  2. UV curing - Wikipedia

    en.wikipedia.org/wiki/UV_curing

    UV curing is adaptable to printing, coating, decorating, stereolithography, and in the assembly of a variety of products and materials. UV curing is a low-temperature, high speed, and solventless process as curing occurs via polymerization. [2] Originally introduced in the 1960s, this technology has streamlined and increased automation in many ...

  3. Dental curing light - Wikipedia

    en.wikipedia.org/wiki/Dental_curing_light

    The next type of curing light developed was the quartz-halogen bulb; [4] this device had longer wavelengths of the visible light spectrum and allowed for greater penetration of the curing light and light energy for resin composites. [3] The halogen curing light replaced the UV curing light. The 1990s presented great improvements in light curing ...

  4. Photopolymer - Wikipedia

    en.wikipedia.org/wiki/Photopolymer

    Light-activated resins have found a place in floor refinishing applications, offering an instant return to service not available with any other chemical due to the need to cure at ambient temperatures. Because of application constraints, these coatings are exclusively UV cured with portable equipment containing high intensity discharge lamps.

  5. Solid ground curing - Wikipedia

    en.wikipedia.org/wiki/Solid_Ground_Curing

    Solid ground curing (SGC) is a photo-polymer-based additive manufacturing (or 3D printing) [1] technology used for producing models, prototypes, patterns, and production parts, in which the production of the layer geometry is carried out by means of a high-powered UV lamp through a mask.

  6. Curing (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Curing_(chemistry)

    An intermediate case involves a mixture of resin and additives that requires external stimulus (light, heat, radiation) to induce curing. The curing methodology depends on the resin and the application. Particular attention is paid to the shrinkage induced by the curing. Usually small values of shrinkage (2–3%) are desirable. [2]

  7. Photoinitiator - Wikipedia

    en.wikipedia.org/wiki/Photoinitiator

    In chemistry, a photoinitiator is a molecule that creates reactive species (free radicals, cations or anions) when exposed to radiation (UV or visible). Synthetic photoinitiators are key components in photopolymers (for example, photo-curable coatings, adhesives and dental restoratives).

  8. UV coating - Wikipedia

    en.wikipedia.org/wiki/UV_coating

    Other companies such as Arboritec/UVElite and UVGreenCure have continued in the development of new technologies around coating formulation and floor curing machines. Site Applied UV Coatings are available in both 100% solid and water-based formulations.

  9. Dental composite - Wikipedia

    en.wikipedia.org/wiki/Dental_composite

    The first light-curing units used ultra-violet light to set the material, however this method had a limited curing depth and was a high risk to patients and clinicians. [4] Therefore, UV light-curing units were later replaced by visible light-curing systems employing camphorquinone as the photoinitiator. [4] The Traditional Period
