Solubility/Dilution
Desmodur® N100 can be used with esters, ketones, and aromatic hydrocarbon solvents Such as: propyl methoxyacetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene, xylene, 100# solvent naphtha and their mixtures for dilution. Generally speaking, it has good compatibility with the above solvents. However, the resulting solution must be tested for storage stability. Polyurethane grade solvents should be used (less than 0.05% water content and no reactive groups such as hydroxyl or amino groups). Aliphatic hydrocarbons are not suitable as solvents. Desmodur® N100 cannot be diluted below 40% solids. Solutions with low base content may develop turbidity and sedimentation after long-term storage.

Compatibility
Desmodur® N100 can generally be used with the following products. Namely: Desmodur® N3200, N3300, N3400, N3600 and Desmodur® Z4470 aliphatic polyisocyanates; Desmodur® L, HL and IL aromatic polyisocyanates; Desmophen® 651 and 670 polyester polyols Desmophen® A polyacrylic acid Ester; Desmophen® 1380BT polyether polyol. However, the compatibility of the prepared solution must be tested. Properties/Applications Desmodur® N100 is mainly used as a curing agent for light-fast two-component polyurethane coatings with high chemical and weather resistance, excellent gloss retention and mechanical properties. Preferred co-reactants are polyacrylates and polyester polyols. Coating systems formulated with Desmodur® N100 are suitable for self-drying or baking and are used in automotive paints and industrial coatings such as wood, furniture, plastics and Anti-corrosion protection. StoreDesmodur® N100 Sensitive to moisture, therefore should be stored in airtight containers. When stored at 5-25°C in the original container, this product has a shelf life of at least 6 months.

Safety: Hazard Identification
Inhalation Harmful, may cause allergic reactions by inhalation and skin contact.
The Safety Data Sheet (028669) must be strictly adhered to. It includes information on labeling, transportation and storage, as well as information on product use, product safety and ecology.

Solubility/Dilution
Desmodur® N100 can be used with esters, ketones and aromatic solvents Such as: methoxypropyl acetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene, xylene, 100# solvent naphtha and their mixtures for dilution. Generally speaking, it has better compatibility 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, free of reactive groups such as hydroxyl or amino groups). Aliphatic hydrocarbons are not suitable as solvents. Do not dilute Desmodur® N100 below 40% solids. Solutions with low binder content may develop turbidity and precipitation after long-term storage.

Compatibility
Desmodur® N100 can generally be used with the following products. Namely: Desmodur® N3200, N3300, N3400, N3600 and Desmodur® Z4470 type aliphatic polyisocyanate; Desmodur® L, HL and IL type aromatic polyisocyanate; Desmophen® 651 and 670 type polyester polyol Desmophen® A type polyacrylic acid Esters; Desmophen® 1380BT-like polyether polyols. However, the compatibility of the prepared solutions must be tested. Properties/Applications Desmodur® N100 is primarily used as a curing agent for lightfast two-component polyurethane coatings with high chemical and weather resistance, excellent gloss retention and mechanical properties. Preferred coreactants are polyacrylates and polyester polyols. Coating systems formulated with Desmodur® N100 are suitable for self-drying or baking, for automotive paints and industrial coatings, such as wood, furniture, plastics and Corrosion protection. StoreDesmodur® N100 Sensitive to moisture and should therefore be stored in tightly closed containers. Stored at 5-25°C in the original container, this product has a shelf life of at least 6 months.
