PCS

Peelable Coating Mask - Synthetic

PCS is a synthetic peelable coating mask designed to offer a longer shelf life over standard latex products. It is

suitable for masking components, connectors and other items during the conformal coating process. It is also

suitable as a spot mask for wave soldering applications.



Ammonia free product; offers longer shelf-life and improved odour when curing



Thermal cure; offers fast application and processing times



Prevents coating ingress into connectors and components due to the capillary effect



Suitable for use with dip, spray or brush applied conformal coatings

Directions for Use

PCS should be applied to the area being masked to a thickness of at least 1mm to enable easy peeling after

use. Dry at 65°C for at least 30 minutes (2 hours at 23°C). This can be accelerated by heating @ 80°C. Thicker

films may require longer drying times. As PCS dries it changes in colour from pink to red and must be fully dry

before the conformal coating or wave soldering process.

Following application of a conformal coating, PCS can be removed by peeling off once the coating is touch dry.

The conformal coating may then be secondary or heat cured if applicable, according to the manufactures

guidelines. When used as a solder mask, PCS can be removed by peeling off after the process, once the

substrate has cooled to room temperature.
