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. 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 ...

5. Conformal coating - Wikipedia

   en.wikipedia.org/wiki/Conformal_coating

   There are limitations in the select coat process, such as capillary effects around low-profile connectors that absorb the coating accidentally. The process quality of dip or dam-and-fill coating and non-atomized spray technology can be improved by applying and then releasing a vacuum while the assembly is submerged in the liquid resin.

6. UV coating - Wikipedia

   en.wikipedia.org/wiki/UV_coating

   UV coatings have been applied to mechanical tubing, safety/water suppression pipe and OCTG/line pipe for many years. UV coatings advantages in this application can be summarized as faster, smaller, and cleaner with no thermal ovens required. The coating and curing (almost instantly) at speeds ranging from 100 feet per minute to over 800 feet ...

7. Conservation and restoration of lacquerware - Wikipedia

   en.wikipedia.org/wiki/Conservation_and...

   Wet cleaning is the process of further removal of dirt, grime and residue from the surface of the object that is not successfully removed by dry cleaning. Testing of various solvents should be done prior to wet cleaning the surface of the object in order to prevent possible damage to or removal of the original lacquer surface. [ 16 ]
