\nDesmodur\u00ae N3400 is mainly used as a reactive diluent or curing agent for weather-resistant two-component polyurethane coatings, and as a resin for one-component moisture-curing polyurethane coatings. Desmodur\u00ae N3400 is usually mixed with other aliphatic polyisocyanates in two-component systems, such as Desmodur\u00ae N3200, ultra N3300, N3600 and Z4470. An ideal co-reactant is a hydroxyl polyacrylate. In one-component polyurethane systems, Desmodur\u00ae N3400 can be used as a single resin or mixed with other polyisocyanates, such as Desmodur\u00ae N3200 and ultra N3300. Due to its low viscosity, Desmodur\u00ae N3400 can also be used as a hardener in waterborne two-component polyurethane coatings.<\/h4>\n<\/h4>\nCompatibility<\/strong>
\nGenerally, Desmodur\u00ae N3400 can be mixed with the following products: aliphatic polyisocyanate such as Desmodur\u00ae N100, N75, N3200, ultra N3300, N3600 and Z4470; aromatic polyisocyanate such as Desmodur\u00ae L\/ ultra L, HL and IL\/ ultra IL; hydroxyl polyester such as Desmophen\u00ae 670; hydroxyl acrylate such as Desmophen\u00ae A series products. However, it is advisable to perform a compatibility test before each mixed use. Desmodur\u00ae N3400 is not very compatible with branched hydroxylated polyesters such as Desmophen\u00ae 651.<\/h4>\n<\/h4>\nSolubility\/Dilution<\/strong>
\nDesmodur\u00ae N3400 can be diluted by solvents such as esters, ketones and aromatic hydrocarbons, such as ethyl acetate, butyl acetate, propylene glycol methyl ether acetate, acetone, methyl ethyl ketone, methyl Isobutyl ketone, cyclohexanone, toluene, xylene, No. 100 mineral spirits and their mixtures. Generally, it has good compatibility with the various solvents listed, but the storage stability of its diluted solution still needs to be tested. Polyurethane grade solvents should be used (less than 0.05% water and should not contain reactive groups such as hydroxyl or amino groups in the solvent). Aliphatic hydrocarbons are not suitable as solvents.
\nDesmodur\u00ae N3400 cannot be diluted below 40% solids. Long-term storage of solutions with low resin content may cause turbidity and precipitation.<\/h4>\n<\/h4>\nSave<\/strong>
