Covestro Desmodur N3300 HDI trimer curing agent standard light-resistant PU curing agent

Product Specifications

*The above values ​​are general information and are not part of product specifications.

Solubility/ Dilution
Desmodur® N3300 can be used with esters, ketones, and aromatic hydrocarbons Solvents such as: ethyl acetate, butyl acetate, propylene glycol methyl ether acetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene, xylene, 100# solvent naphtha and their mixtures, etc. dilution. Generally has good miscibility with the above 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). Aliphatic hydrocarbons are not suitable as solvents. Desmodur® N3300 should not be diluted below 40% solids. Solutions with low base content may develop turbidity and sedimentation after long-term storage.

Compatibility
Desmodur® N3300 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 polyols Acrylate. However, the compatibility of the prepared solution must be tested. Desmodur® N3300 is not compatible with branched polyester polyols such as Desmophen® 651 or polyether polyols such as Desmophen® 1380 BT.

Features/Applications
Desmodur® N3300 is mainly used as a light-resistant two-component polyurethane coating. Curing agent, the prepared coating has strong chemical and weather resistance, excellent gloss retention and excellent mechanical properties. The best co-reactants are polyacrylates or polyester polyols. The main areas of application for self-drying and forced-drying coating systems based on Desmodur® N3300 are automotive original equipment manufacturers (OEM), automotive refinishing, transportation, industrial products and plastics. of coating.

Save
Desmodur® N3300 is sensitive to moisture and should therefore be stored in a sealed container In original container. When properly stored at room temperature, this product has a shelf life of at least 6 months.

Safety: Hazard Identification
Skin contact may cause allergic reaction. Safety data sheets containing isocyanates must be strictly adhered to. It includes information on labeling, transportation and storage, as well as information on product use, product safety and ecology.
