Product Introduction
Electrolube PCM is a peelable coating mask specifically designed
for electronics manufacturing. It features a flexible latex
formulation with high film strength and solvent resistance,
ensuring easy masking of components and connectors during the
conformal coating process. Its primary function is to prevent
coating ingress via capillary action and allow residue-free removal
by hand. The product is suitable for brush, spray, or dip coating
applications, enabling selective coverage and efficient protection.
Enhanced Properties
Building on the parameters from Part 1, PCM's special attributes
include its high tensile strength (16.57 MN/m) and exceptional
elongation at break (900%), allowing flexibility without breakage
on complex geometries. The high solids content (70-74%) enables
rapid drying for thick films (e.g., 2 hours@25°C for 2mm
thickness), while high viscosity (30,000-60,000 mPa s) ensures
uniform coverage. Additionally, low ammonia content (max 0.29%) and
alkaline pH (10-11) support environmental friendliness but require
ventilation during use. These attributes collectively enable
residue-free removal and ingress prevention, making it ideal for
precision electronics protection.
Application Scenarios
Electrolube PCM is specifically used in electronics manufacturing
for conformal coating processes as a mask to protect sensitive
components like connectors, IC chips, and solder joints, preventing
coating coverage. Typical applications include selective coating on
printed circuit boards (PCBs), where PCM is applied manually or
automatically to shield areas, ensuring coating only on designated
sections. Based on online information for the same model (source:
Electrolube official website product page), PCM is widely adopted
in automotive electronics, aerospace, and consumer electronics to
enhance reliability and prevent failures from moisture or dust. For
example, in automotive ECU production, PCM protects connector ports
to avoid coating-induced short circuits.
