Overview
Desmodur IL 1351 BA is a polyisocyanate hardener that, when combined with Desmophen polyols, yields very fast-drying polyurethane coating systems. As one of the recommended international brand products in our auxiliary agent range, this hardener is supplied with supply chain resource support for coating formulators who need short drying times and early sandability, particularly for furniture finishing.
Solubility and Thinning Guidance
Desmodur IL 1351 BA generally has good thinnability with esters such as ethyl acetate, butyl acetate, and 1-methoxypropylacetate-2, and with aromatic hydrocarbons such as toluene, xylene, Solvesso 100, and Shellsol A. However, the solutions formed must be tested for their storage stability before use. The product cannot be thinned with white spirit, and alcohols cannot be used, as they react with this hardener. Prolonged storage of a solution with low binder content may result in turbidity and sedimentation. Only PU grade solvents should be used (less than 0.05% water), and the solvent should not contain reactive groups.
Compatibility
This hardener is compatible with a number of Desmophen products, such as Desmophen 1300 and 1100, and with Desmodur products such as Desmodur L/ultra L and N/ultra N.
Properties and Applications
When combined with, for example, Desmophen 1300, this hardener yields very fast-drying systems. These are used in, for example, the furniture industry, where very short drying times and early sandability are required.
Why Fast-Drying PU Systems Matter for Furniture Finishing
In furniture production, coated components typically move through multiple finishing stages, such as sanding, additional coats, and packing, on a tight production schedule. A polyurethane system that dries quickly and reaches early sandability lets a finishing line advance a part to the next stage sooner, reducing work-in-progress inventory and the risk of dust settling on a still-tacky surface. Achieving this balance of fast cure and workable film properties depends on selecting a compatible hardener and polyol combination, correct solvent choice, and controlled application conditions, since an incompatible solvent or excess moisture can affect both dry time and long-term film stability. Formulators should always confirm current mixing ratio, pot life, and recommended solvent blend against the latest technical data sheet for their specific coating system.
