In art, in particular drawings in pastels, charcoal, chalk, and other dry media, a fixative is a kind of preserving agent applied over the top of the drawing to prevent crumbling, [1] smudging, fading, and discolouring.
Xylene is a solvent that is often used in paints including spray paint and therefore found in many spray-painting environments. Xylene is a colorless and flammable liquid that is also a hazard to the wellbeing of many humans. [21] Xylene is harmful when exposed to human skin or, in more extreme cases, eyes, nose, and throat.
Hindered amine light stabilizers (HALS) are chemical compounds containing an amine functional group that are used as stabilizers in plastics and polymers. [1] These compounds are typically derivatives of tetramethylpiperidine and are primarily used to protect the polymers from the effects of photo-oxidation; as opposed to other forms of polymer degradation such as ozonolysis.
Spray paint (formally aerosol paint) is paint that comes in a sealed, pressurized container and is released in an aerosol spray when a valve button is depressed. The propellant is what the container of pressurized gas is called. When the pressure holding the gas is released through the valve, the aerosol paint releases as a fine spray. [1]
Austenite, also known as gamma-phase iron (γ-Fe), is a metallic, non-magnetic allotrope of iron or a solid solution of iron with an alloying element. [1] In plain-carbon steel , austenite exists above the critical eutectoid temperature of 1000 K (727 °C); other alloys of steel have different eutectoid temperatures.
In industrial chemistry, a stabilizer or stabiliser is a chemical that is used to prevent degradation. [1] Above all, heat and light stabilizers are added to plastic and rubber materials because they ensure safe processing and protect products against aging and weathering.
Light stabilizer are used to inhibit polymer photo-oxidation, which is the combined result of the action of light and oxygen. Like autoxidation this is a free radical process, hence the antioxidants described above are effective inhibiting agents, however additional classes of additives are also beneficial, such as UV absorbers, quenchers of ...
Anti-scratch coatings are generally applied via spray (hand or automated), dip, spin, roll or flow coating. Coating Formation uses "Precision factor" to affect topology-dependent Scratch properties. "Precision factors" include additive concentration , coating thickness , and Viscosity .
