HumiSeal® 503
HumiSeal® 503, under Product Code HumiSeal® 503, is a versatile conformal coating thinner used to reduce viscosity and optimize application for multiple coating types including 1B12, 1B31, 1B66, and 1B73. This thinner is composed of carefully selected solvents that ensure consistent dilution without altering the core chemistry of the coatings. It allows for a more controlled application—ideal for spraying, brushing, or dipping techniques—while maintaining the coating’s protection capabilities. HumiSeal® 503 is engineered to deliver high-performance results and is fully compliant with the RoHS Directive 2002/95/EC, making it suitable for use in environmentally regulated industries.
