CATIONIC ELECTRODEPOSITION COATING COMPOSITION AND METHOD FOR ELECTRODEPOSITION COATING
The present disclosure is a cationic electrodeposition coating composition comprising an emulsion particle (A) containing a Michael addition reaction donor component and an emulsion particle (B) containing a Michael addition reaction acceptor component wherein a Michael addition reaction catalyst (C) is contained in the emulsion particle (A) or the emulsion particle (B) or is contained in the cationic electrodeposition coating composition by being microencapsulated.
BEAD MAKER AND DECORATOR
An apparatus, kit, and methods for forming a bead between bead-forming blocks having internal bead-forming channels are provided. The bead-forming channels of adjacent bead-forming blocks are slidably engaged to manipulate a measured amount of modeling compound between the bead-forming blocks and within an internal space between the opposing channels. In one embodiment, the bead-forming blocks maintain orientation with respect to an axis of travel based on a block guide. Further, the measured amount of modeling compound is determined using an integrated measuring feature coupled to at least one of the pair of bead-forming blocks. The internal volume of an integrated measuring feature corresponds to a threshold amount of modeling compound for manipulating between the pair of blocks and forming a bead while contacting at least a portion of the mated bead-forming channels. In further aspects, a molded bead may be coated with a multicomponent bead-coating mixture. Multi-component bead-coating mixtures and methods of using thereof are provided.
Basecoat acid neutralization through inorganic salts
The present invention provides a system comprising an allophanate composition comprising a neutralized polyol, a polyuretdione resin, a tertiary amine catalyst, an additive package, and a reducer; and a neutralized basecoat comprising an inorganic salt and a pigment. The present invention further provides a method of making an allophanate system comprising combining a neutralized polyol with a polyuretdione resin in the presence of a tertiary amine catalyst, an additive package, and a reducer to produce an allophanate composition, and contacting the allophanate composition with a neutralized basecoat comprising an inorganic salt and a pigment. The system may be used to make coatings, adhesives, castings, composites, and sealants in which clear-coating on neutralized pigmented basecoats is much improved in comparison to coating on non-neutralized basecoats.

METHOD OF MAKING NANOPARTICLE COLLOID AND NANOPOROUS LAYER
This application features a method of forming a nanoporous layer. The method includes steps of reducing metal ions in a reverse micelle phase composition to form nanoparticles, removing surfactant from the composition to form clusters of the nanoparticles, dispensing the composition including the nanoparticle clusters dispersed in a liquid on a substrate, and drying to form the nanoporous layer. The nanoporous layer includes nanoparticles deposited to form a three dimensional network of irregularly shaped bodies. The nanoporous layer also includes a three dimensional network of intercluster spaces that are not occupied by the three dimensional network of irregularly shaped bodies.

STIMULI-RESPONSIVE COLOR-CHANGING FUNCTIONAL COATING, PREPARATION METHOD AND APPLICATION THEREOF
A stimuli-responsive color-changing functional coating is prepared from the following raw materials: an epoxy resin, a furanone pigment, an amine curing agent, and a solvent. The furanone pigment is an organic conjugated conductive molecule. The amine curing agent reacts with the furanone pigment to form a cross-linked molecule containing a hydrogen bond that can exhibit excellent electron transition behaviors. Moreover, as the cross-linked molecule is unstable, it may give rise to electron transitions with different properties under different stimulus conditions, imparting a color-changing property to the coating that allows the coating to have different colors in response to different environmental stimuli. Experimental results show that the stimuli-responsive color-changing functional coating in the present invention has thermochromic, ultraviolet-photochromic and strongly acidochromic properties, and is responsive to diverse color-changing stimulus conditions with a wide color-changing range.
Coating composition comprising submicron calcium carbonate-comprising particles, process to prepare same and use of submicron calcium carbonate-comprising particles in coating compositions
A coating composition comprising an aqueous dispersion of submicron natural ground calcium carbonate particles contained in a liquid binder, wherein the resultant coating may constitute either a clear coat or a glossing and opacifying coating, depending upon the presence of certain additives such as a mineral pigment (e.g., TiO.sub.2). The composition is characterised in that comprises, in the case of a clear coating, at least one ground natural calcium carbonate having a median diameter of between 0.05 and 0.15 m, while in the case of a glossing and opacifying coating, at least one ground natural calcium carbonate having a median diameter of between 0.05 and 0.3 m and at least one pigment having a refractive index of greater than or equal to 2.5.
