Covestro Desmodur N3390 BA/SN HDI trimer curing agent standard light-resistant curing agent

Product Specifications

*The above values ​​are general information and do not belong to the product specifications.

Solubility/Dilution
Curing agent N3390 can be used with esters, ketones, and aromatic hydrocarbon solvents such as: ethyl acetate, butyl acetate, methoxypropyl acetate, acetone, methyl ethyl ketone, methyl isobutyl Dilute with ketone, cyclohexanone, toluene, xylene, 100# solvent naphtha and their mixtures. The miscibility with the above solvents is generally very good. However, 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.
Curing agent N3390 should not be diluted to less than 40% solid content. Solutions with low base material content will appear turbid and precipitated during long-term storage.

Compatibility
Curing agent N3390 is generally miscible with the following products. Namely: curing agents N100, N75, N3200, N3400, N3600 and curing agent Z4470 aliphatic isocyanates; curing agents L, HL and IL aromatic polyisocyanates; Desmophen 670 polyester polyols; Desmophen A polyacrylate. However, the compatibility of the prepared solution must be tested. Hardener N 3390 is not compatible with branched polyester polyols such as Desmophen 651 or polyether polyols such as Desmophen 550U.

Features/Applications
Curing agent N3390 is mainly used as the curing agent component of light-resistant two-component polyurethane coatings. The coating has excellent chemical resistance and weather resistance, outstanding gloss retention and Excellent mechanical properties. The ideal coreactants are polyacrylates or polyester polyols.
The coating system formulated with curing agent N3390 is suitable for self-drying or baking, and is used for the coating of automobile original paint (OEM), automobile repair, transportation vehicles, industrial products and plastics.

Save
Curing agent N3390 is sensitive to moisture, so it should be stored in the original sealed container. If stored under proper conditions, this product has a shelf life of at least 6 months.

Security
Flammable, skin contact may cause allergic reactions. Harmful to aquatic life and may cause long-term adverse effects in the aquatic environment. Contains isocyanates.
