These mouldings are made specifically for StyroTrim® in Belgium by NMC America, Inc, 7000 Central Parkway, Suite 1501, Atlanta, GA 30328. Constituent material: High-density, yellow, rigid polyurethane foam 100% without CFC. Density: Approx. 10.9 pounds/cu ft (175 kg/m3). Factory finish: Matt white acrylic primer to be painted. 2. SPECIFIC PROPERTIES Visible surfaces: The manufacturing technique guarantees a hard and smooth surface, with sharp edges, and the exact reproduction of the motif. Dimensions: Up to 38" (965 mm) in diameter. Thermal and hygrometric dilatation: Tests have shown that the material has a behavior close to that of wood: its dimensions can undergo the influence of variations of temperature and more particularly of humidity. The same precautions of use are applied. Compliance with fitting and storage requirements and good gluing are enough to ensure the quality and the lasting of the product. 3. USE Fitting and storage conditions: For the best result, the product will be fitted and stored in conditions close to those of final use (similar temperature and humidity). Fitting on a wet backing surface (fresh plaster) and in forced drying conditions (heat gun, dehumidifier, exceptionally high temperature) are to be ruled out. Backing: The following backing surfaces are suitable: drywall, indoor plastered surfaces, coated plaster, cement, wood, etc. Surfaces must be clean, dry, free from dust, degreased and flat; rough down if necessary. If the product is to be applied to particular backing surfaces, please consult our technical department. Adhesive and joints: StyroTrim® Adhesive P5. The optimum thickness of the glue is 1/8" (3.175 mm). Apply glue to the whole of the joints and surfaces to be glued. Leave a 1/8" (3.175 mm) joint filled with adhesive at each join. Like any adhesive, the adhesive compound is not used below 46°F (8°C), above 86°F (30°C) or in strong direct sunshine. Surface work: StyroTrim® ceiling centers can take all paints thanks to the coat of primer applied at the factory, except for silicate products 4. SPECIAL INSTRUCTIONS Regulations concerning dangerous substances: StyroTrim® high density polyurethane products are to be classified neither under "very toxic" nor under "toxic", according to the regulations concerning dangerous substances. Environmental protection: All StyroTrim® products are free from solvents, C.F.C. and their manufacturing process respects the environment. Important notes: The elements are strictly decorative to the exclusion of any structural function; they are not designed to withstand loads and should be isolated by flexible joints from elements likely to convey strains or movements.
