Easy-to-Handle Moisture Scavenger
Additive OF is a stabilizer additive / moisture scavenger for solvent-based polyurethane coatings. This solution is 100% active.
Benefits of Easy-to-Handle Moisture Scavengers
Additive OF provides long-term dehydration in coatings. Benefits include improved storage stability and the reduced likelihood of moisture-related issues being present. Moisture-related issues include gloss reduction, haze formation, and foam generation. This product’s reaction produces fast evaporating solvents which are non-toxic and do not cause gassing.
Additive OF is ideal for solvent-based 1k and 2k polyurethane coatings. It can be used as a package stabilizer. Additive OF can be added directly to the polyol or isocyanate component.
Appearance Clear colorless
Density 0.89 g/cm3 Color APHA: Max. 20,
- Low viscosity
- Eliminates moisture in solvent-based 1K and 2K
- Compatible with most polyol and isocyanate components
- The combination of Additive TI and Additive OF in the
formula stabilizes the polyurethane coating (direct contact
between Additive TI and Additive OF should be avoided as
this could render them ineffective)
- In pigmented one-component polyurethane formulations
Additive TI should be added to the dispersion phase to
remove any water present and then Additive OF should be
added in the letdown
- Solvent-based polyurethane coatings
The recommended range of Additive OF is 1 – 3 % as supplied based on the total weight of the coating. Exact amounts should be experimentally determined and will be dependent on the individual system.
Protect from the effects of weathering and store at temperatures between 5 and 30 °C. Once opened, containers should be resealed immediately after each removal of the product.
