Definitions

  • the present invention is directed to compositions and methods for removing scratches and oxidative damage from plastic covers and lenses.
  • the present invention is directed to restoring clarity and shine to plastic headlight covers, optical lenses, other plastic surfaces, and preventing future damage due to scratching and oxidation.
  • Plastic materials have largely replaced glass as an optically transparent covering for automotive headlights.
  • a typical plastic headlight cover is composed of a molded polycarbonate plastic that is formed into an aerodynamic shape that fits the profile of the front of the automobile.
  • Plastics are superior to glass in a number of respects. Plastics are lighter than glass while having similar clarity, they are more flexible and able to absorb small impacts, and they are much less likely to shatter in response to large impacts. In addition, plastics can readily be molded into a variety of aerodynamic shapes that are more compatible with modern automotive design.
  • Plastics however, present a number of disadvantages. For example, they are prone to scratching and UV-induced oxidative damage. And while plastic headlight covers are typically endowed with coatings that protect against scratching and UV damage, such coatings do not provide 100% protection over time. For example, road particles and other hard, abrasive substances can penetrate the protective coating and cause scratching that degrades the optical properties of the plastic. In addition to physically degrading the optical properties of the cover, scratching leads to a number of other processes that can damage the plastic. For example, scratches (from washing and cleaning the surface) that penetrate the protective coating can allow access to the plastic substrate by exhaust emissions and the chemicals in acid rain.
  • Replacement is one option for car owners with headlight covers that have been badly damaged by scratching and/or oxidation. Replacing the plastic covers is, however, cost prohibitive for many consumers. For example, the typical cost for replacing headlight covers can run anywhere between $200 and $500 per headlight, not including installation costs.
  • Micro-MeshTM One example of a product that has been used to remove scratches from plastics is a system called Micro-MeshTM. Another is Permatex, which used sand paper.
  • the Micro-MeshTM system removes scratches from plastics using a series of rubber- backed sanding cloths with differing sizes of grit. The first step uses a sanding cloth having 2,400 gauge grit. In subsequent steps, sanding cloths of finer grades up to 12,000 gauge grit are used. In addition to using the rubber sanding block, a small amount of antistatic cream is applied after polishing is complete.
  • the Micro-MeshTM system however, has many negative aspects.
  • One negative aspect of using the Micro-MeshTM system is that a large amount of plastic must be sanded away in order to remove even the tiniest of scratches. That is, it is necessary to remove enough of the plastic surface to at least equal the depth of the scratch.
  • a sizable area of plastic must be removed in order to avoid causing optical distortion of the plastic in the surrounding area where the scratch was removed.
  • the user must possess a high level of skill and patience, which requires a high amount of training.
  • repeated scratch removals using this system will greatly reduce the thickness of the plastic and destroy its desired protective properties.
  • Micro-MeshTM sanding system Another negative aspect of the Micro-MeshTM sanding system is the large amount of time it takes to perform each of the series of sandings for each type of grit. Yet another negative aspect of the Micro-MeshTM sanding system is that extensive sanding removes the protective UV coating from the plastic along with the scratches.
  • varnishes such as acrylic spar varnish
  • acrylic spar varnish to essentially fill in and cover scratches in plastic head light cover.
  • These products are easy and quick to use, but they ultimately do not restore the plastic.
  • a coat of varnish merely covers the scratching and oxidation and does nothing to repair the underlying damage to the plastic. Varnishes and paint generally do not adhere to plastic very well and the varnish is likely to flake off in a short period of time.
  • the refractive index of the varnish coating is dissimilar to that of the underling plastic, each of the filled in scratches will act as a micro lens scattering the light from the headlight. While the headlight may look better after applying the coat of varnish, the varnish will not in fact restore the optical properties of the cover.
  • the present invention encompasses novel compositions and methods configured to restore the clarity and light transmission properties of a plastic surface that has been damaged by scratching and ultraviolet induced oxidation.

Abstract

La présente invention porte sur des kits et des procédés de restauration de matière plastique permettant de restaurer de façon efficace les propriétés de transmission de la lumière et de clarté optique d'un protège-lampe en matière plastique sur une automobile ou une autre surface en matière plastique telle qu'un verre de lunettes de soleil ou un verre optique correctif. Les kits et procédés permettant de restaurer des surfaces en matière plastique qui ont été endommagées par rayure et/ou oxydation induite par ultraviolets. Les kits et procédés font intervenir des compositions de polissage et de lustrage dont les particules sont choisies de façon à polir et à lustrer une surface en matière plastique, et une composition protectrice vis-à-vis des ultraviolets qui forme un revêtement dur protecteur vis-à-vis de l'ultraviolet. Les compositions de polissage et/ou de lustrage peuvent comprendre des particules abrasives agglomérées dispersées dans un vecteur sous forme de liquide ou de gel qui diminuent progressivement de taille par rupture lorsqu'elles sont exposées à l'oxygène et à une pression mécanique durant le polissage ou le lustrage.
