Applications
MT-N 3800 is used primarily as a hardener component for lightfast, two-component polyurethane coating systems with high chemical resistance and weather stability, very good gloss retention and outstanding mechanical properties. Preferred combination partners are polyacrylate or polyester polyols.The primary field of application for coating systems based on MT-N 3800 are air and heat-drying automotive OEM, automotive refinishing and transportation coatings, as well as industrial coatings and coatings for plastics.
Solubility / thinnability
MT-N 3800is thinnable with esters, ketones and aromatic hydrocarbons such as ethyl acetate, butyl acetate, methoxypropyl acetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene, xylene, and mixtures thereof. Compatibility with the listed solvents is generally good but the storage stability of the respective solutions should be tested. Only PU grade solvents should be used (max. 0.05 % water, free of reactive groups like hydroxyl or amino groups). Aliphatic hydrocarbons are unsuitable as solvents.MT-N 3800 should not be thinned to less than 40 % non-volatile content. With time, lower binder content can lead to turbidity and sedimentation.
Compatibility
MT-N3800 can generally be blended with the following products: aliphatic polyisocyanates such as MT-N 100. N 75. N 3200. N 3400. ultra N 3600 and MT-Z 4470; aromatic polyisocyanates such as MT-NL/ultra L, HL and IL/ultra IL; polyester polyols and polyacrylates. The compatibility of the combinations used in the formulation should always be tested, however. MT-N3800 is incompatible with branched polyester polyols such asSTD-651 and polyether polyols such as MT 1380 BT.
Storage
– Storage in original sealed MT container.
– Recommended storage temperature: 0 – 30 °C.
– Protect from moisture, heat and foreign material.
General information: The product is sensitive to moisture. Storage at higher temperatures will result in increase of color and viscosity. Due to the raw materials used, the product can occasionally exhibit temperature-dependent turbidity. This turbidity can be reversed by thinning with solvents or heating carefully to max. 50 °C without adversely affecting the quality of the product.
