Covestro Desmodur® N75 BA light-resistant HDI biuret curing agent with good chemical resistance and flexibility

Solubility/Dilution
Desmodur® N75 BA can be used with esters, ketones, and aromatic hydrocarbon solvents such as: propyl methoxyacetate, acetone, methyl ethyl ketone , methyl isobutyl ketone, cyclohexanone, toluene, xylene, No. 100 naphtha solvent and their mixtures for dilution. Generally have good miscibility with these solvents. However, the resulting solution must be tested for storage stability. Polyurethane grade solvents should be used (water content less than 0.05%, no reactive groups such as hydroxyl or amino groups). Butyl acetate and ethyl acetate are not recommended as the sole and primary diluents because solutions with low solid content are unstable. Aliphatic hydrocarbons are not suitable as solvents. Desmodur® N75 BA should not be diluted below 40% solids. Solutions with low base content may develop turbidity and sedimentation after long-term storage.

Compatibility
Desmodur® N75 BA can generally be used with the following products. Namely: Desmodur® N3200, N3300, N3400, N3600 and Desmodur® Z4470 aliphatic polyisocyanates;

Desmodur® L, HL and IL type aromatic polyisocyanates; Desmophen® 651 and 670 type polyester polyols; Desmophen® A type polyacrylate; Desmophen® 1380BT type polyether Polyol. However, the compatibility of the prepared solution must be tested.

Features/Applications
Desmodur® N75 BA is mainly used as the curing agent component of light-resistant two-component polyurethane coatings with good chemical resistance. properties, weather resistance, excellent gloss retention and excellent mechanical properties. The ideal coreactants are polyacrylates or polyester polyols. Coating systems formulated with Desmodur® N75 are suitable for self-drying and oven drying and are used in automotive and industrial coatings such as wood, furniture, plastic finishing and corrosion protection.
