DINITROL 410 UV NF is a 1-component polyurethane sealing and bonding compound with good resistance and UV stability. The sealer is quick-drying and elastic, and can be coated with most lacquers.Areas of applicationDINITROL 410 UV NF is used for bonding and sealing in a range of industrial areas, such as bus, trucks and caravan construction and shipbuilding. The material adheres well to primed and lacquered metals, duroplastics (glass fibre reinforced plastics, hard PVC), wood and glass. It is suitable for sealing overlapping and expansion joints in visible interior and exterior areas in commercial vehicle construction. We recommend carrying out an adhesion test before applying to complex substrates.Special primers/Adhesion promotersPlastic primerZinc or aluminium primerWood primerGlass primerMethod of useDINITROL 410 UV NF is used at room temperature. The surface to be treated must be clean and free from dust, oil and grease. To clean contaminated substrates please use DINITROL 582. For cartridges and tubular bags, standard supply guns can be used. Dimension and thickness of the adhesive beat depend on the max. stress due to the move inside the bonded joint. The curing of the DINITROL 410 UV NF depends on the dimension of the joint, air humidity and temperature.Lacquer coating2-C acrylic paints, elastic paints (latex paints, watersoluble acrylic paints). Water-soluble paints should be tested for suitability beforehand. Alcohol-based paints or alkyd resin paints impair hardening and may only be used on completely hardened sealing compound. In order to prevent the formation of blisters at higher temperatures, make sure the sealer is completely hardened. Expansion joints must only be coated with elastic paints. Concerning nitro cellulose paints, a suitability test must be carried out prior to application.Technical DataBlack, RAL on requestRaw material base Polyurethane, pre-polymer, dries by air humidityConsistency pasteFlow (2.6 mm/ 2.8 bar 20°C) 40 – 60 g/min cartridgeDensity (20°C) ~ 1.2 g/mlProcessing temperature + 5 °C to + 35 °CTemperature resistance – 40 °C to + 90 °C (short-term to 120 °C)Resistance (cured) long-term: water, salt water, diluted acids andalkalis, aqueous cleanershort-term: petrol, grease and mineral oilCleaning Non-hardened material: Petroleum spiritHardened material: Can only be removedmechanically.Skin formation time ~ 30 min at 23 °C / 50 % RTSurface drying ~ 2.5 h (tack free)Hardening speed ~ 3 mm per 24 h at 23 °C / 50 % r.h.Shore A hardness (DIN 53505) > 45Tensile strength (DIN 53504) 1,4 N / mm²Tear propagation resistance (DIN 53504) ~ 8 N mmElongation at break (DIN 53504) 400 %Modulus of elasticity (DIN 53504) 100% ~ 1.0 N/mm² after 24 hStorage time Between 15°C and 25°C 12 monthsNote: Seal opened packages immediately after use
