Specifications

*This data is general information , is not part of the product manual.

Solubility/Dilution
Desmodur ® 3790BA can be used with esters, ketones, and aromatic hydrocarbon solvents such as: ethyl acetate, butyl acetate, methoxypropyl acetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene, xylene, 100 No. naphtha solvents and their mixtures for dilution. Generally have good miscibility with these solvents.
But The resulting solution must be tested for storage stability. Polyurethane grade solvents should be used (less than 0.05% water content, no hydroxyl or amino reactive groups). Aliphatic hydrocarbons are not suitable as solvents. Desmodur® N3790 should not be diluted below 40% solids. Solutions with low base content may develop turbidity and sedimentation after long-term storage.

Compatibility
Desmodur ® N3790 can generally be used with the following products. Namely: Desmodur® N100, N75, N3200, N3400, N3600 and Desmodur® Z4470 aliphatic polyisocyanates; Desmodur® L, HL and IL aromatic polyisocyanates; Desmophen® 670 polyester polyols; Desmophen® A polyisocyanates Acrylate. However, the compatibility of the prepared solution must be tested. Desmodur® N3790 is incompatible with branched polyester polyols such as Desmophen® 651 or polyether polyols such as Desmophen® 1380BT.

Features/Applications
Desmodur ® N3790 is mainly used as the curing agent component of light-resistant two-component polyurethane coatings. This coating has excellent chemical resistance and weather resistance, outstanding gloss retention and excellent mechanical properties. The ideal coreactants are polyacrylates or polyester polyols. Coating systems formulated with Desmodur® N3790 are suitable for self-drying or baking and are used for finishing automotive original equipment (OEM), automotive refinishing, transportation vehicles, industrial products and plastics.

Save
Desmodur ® N3790 is sensitive to moisture and therefore should be stored in the original sealed container. When properly stored at room temperature, this product has a shelf life of at least 6 months.
