Product Specifications

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

Solubility/ Dilution
Desmodur® N3300 can use esters, ketones, 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, it has good miscibility with the above solvents. However, the storage stability of the prepared solution must be tested. Polyurethane grade solvents should be used (less than 0.05 % water, 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 binder content may develop turbidity and precipitation 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 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® 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 lightfast 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 force-drying coating systems based on Desmodur® N3300 are automotive original equipment (OEM), car refinishing, transport, industrial goods and plastics of finishing.

Save
Desmodur® N3300 is moisture sensitive and should therefore be stored in airtight in original container. When stored under proper conditions at room temperature, this product has a shelf life of at least 6 months.

Safety: Hazard Identification
May cause an allergic reaction by skin contact. The inclusion of isocyanates must strictly adhere to the safety data sheet. It includes relevant information such as labeling, transportation and storage, as well as relevant information on product use, product safety and ecology.
