Viscosity,</sp; Dosmodur® N3800 can be mixed with the following products: Aliphatic polyisocyanatesSuch as Desmodur® N100, N75, N3200, N3400, N3600 and Desmodur® Z4470; aromaticPolyisocyanates such as Desmodur® L, HL and IL; polyhydroxy polyesters such as Desmophen® 670;Polyacrylic Esters such as Desmophen® A series. Compatibility must be tested before use. However, Desmodur® N3800 cannot be mixed with branched polyhydroxy polyesters such as Desmophen® 651, polyhydroxy polyethers such as Desmophen® 1380BT, etc. Features/Applications Dosmodur ® N3800 is mainly used as a curing agent in light-resistant two-component polyurethane coating systems. It has high weather resistance and chemical corrosion resistance, excellent gloss retention and outstanding mechanical properties. Preferred co-reactants are polyacrylates or polyhydroxy polyesters. Coating systems based on Dosmodur® N3800 are mainly used in self-drying and forced applicationsDry original car factory paints, automotive refinish and transportation coatings and general industrial and plastic coatings. Save The Product is sensitive to moisture and should therefore be stored in original sealed containers. When room temperatureUnder proper storage conditions, the shelf life of this product is at least 6 months. Safety: Hazard Identification Because Contains isocyanates, which may cause allergic reactions on skin contact. The product safety data sheet must be strictly adhered to, including labeling, transportation, storage and product disposal, Product safety and ecological impact information.
