Anti-scratch coating is a type of protective coating or film applied to an object's surface for mitigation against scratches. Scratches are small surface-level cuts left on a surface following interaction with a sharper object. Anti-scratch coatings provide scratch resistances by containing tiny microscopic materials with scratch-resistant ...
A 'non-stick surface' is engineered to reduce the ability of other materials to stick to it. Non-sticking cookware is a common application, where the non-stick coating allows food to brown without sticking to the pan.
Food contact material pictogram (left) on a plastic food container in Hong Kong. Food contact materials or food contacting substances (FCS) [1] [2] are materials that are intended to be in contact with food. These can be things that are quite obvious like a glass or a can for soft drinks as well as machinery in a food factory or a coffee machine.
A coating is a covering that is applied to the surface of an object, or substrate. [1] The purpose of applying the coating may be decorative, functional, or both. [2] Coatings may be applied as liquids, gases or solids e.g. powder coatings.
A boundary can be drawn by whether a reaction or crosslinking of the coating takes place (automotive clear coat) or whether a plastic merely melts and solidifies on the surface (vortex sintering with thermoplastics), but the transitions are fluid. As a rule, plastic coatings have significantly higher film thicknesses than conventional paint.
Release agents are coated onto some plastic films to prevent adhesives from bonding to the plastic surface. Some release agents, also known as de-molding agent, form oil, parting agent or form releaser, are substances used in molding and casting that aid in the separation of a mould from the material being moulded and reduce imperfections in ...
Where r is the Wenzel roughness ratio, n is the number of distinct surface features in the design of the surface, and φ is the area fraction of the tops of the distinct surface features. A completely smooth surface would have an ERI = 0. Using this equation, the amount of microfouling spores per mm 2 can be modeled. Similar to actual shark ...
Even for objects made from the same type of plastic, different applications may have different stabilisation requirements. Regulatory considerations, such as food contact approval are also present. Environmentally friendly stabilizers for bioplastics should be made from bio-based materials, e.g. epoxidized soybean oil , and cause hardly any ...
