2. Polyaspartic esters - Wikipedia

   en.wikipedia.org/wiki/Polyaspartic_esters

   As with aliphatic polyurethane or acrylic coatings, polyaspartic coatings made with aliphatic isocyanates and derivatives are UV and light stable and have a low yellowing tendency. When coating concrete, polyaspartics can be installed in both clear and pigmented form.

3. Polyurea - Wikipedia

   en.wikipedia.org/wiki/Polyurea

   It is thought that polyurea coatings last 25–30 years. [9] Commercial trademarks for Polyurea include Line-X, GLS 100R, and Pentens SPU-1000, to name a few. [10] [11] [12] There are multiple possible polyurea formulations. The Polyurea Development Association is a trade association that represents the interests of polyurea coating ...

4. Roof coating - Wikipedia

   en.wikipedia.org/wiki/Roof_coating

   This means a roof coating actually becomes the top layer of a composite roof membrane and underlying system. As such, the roof coating is the topmost layer of protection for the membrane, receiving the impact of sunlight (both infrared and ultraviolet (UV)), rain, hail and physical damage. Roof Coatings should not be confused with deck coatings.

5. Polyurethane - Wikipedia

   en.wikipedia.org/wiki/Polyurethane

   This is of particular interest in the area of polyurethane coatings, where light stability is a critical factor and is the main reason that aliphatic isocyanates are used in making polyurethane coatings. When PU foam, which is made using aromatic isocyanates, is exposed to visible light, it discolors, turning from off-white to yellow to reddish ...

6. List of polyurethane applications - Wikipedia

   en.wikipedia.org/wiki/List_of_polyurethane...

   Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...

7. Hydrogenated MDI - Wikipedia

   en.wikipedia.org/wiki/Hydrogenated_MDI

   The resins based on this material are useful in coatings for flooring, roofing, maintenance and adhesives, and sealants. They find use in the coatings, adhesives, sealants and elastomers (CASE) applications. [5] [6] A prepolymer made from H 12 MDI and incorporating dimethylol propionic acid can also be converted to light stable polyurethane ...
