Desmodur® IL 1451

Desmodur® IL 1451 is an aromatic polyisocyanate based on toluene diisocyanate (TDI), primarily used as a hardener component for fast-drying, two-component polyurethane coatings. It is supplied in a solution with approximately 51% content in butyl acetate.

Key specifications of Desmodur® IL 1451 include:

• NCO content: 7.2 - 7.6%
• Non-volatile content: 49.0 - 53.0%
• Viscosity: 175 - 325 mPa·s
• Iodine color value: ≤ 1.0
• Monomeric content: < 0.50%
• Equivalent weight: approx. 570
• Flash point: approx. 26°C
• Density at 20°C: approx. 1.07 g/ml

Desmodur® IL 1451 exhibits good solubility and thinnability with various solvents, including esters and aromatic hydrocarbons, such as ethyl acetate, butyl acetate, toluene, xylene, Solvesso® 100, and Shellsol® A. It is compatible with many polyester-based Desmophen® grades, alkyd resin, and Desmodur® products such as Desmodur® L, HL, and N.

The polyurethane systems formulated with Desmodur® IL 1451 are characterized by their rapid initial drying and early sandability, making them suitable for industrial coating applications, particularly in wood and furniture industries. These systems can be formulated with high solids contents and are applicable with clear or colored coatings.

Desmodur® IL 1451 should be handled with appropriate protective measures due to its reactive nature. It is recommended for use by industrial or trade professionals and not suitable for DIY applications.

Storage recommendations include storing in tightly sealed original containers, protected from moisture, heat, and foreign materials, with a recommended storage temperature of 0º-30ºC. The product has a shelf life of six months from the date of receipt at the customer, provided it is stored correctly.

Users should review health and safety information before handling Desmodur® IL 1451, and any use in specific applications should be tested in advance to determine suitability.
