Global Proof SP/A Acrylic Protective Lacquer

Protecting sensitive electronics from moisture, dust, and chemical contaminants is a constant challenge in harsh environments. The Global Proof SP/A conformal coating provides a reliable, transparent acrylic barrier that shields PCBs and components from corrosion and electrical failures. Its aerosol spray format ensures even, professional-grade coverage without the need for specialized equipment.

Who is it for

Ideal for electronics manufacturers, repair technicians, and hobbyists who need to safeguard circuit boards in automotive, marine, industrial, or outdoor applications. Whether you are coating a single prototype or a batch of production boards, this coating delivers consistent protection.

Tips

For best results, clean the board thoroughly and apply in a well-ventilated area at room temperature. Shake the can vigorously for one minute before use, and spray from 20–25 cm distance in short, even passes. Allow each coat to dry before applying additional layers. To remove the coating, use isopropyl alcohol while uncured or a dedicated conformal coating stripper after full cure.
