The invention relates to the field of the protection of security documents such as for example banknotes and identity documents against counterfeit and illegal reproduction. In particular, the present invention provides magnetic assemblies and methods for producing optical effect layers (OELs) on a substrate, said method comprising a step of exposing a coating composition comprising platelet-shaped magnetic or magnetisable pigment particles to the magnetic field of the magnetic assembly so as to bi-axially orient at least a part of the platelet-shaped magnetic or magnetisable pigment particles.

Method for coating a substrate with a coating material is described, in particular with a coating or photoresist, wherein said substrate is provided in said method. Said coating material is applied to said upper side of said substrate. A gas flow is generated, said gas flow being directed from said underside of said substrate to said upper side of said substrate, wherein said gas flow prevents a bead of said coating material forming on said edge of said upper side of said substrate or a previously existing bead is removed by means of said gas flow. In addition, a coating system is described.

The present disclosure provides a method for enhancing resistance to delamination of a coating layer applied to a rigid, monolithic substrate (204, 404). The method comprises forming a plurality of holes (208, 408) on the substrate (204, 404), to define passages from a first operative surface to a second operative surface of the substrate (204, 404). The first operative surface is coated with a first coating material and the second operative surface is coated with a second coating material, to obtain a first operative surface having a first coating layer (202, 402), and a second operative surface having a second coating layer (206, 406). A portion of the first coating material and/or the second coating material is allowed to flow through the passages to configure contiguous ties (210, 410) between the first and the second coating layer. The contiguous ties formed between the first and the second coating layer aid in enhancing the resistance to delamination of the coating layer applied to the rigid, monolithic substrate (204, 404).

A dielectric nanolubricant composition is provided. The dielectric nanolubricant composition includes a nano-engineered lubricant additive dispersed in a base. The nano-engineered lubricant additive may include a plurality of solid lubricant nanostructures having an open-ended architecture and an organic, inorganic, and/or polymeric medium intercalated in the nanostructures and/or encapsulate nanostructures. The base may include a grease or oil such as silicone grease or oil, lithium complex grease, lithium grease, calcium sulfonate grease, silica thickened perfluoropolyether (PFPE) grease or PFPE oil, for example. This dielectric nanolubricant composition provides better corrosion and water resistance, high dielectric strength, longer material life, more inert chemistries, better surface protection and asperity penetration, no curing, no staining, and environmentally friendly, compared to current products in the market.
