Acrylic Conformal Coatings

Typically applied at 25 250 μm micrometers thickness it is applied to electronic circuitry to protect against moisture dust chemicals and temperature extremes.

Acrylic conformal coatings.

Acrylics dry and cure rapidly reaching optimum physical properties in minutes and full cure in less than hour. There are many benefits with using conformal coating. Acrylic resin conformal coating currently makes up 80 of the market. Additionally acrylics give off little or no heat during cure.

Acrylic conformal coating is recognized for its high dielectric strength and fair moisture and abrasion resistance. Konform ar acrylic conformal coating konform ar is ideal for providing insulation against high voltage arcing and corona shorts. 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.

Conformal coating material is a thin polymeric film which conforms to the contours of a printed circuit board to protect the board s components. Additionally acrylic materials produce little or no heat during the curing process eliminating. Acrylic coatings dry rapidly are fungus resistant and provide long pot life. What generally distinguishes acrylic coating from other resins is ease of removal.

Acrylic coatings are easily and quickly removed by a variety of solvents often without the need of agitation. 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. 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. This one part coating provides an excellent finish is easy to use and does not require special or costly equipment to apply.

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 reasons for this. It is ideal for high moisture environments and applications requiring easy repair and rework. Acrylic conformal coatings are most user friendly of all conformal coating materials due to their ease of application removal and repair through coating.
