2. List of polyurethane applications - Wikipedia

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

   Polyurethane materials are commonly formulated as paints and varnishes for finishing coats to protect or seal wood. This use results in a hard, abrasion-resistant, and durable coating that is popular for hardwood floors, but considered by some to be difficult or unsuitable for finishing furniture or other detailed pieces. Relative to oil or ...

3. Varnish - Wikipedia

   en.wikipedia.org/wiki/Varnish

   All clear or translucent varnishes, and indeed all film-polymer coatings (e.g. paint, stain, epoxy, synthetic plastic, etc.) are susceptible to this damage in varying degrees. Pigments in paints and stains protect against UV damage. UV-absorbers are added to polyurethane and other varnishes (e.g. spar varnish) to work against UV damage but are ...

4. UV coating - Wikipedia

   en.wikipedia.org/wiki/UV_coating

   UV coating can be applied via most conventional industrial coating applications as well as by silkscreen and 3D printing. [ 8 ] Due to the normally high solids content of UV coating/varnish the surface of the cured film can be extremely reflective and glossy. 80 lb text and heavier weights of paper can be UV coated, however, cover weights are ...

5. Thermoplastic polyurethane - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic_polyurethane

   A TPU resin consists of linear polymeric chains in block-structures. Such chains contain low polarity segments which are rather long (called soft segments), alternating with shorter, high polarity segments (called hard segments). Both types of segments are linked by covalent links so that they actually form block-copolymers.

6. Wood finishing - Wikipedia

   en.wikipedia.org/wiki/Wood_finishing

   Clear finishes are intended to make wood look good and meet the demands to be placed on the finish. Choosing a clear finish for wood involves trade-offs between appearance, protection, durability, safety, requirements for cleaning, and ease of application. The following table compares the characteristics of different clear finishes.

7. Resin-bound paving - Wikipedia

   en.wikipedia.org/wiki/Resin-bound_paving

   The usage of higher-quality UV polyurethane resins ensures greater flexural performance for external applications and the resin will not yellow (non UV aromatic) in appearance when exposed to UV light, the presence also provides greater protection from UV degradation. Non light-stable polyurethanes, although marketed as strong in performance ...
