Composition of water based coating with a low content of volatile organic compounds and high resistance to dirt handle, and, use of water based coating
The present invention relates to water-based coatings compositions containing low volatiles and high resistance to the dirt grip. Such compositions contain conventional low VOC coalescing latexes which favor the evolution of hardness of films of inks and films of polymers by providing coatings with high resistance to the catch of dirt that can be used in various applications. Such coalescents are predominantly diesters with a boiling point greater than 260° C., preferably boiling point greater than 280° C., and molecular weight between 230 and 342 atomic mass units prepared from diacid and alcohol or monoacid reactions and diols.

Bugphobic and icephobic compositions with fluid additives
Some variations provide an anti-fouling segmented copolymer composition comprising: (a) one or more first soft segments selected from fluoropolymers; (b) one or more second soft segments selected from polyesters or polyethers; (c) one or more isocyanate species possessing an isocyanate functionality of 2 or greater, or a reacted form thereof; (d) one or more polyol or polyamine chain extenders or crosslinkers, or a reacted form thereof; and (e) a fluid additive selectively disposed in the first soft segments or in the second soft segments. Other variations provide an anti-fouling segmented copolymer precursor composition comprising a fluid additive precursor selectively disposed in the first soft segments or in the second soft segments, wherein the fluid additive precursor includes a protecting group. The anti-fouling segmented copolymer composition may be present in an anti-ice coating, an anti-bug coating, an anti-friction coating, an energy-transfer material, or an energy-storage material, for example.
TAGGING OF FRACKING SAND
Disclosed is a process for on- and off-site tagging of fracking sand and a composition of matter capable of being utilized in that process. The composition of matter includes a linker polymer conjugated to a rare earth particle. The method involves forming two mixtures, a first involving mixing a linker polymer conjugated to a rare earth particle into an aqueous blend of fracking sand, and a second involving an activated amine terminated polymer in an aqueous solution. The second mixture is then added to the first mixture, and covalent amide bonds are formed.

An elastic barrier coating composition includes an aqueous dispersion of core-shell particles and an elastomeric polymer that is different from the aqueous dispersed core-shell particles. The aqueous dispersion of core-shell particles include an aqueous medium and core-shell particles dispersed in the aqueous medium. The core-shell particles have a polymeric core at least partially encapsulated by a polymeric shell in which the polymeric shell includes: (i) a barrier segment comprising aromatic groups and urethane linkages, urea linkages, or a combination thereof; and (ii) an elastomeric segment that is different from (i). The barrier segment includes at least 30 weight % of the polymeric shell based on the total solids weight of the polymeric shell. Further, the polymeric shell is covalently bonded to at least a portion of the polymeric core.
Low-friction and low-adhesion materials and coatings
Disclosed are materials that possess both low adhesion and the ability to absorb water. The material passively absorbs water from the atmosphere and then expels this water upon impact with debris, to create a self-cleaning layer. The lubrication reduces friction and surface adhesion of the debris (such as an insect), which may then slide off the surface. The invention provides a material comprising a continuous matrix including a polymer having a low surface energy (less than 50 mJ/m.sup.2) and a plurality of inclusions, dispersed within the matrix, each comprising a hygroscopic material. The continuous matrix and the inclusions form a lubricating surface layer in the presence of humidity. The material optionally contains porous nanostructures that inject water back onto the surface after an impact, absorbing water under pressure and then releasing water when the pressure is removed. The material may be a coating or a surface, for example.
