Product Overview: MG Chemicals 862 – Peelable Solder Mask

The MG Chemicals 862 Peelable Solder Mask is a high-quality, synthetic latex product designed to provide robust temporary masking of circuit areas and contacts. It is specifically designed to resist solder, rosin, and cleaning fluids, providing reliable shielding for your delicate circuitry during the soldering process. Additionally, it is ideal for gold fingers and printed circuit card edges, ensuring the most vulnerable parts of your circuit board are adequately protected.

One of the standout features of this peelable solder mask is its ease of removal. The mask can be effortlessly peeled off once the wave soldering process is complete and any subsequently applied conformal coating is sufficiently dry. This ensures a clean and precise finish for your projects.

Key Properties of MG Chemicals 862 – Peelable Solder Mask

• Wave Soldering Tolerance: The mask withstands wave soldering, protecting the underlying circuitry from excess heat and solder flow.
• Non-Corrosive: The mask is safe for copper, gold, silver, and solder joints. It does not cause reaction or discoloration, preserving the integrity of your circuits.
• Solvent Resistant: Once cured, the mask is largely insoluble, resisting flux and cleaning solvents.
• Water Soluble: It can be thinned with deionized (D.I.) water to adjust its viscosity according to your specific needs.
• Immersion Resistant: The mask remains insoluble even after curing, ensuring long-lasting protection.
• Various Curing Options: It can be cured at room temperature or through quick heat curing, providing flexibility for your processes.
• Cure Monitoring: To help monitor the curing process, the mask changes from an opaque pink to a translucent red once fully cured.
• Ammonia-Free: The mask does not contain ammonia, preventing copper trace discoloration.

Applications of MG Chemicals 862 – Peelable Solder Mask

Our peelable solder mask is highly versatile and can be used in a range of applications. It can be applied either manually or by using template screening. However, it is advisable not to use silk screening for application. For more automated processes, it is suitable for application using robotic or pneumatic systems.

Whether you are involved in complex industrial soldering jobs or smaller DIY projects, the MG Chemicals 862 Peelable Solder Mask is the ideal solution for shielding your circuit board areas and contacts. Remember, taking the time to adequately protect your circuit board before soldering can save you time and expense in the long run.
