Product Specification
1322 Solvent-Based Polyurethane Conformal Coating Material
1322 Conformal Coating is a single-component, solvent-based polyurethane coating material designed to provide reliable insulation and protection for assembled printed circuit boards (PCBs). This environmentally friendly coating is formulated without aromatic solvents (such as benzene, xylene, and C9 aromatic compounds) and contains no free isocyanates or isocyanate radicals, making it a safer choice for operators and the environment.
Ideal for flexible circuit boards and demanding electronic applications, 1322 offers excellent aging resistance, moisture protection, and anti-condensation properties that effectively prevent electrochemical corrosion and electronic migration.
