- 2.78 Relative Evaporation Rate
- 24-Month Shelf Life
Product Description
HumiSeal® Thinner 802 is a proprietary solvent and diluent blend formulated for use with HumiSeal® UV40 conformal coating. It is used to lower the coating’s as-supplied viscosity or restore its original viscosity during processing while maintaining the balance of the compatible coating system. The clear liquid has a relative evaporation rate of 2.78, based on butyl acetate equal to 1, and a specific gravity of 0.86.
Key features
- UV40 compatibility: Specifically identified for use with HumiSeal® UV40 conformal coating.
- Viscosity adjustment: Supports lowering the coating’s as-supplied viscosity or restoring viscosity during processing.
- Balanced solvent blend: Formulated to maintain the original system balance when added to the compatible coating.
- Clear liquid: Supplied with a specific gravity of 0.86 and a relative evaporation rate of 2.78.
Applications / Suitable for
- Adjusting the viscosity of HumiSeal® UV40 conformal coating
- Restoring the original coating viscosity during processing
