Specifications

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

Solubility/Dilution
Desmodur ® 3790BA can be used with esters, ketones, and aromatic solvents such as: ethyl acetate, butyl acetate, methoxypropyl acetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene, xylene, 100 No. naphtha solvent and its mixture diluted. Generally have good miscibility with these solvents.
But The storage stability of the prepared solution must be tested. Polyurethane grade solvents should be used (less than 0.05% water, 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 binder content may develop turbidity and precipitation 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 type aliphatic polyisocyanate; Desmodur® L, HL and IL type aromatic polyisocyanate; Desmophen® 670 type polyester polyol; Desmophen® A type polyisocyanate Acrylate. However, the compatibility of the prepared solutions must be tested. Desmodur® N3790 is not compatible 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 lightfast two-component polyurethane coatings, which have excellent chemical and weather resistance, outstanding gloss retention and excellent mechanical properties. Ideal co-reactants are polyacrylate or polyester polyols. Coating systems formulated with Desmodur® N3790 are suitable for self-drying or baking and are used for the finishing of automotive original equipment (OEM), car refinishing, transportation vehicles, industrial products and plastics.

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