AMBERSIL ACRYLIC CONFORMAL COATING is a transparent - quick drying -insulating and protective coating based on acrylic resins.A low viscosity - solvent-drying acrylic based conformal coating with excellent insulating properties. The lacquer is transparent and flexible. It has a durable adhesion in the temperature range from 40C to +60C and can be used for a short period of time up to +100C maximum. It protects printed circuit boards and surfaces from humid inorganic acid or caustic vapours.
APPLICATIONS
Specially developed to protect printed circuit boards. It prevents electrical leakages and short circuits.As a low viscosity fixing and insulating lacquer - Acrylic Conformal Coating can also be used as extra/after insulation of coils and transformers and reduces operational noise.
DIRECTIONS
Spray from a distance of 20 to 30 cm on the dry and degreased surface. Pre-cleaning of PCBs is recommended (use Ambersil PCB Cleaner) to remove greases - dirt and flux residues (Ambersil Flux Remover). When finished spraying - clear the aerosol valve by turning the can upside down and pressing the button until only propellant escapes.Printed circuit board materials and electronic components generally have a good compatibility with this coating. In case of plastic surfaces (e.g. housings) a compatibility test is always recommend. It is advisable to test its suitability for plastics susceptible to stress cracking (e.g. polycarbonate).Contains flammable solvents and hence when working with the product - make sure there is good ventilation in the workplace. Remove all possible ignition sources.For automatic application - or if a lower viscosity is required; Ambersil Acrylic Conformal Coating Thinners can be added.

NOTE:Ambersil Acrylic Conformal Coating Thinners also available - standard hydrocarbon solvents for use with Ambersil Acrylic Conformal Coating. Thinners reduce viscosity and allow for an even and thorough application.Dilute as required to attain required viscosity. Particularly useful in automatic applications.
STORAGE
The product may be stored at normal ambient temperatures and has a shelf life of not less than 72 months with correct storage. Aerosols should always be stored below 50OC - away from direct heat and naked flame.
