Technical Data Sheet PCM Peelable Coating Mask Product Decription PCM is a flexible, solvent resistant latex for masking components, connectors and other items during a conformal coating process. PCM ensures that sensitive items and areas requiring further processing are not coated. It is particularly suitable for protecting areas from ingress of conformal coating, e.g. pin connectors, adjustable pots, IC sockets etc. It is also suitable as a spot mask for wave soldering applications. The high film strength of PCM means that it can be peeled by hand without breaking or leaving residues. Features Room temperature or heat accelerated drying. Completely hand-peelable, leaves no residue. Does not dissolve in solvents, does not contaminate conformal coating. High film strength, does not break. Suitable for use with dip, spray or brush applied conformal coatings.

PCM should be applied to the area being masked to a thickness of at least 1mm to enable easy peeling after coating. Dry at room temperature for at least 2 hours. This can be accelerated by heating to 60C for 30 minutes but some discolouration of copper may occur. Thicker films may require longer drying times. As PCM dries it darkens in colour. PCM must be fully dry before being coated. After spray, dip or brush application with conformal coating the coating should be air-dried in accordance with manufacturer s recommendations before PCM is removed. When the coating is dry, peel off PCM by hand to leave the protected area or component clean and free from coating. The conformal coating may then be heat cured if applicable. Note: This product contains Ammonia. It should be applied and allowed to dry in a well-ventilated area. Store below 30C. Please refer to MSDS for further information.
