Polyurethane Paint and coatings

Polyurethane is a very common polymer. It’s used for wire insulation and cable jackets, building insulation, coated fabrics, furniture cushions, car parts, sportswear and equipment, shoe soles, tires, machine parts, coatings, sealants and adhesives. Most polyurethanes are thermosetting polymers (thermosets) so they don’t melt when heated although there are some thermoplastic polyurethanes. Thermoplastics melt when hot enough. There are hundreds if not thousands of polyurethane coatings and paints used in scores of industries. When cured, all result in a tough, waterproof film that can be highly resistant to wear and the elements.


Acrylic Urethane Automotive and Aircraft Paint

Vehicle and aircraft manufacturers and automotive body shops apply acrylic urethane topcoats. Attesting to the versatility of urethanes is the fact that the same products are commonly used to restore bathtubs.

Water Towers that win awards leave “A Lasting Impression”

Tnemec.com news on the water towers coated with various products that received awards. Information on the individual projects includes specifics on the materials and surface preparation. The exterior of the tank pictured here was prepared in accordance with SSPC-SP7/NACE No. 4 Brush-Off Blast Cleaning and was primed with one coat a modified polyamine epoxy (Tnemec’s Series 135 Chembuild for marginally prepared steel and tightly adhering old coatings). Tnemec’s Series 1075 Endura-Shield II, an aliphatic acrylic polyurethane was the intermediate coat. This product is highly resistant to abrasion, wet conditions and exterior weathering. The finish coat was an advanced fluoropolymer, Tnemec Series 700 HydroFlon. Two coats of Series 700 were also used for the lettering and mural. Nineteen colors used in the mural, ranging from tank white, to different shades of blues, greens and browns. Multiple projects are described on this page and although some use the same materials there are many variations. Reviewing the information that Tnemec has provided will help anyone seeking to coat similar steel structures or specify the requirements for doing so.
