## Description

HumiSeal 1A33 Aerosol is a fast drying, clear urethane conformal coating intended for use on printed circuit assemblies.

The coating may be removed chemically using HumiSeal Stripper 1063.

Review: Casual observer’s reaction to random 1-star rating - This is a highly respected product used in the aerospace industry to mitigate corrosion and tin whisker shorts on electronic components. As with any specialized product, the instructions for use, including consideration of environmental variables such as curing temperatures, must be adhered to in order to obtain optimal performance.
Review: Very Slow Cure - 30 day cure at room temperature. I couldn’t heat, was using in cold environment, and couldn’t use partially cured.
