2. Retrobright - Wikipedia

   en.wikipedia.org/wiki/Retrobright

   Retrobright (stylized as retr0bright or Retrobrite [1]) is a hydrogen peroxide-based process for removing yellowing from ABS plastics. Yellowing in ABS plastic occurs when it is exposed to UV light or excessive heat, which causes photo-oxidation of polymers that breaks polymer chains and causes the plastic to yellow and become brittle.

3. 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.

4. J-B Weld - Wikipedia

   en.wikipedia.org/wiki/J-B_Weld

   While J-B Weld Original epoxy dries to a dark grey color, [10] J-B Weld's ClearWeld epoxy dries clear. [11] Although its bond is not quite as strong as the Original's (3900 psi vs. 5020 psi), [ 12 ] ClearWeld is often preferred when appearance is an important consideration.

5. 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 ...

6. Photo-oxidation of polymers - Wikipedia

   en.wikipedia.org/wiki/Photo-oxidation_of_polymers

   Here, the UV radiation and rough weathers belabor the polymer so much, that the material has to be replaced frequently. Poly(ethylene-naphthalate) (PEN) can be protected by applying a zinc oxide coating, which acts as protective film reducing the diffusion of oxygen. [51]

8. 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 ...
