HumiSeal Thinner 903
Harmonization Code : 3814001000 |

Main features
- Slower evaporation rate
- Smoother flow
- Better leveling
Product Description
Consider using HumiSeal Thinner 903 to adjust conformal coating viscosity when improved flow and leveling are required. Thinner 903 has moderate evaporation rate (~1) and higher boiling point, meaning the solvent stays wet longer, which helps coatings self-level for a smoother finish.
Product Key Features
- Slower‑evaporating
- Ideal for smoother flow and better leveling on these conformal coatings
