Peelable Coating Mask Electrolube PCM For Conformal Coating Component Masking

Electrolube PCM Peelable Coating Mask for Component Masking in Conformal Coating

Product Properties

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.
