Acrylic Conformal Coating

Acrylic resins ar are preformed acrylic polymers that are dissolved in a solvent and used to coat a pcb surface.

Acrylic conformal coating.

This is the most used conformal coating for pcbs. Hpa is a high performance acrylic conformal coating specifically designed to meet the demanding requirements of applications such as the defence and aerospace industries. Acrylic coatings are easily and quickly removed by a variety of solvents often without the need of agitation. Whenever it faces even stronger solvents it will not offer the protection that is needed especially if your product is a mission critical device.

Acrylic conformal coating is recognized for its high dielectric strength and fair moisture and abrasion resistance. The acrylic conformal coating is applied by using a hand brush sprayed or dipping the board in an acrylic resin coating. 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. Konform ar is ideal for providing insulation against high voltage arcing and corona shorts.

Sr provides good chemical resistance moisture and salt spray resistance and is very flexible. The methacrylate copolymer resin offers excellent resistance to water alcohol dilute acids alkalis chemical fumes and corrosive or oxidizing environments. Aromatic free acrylic coating film coat acrylic conformal coating formulated especially for use with selective coating machines using non atomised film coat applicators. Silicone resin sr silicone conformal coating provides excellent protection in a very wide temperature range.

Konform ar resin meets mil i 46058c type ar. 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 coating gel designed for use with the afa range as a permanent masking or damming material or for coverage of sharp edges. What generally distinguishes acrylic coating from other resins is ease of removal.

Conformal coating material is a thin polymeric film which conforms to the contours of a printed circuit board to protect the board s components. Konform ar acrylic conformal coating is easy to use offers great protective properties and is ipc cc 830b and ul certified. Hpa is fast drying and flexible while maintaining excellent characteristics in the most challenging of environments. This webinar will report the test method and performance evaluation results of acrylic silicone and atomic layer deposition conformal coatings.
