1A33 Urethane Conformal Coating

HumiSeal 1A33 is a premium, single-component polyurethane conformal coating designed to provide superior protection and insulation for printed circuit boards and sensitive electronic assemblies. This high-solids, low-viscosity formula offers exceptional chemical and moisture resistance, creating a rugged barrier against harsh environmental contaminants while maintaining excellent dielectric properties. Engineered for versatility, 1A33 is qualified to MIL-I-46058C and IPC-CC-830 standards and features a built-in UV tracer to facilitate easy visual inspection under blacklight. Whether applied via spray, dip, or brush, it cures at room temperature to a flexible, durable finish that withstands mechanical stress and thermal shock, making it the industry standard for aerospace, automotive, and industrial electronics applications where long-term reliability is non-negotiable.

• Premium Protection & Reliability: This single-component polyurethane coating provides a rugged, flexible barrier that shields printed circuit boards (PCBs) from moisture, salt spray, and chemical contaminants.
• Military-Grade Certification: Engineered for high-stakes environments, HumiSeal 1A33 is fully qualified to MIL-I-46058C and IPC-CC-830 standards, ensuring it meets the rigorous demands of aerospace and defense applications.
• Integrated UV Tracer: Formulated with a built-in fluorescent tracer that glows under blacklight, allowing for rapid and accurate visual inspection of coating coverage and quality control.
• Superior Dielectric Properties: Delivers high insulation resistance and dielectric strength to prevent electrical arcing and short circuits in densely packed electronic assemblies.
• Versatile & Easy Application: Features a low-viscosity formula that can be applied via spraying, dipping, or brushing, curing at room temperature to a durable finish that resists thermal shock and mechanical stress.
