Overview
Additive OF is supplied with supply chain resource support for formulators sourcing a low-viscosity moisture scavenger for solvent-based polyurethane coatings. It is designed to eliminate moisture present in solvent-based one-component (1K) and two-component (2K) polyurethane coating systems, and it is compatible with most polyol and isocyanate components used in these formulations.
Key Advantages
This additive contributes low viscosity to a coating formulation while actively removing moisture from solvent-based 1K and 2K polyurethane systems. Because it is compatible with most polyol and isocyanate components, formulators can incorporate this additive into existing polyurethane coating recipes without reworking the base resin system.
Applications of Additive OF in Solvent-Based PU Coatings
This additive is used in solvent-based polyurethane coatings, where moisture control during formulation and storage directly affects coating stability and shelf life. Formulators working with solvent-based 1K and 2K polyurethane systems rely on this additive to help maintain formulation stability by scavenging moisture that would otherwise interfere with the polyol and isocyanate reaction.
Pairing with Additive TI
This additive is designed to be used in combination with Additive TI, and together the two stabilize the polyurethane coating system. Direct contact between Additive TI and Additive OF should be avoided prior to formulation, since this could render both additives ineffective. In pigmented one-component polyurethane formulations, the recommended sequence is to add Additive TI to the dispersion phase first to remove any water present, and then add Additive OF during the letdown stage.
Why Sourcing Consistency Matters for Buyers
Because moisture scavenging performance directly affects how a polyurethane coating batch cures and how the finished film performs in service, buyers should confirm current specifications for this additive against the latest technical data sheet before scheduling a production run. A supplier that consistently delivers this additive to its stated performance characteristics reduces the need to re-qualify a coating formulation with every new batch.
This is particularly relevant for formulators producing pigmented one-component polyurethane coatings at volume, where the correct addition sequence with Additive TI is directly tied to formulation stability and finished coating quality. Buyers should confirm current batch documentation for this additive against the latest technical data sheet before finalizing a production schedule.
What to Consider When Sourcing This Product
Buyers evaluating this additive for the first time should confirm compatibility with their specific polyol and isocyanate components, since coating formulations vary in composition even within the broader solvent-based polyurethane category. Requesting the current certificate of analysis alongside the technical data sheet is a practical way to confirm that a given batch of this additive matches the manufacturer’s published performance characteristics.
Packaging, storage temperature requirements, and shelf life should also be confirmed directly with the supplier, since these factors affect how this additive performs once it reaches a production facility. Buyers sourcing this additive for time-sensitive coating production schedules should discuss lead time and logistics requirements before finalizing an order.
General Handling and Storage Guidance
As with other moisture-sensitive coating additives, Additive OF should be stored in accordance with the supplier’s technical data sheet, typically in a cool, dry, well-ventilated area away from direct sunlight and sources of heat or ignition, since storage conditions can affect the additive’s moisture-scavenging performance over time. Personnel handling this material should follow the handling procedures specified in the safety data sheet.
Buyers should request and review the current safety data sheet for Additive OF prior to receipt, and confirm that on-site storage conditions are compatible with the supplier’s recommended shelf life and temperature range. Proper inventory rotation helps maintain the low-viscosity and moisture-scavenging characteristics described above.
