LOCTITE STYCAST PC 18M

Loctite Stycast PC 18M is a single-component, solvent-based polyurethane conformal coating engineered to protect printed circuit boards (PCBs) and electronic components from moisture, corrosion, chemicals, and mechanical abrasion. Designed for demanding environments, this high-performance coating delivers long-lasting reliability in a wide range of industries including aerospace, automotive, defence, consumer electronics, and industrial manufacturing.

Once cured, Loctite PC 18M forms a clear, flexible film that provides a tough yet elastic barrier against humidity, salt spray, and chemical vapours. Its excellent dielectric strength and environmental resistance help maintain signal integrity and functionality even under extreme operating conditions. The coating remains stable over a broad temperature range, making it well-suited for electronics that face thermal cycling or mechanical stress.

The formulation supports both manual and automated application methods such as brushing, spraying, or selective coating systems. It is UV-traceable, allowing for easy inspection under blacklight to ensure complete coverage and quality control during production.

Loctite Stycast PC 18M is ideal for conformal coating applications where:

• Flexibility and vibration resistance are important

• Long-term environmental protection is critical

• Transparent coating is preferred for visual inspection

• Low VOC requirements are not strictly enforced

Key Benefits:
