Technical content
PCM is a flexible, solvent resistant latex for masking componen ts, connectors and other items during the conformal coating process. It is also suitable as a spot mask f or wave soldering applications. The high film strength of PCM means that it can be peeled by hand without breaking or leaving residues.
- Flexible latex with high film s trength; leaves no residue even when removed from complex areas
- Allows selective coating of cir cuit boards; masks components and connectors during coating application
- Prevents coating ingress into connectors and components due to the capillary effect
- Suitable for use with dip, spray or brush applied conformal co atings Approvals RoHS-2 Compliant (2011/65/EU): Yes Liquid Properties D e n s i t y @ 2 0 ° C ( g / m l ) : 1 . 2 0 S o l i d s C o n t e n t : 7 0 - 7 4 % Viscosity Brookfield LVT (mPa s): 30,000 to 60,000 A m m o n i a C o n t e n t : 0 . 2 9 % M a x p H : 1 0 - 1 1 Drying Time (2mm thickness): 2 hours @ 25°C o r , 3 0 m i n s @ 6 0 ° C Cured Properties Tensile Strength: 16.57 MN/m E l ongation at Break: 900% Modulus @ 300%: 0 . 8 8 M N / m Modulus @ 700%: 6 . 1 8 M N / m Description Packaging Order Code Shelf Life Peelable Coating Mask 250ml Bottle PCM250ML 12 Months
Masking should take place between the cleaning and coating process. PCM should be applied to the area being masked to a thickness of at least 1mm to enable easy peeling af ter coating. Dry at room temperature for at least 2 hours. This can be accelerated by heating to 60°C 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 confo rmal 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 prot ected area or component clean and free from coating. The conformal coating may then be heat cured if applicable. Note: This product contains Amm onia. It should be applied and allowed to dry in a well-ventilated area. Store below 30°C. Please refer to MSDS for further information. Revision 2: Oct 2016
