While they share the same methods of applications and ultimate end item uses there are some differences that should be addressed prior to deciding what conformal coating is the best for your project. Konform ar acrylic conformal coating konform ar is ideal for providing insulation against high voltage arcing and corona shorts. 419c acrylic conformal coating is an ipc cc 830b and ul 94 v 0 certified fast drying xylene and toluene free product. Acrylic conformal coating is recognized for its high dielectric strength and fair moisture and abrasion resistance.

What generally distinguishes acrylic coating from other resins is ease of removal. Acrylics dry and cure rapidly reaching optimum physical properties in minutes and full cure in less than hour. This one part coating provides an excellent finish is easy to use and does not require special or costly equipment to apply. It is ideal for high moisture environments and applications requiring easy repair and rework.

Additionally acrylic materials produce little or no heat during the curing process eliminating. There are many reasons for this. Coatings can be applied in a number of ways including brushing spraying. Humiseal 1b31 is a fast drying single component acrylic conformal coating that provides excellent moisture and environmental protection for printed circuit assemblies.
