2. List of polyurethane applications - Wikipedia

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

   Exterior use of polyurethane varnish may be problematic due to its susceptibility to deterioration through ultra-violet (UV) light exposure. All clear or translucent varnishes, and indeed all film - polymer coatings (i.e., paint , stain , epoxy , synthetic plastic , etc.) are susceptible to this damage in varying degrees.

3. Exterior insulation finishing system - Wikipedia

   Adhesives and finishes that are cementless harden by the evaporation of water. Adhesives come in two forms: The most common is in a plastic pail as a paste, to which Portland cement is added and as dry powders in sacks, to which water is added. Finishes come in a plastic pail, ready to use, like paint. EIFS insulation comes in individual pieces ...

4. Polymer concrete - Wikipedia

   en.wikipedia.org/wiki/Polymer_concrete

   Polymer concrete is a type of concrete that uses a polymer to replace lime-type cements as a binder. One specific type is epoxy granite , where the polymer used is exclusively epoxy . In some cases the polymer is used in addition to portland cement to form Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC). [ 1 ]

6. Thermoplastic polyurethane - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic_polyurethane

   Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.

7. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   A building site for a row of riverside apartment blocks in Cambridge. The buildings are being constructed using a systems build with a steel frame and various prefabricated components. The blue plastic on the central building is the vapour barrier for the thermal wall insulation before the exterior cladding has been fixed.
