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 application
DINITROL 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 promoters
Plastic primer
Zinc or aluminium primer
Wood primer
Glass primer
Method of use
DINITROL 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 coating
2-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.
