Substrate cleanliness is extremely important for the successful application of conformal coatings. Surfaces must be free from moisture, dirt, oils, flux residues, and all other contaminants. Contaminants beneath the coating may lead to issues that can cause assembly failures.
Store in tightly sealed containers, away from excessive heat or cold. HumiSeal®️ products can be stored at temperatures between 0°C and 35°C. Before use, allow the product to reach ambient temperature (18°C to 32°C) for 24 hours.
