The invention relates to a coating composition comprising: a) at least one alkyd binder with an oil content of at least 45 wt % and at most 85 wt %, a modified alkyd binder, or a combination thereof; b) at least one amine or imine component selected from the group comprising: polyaspartic acids and esters thereof, (meth)acrylate/aspartate amines, aldimines, ketimines, and combinations thereof; and c) at least one isocyanate compound.

A coating system comprising an epoxy coating layer prepared from an epoxy formulation which comprises an epoxy resin; a curing agent with no more than 4.5 wt % free amine based on a weight solids of the curing agent; and an adjacent layer prepared from a non-isocyanate polyurethane formulation wherein the epoxy formulation and/or non-isocyanate polyurethane formulation optionally further comprise one or more additives selected from the group consisting of solvent, reactive diluent, plasticizer, pigment, filler; rheology modifiers, dispersants, surfactants, UV stabilizers, and corrosion inhibitors is provided. Also provided are a method of applying a multi-layer coating system and an article comprising a coating system.

A composition for forming a resist underlayer film containing a solvent and polymer comprising a unit structure (A) represented by formula (1) and/or formula (2). The composition is capable of forming a hydrophobic underlayer film that has a high contact angle with pure water and exhibits high adhesion to an upper layer film, thereby being not susceptible to separation therefrom, while meeting the requirement of good coatability, the composition being also capable of exhibiting other good characteristics such as sufficient resistance to a chemical agent that is used for resist underlayer films.

A sandwich-type graphene composite structure formed of carbon-coated silicon nanoparticles and graphene, and a method for manufacturing the same are provided. The sandwich-type graphene composite structure is formed of a carbon-coated silicon graphene through an environmentally friendly filtration process. The formed sandwich-type graphene composite structure relieves the volume expansion of the silicon. In addition, the carbon coated on the silicon surface improves electrical conductivity and may be used as a high-capacity anode material.
