Protective lacquer for electronic circuitry

23 September 2020 Manufacturing / Production Technology, Hardware & Services

APL Acrylic Protective Lacquer is a flexible, fast-drying acrylic conformal coating used for the protection of electronic circuitry. It has been formulated for professional use only and meets the requirements of a variety of international standards. APL can be sprayed, dipped or brushed. The thickness of the coating depends on the method of application (typically 25-75 microns). Temperatures of less than 16°C or relative humidity in excess of 75% are unsuitable for the application of APL. As is the case for all solvent-based conformal coatings, adequate extraction should be used (refer to MSDS for further information). Substrates should be thoroughly cleaned before coating. This is required to ensure that satisfactory adhesion to the substrate is achieved. Also, all flux residues must be removed as they may become corrosive if left on the PCB.

Electrolube manufactures a range of cleaning products using both hydrocarbon solvent and aqueous technology. Electrolube cleaning products produce results within Military specification. We also supply APLSP, which is formulated for professional use only and is supplied to the correct viscosity for selective spray applications. Features include:

• Cost-effective material with fast touch dry time, allowing efficient application processes.

• Good clarity and high level of stability when exposed to UV light.

• Good protection in humid environments and resistance to mould growth.

• Excellent adhesion to a wide variety of substrates.
