摘要:
The present invention relates to a stable aqueous dispersion of thermoplastic polymer particles imbibed with a thermosettable compound. The polymer particles are characterized by having a sufficient concentration of anti-agglomerating functional groups to stabilize the latex against agglomeration. The dispersion is useful as one part of a two-pack formulation.
摘要:
The present invention provides compositions that enable excellent early hardness development in coating applications, the compositions comprising a blend of one or more copolymer, pA, having a Tg of 20° C. or higher, and one or more polyurethane copolymer in aqueous dispersion, pB, together with one or more additive chosen from a coalescent having a normal boiling point of from 150° C. to no greater than 300° C., a naturally derived plasticizer, and mixtures thereof. The polyurethane copolymer comprises at least 40 wt. %, based on the weight of polyurethane solids, of: (i) a first polyol having a molecular weight of at least 850, wherein the first polyol is a polyether polyol, or (ii) a second polyol chosen from a polyester, a polycaprolactam, a polycarbonate and a combination thereof, wherein the second polyol has a molecular weight of at least 1,500, or (iii) a combination of one or more first polyol and one or more second polyol. The compositions may be ambient curable.
摘要:
A paper having an improved print quality comprises a paper substrate having a surface with a surface roughness of less than 6 microns and a surface gloss of 5-80% which surface has been coated with a light-weight, low solids content, top coat. The top coat may comprise (i) a rheology modifier/binder component and at least one pigment or (ii) at least one binder coated pigment. The top coat provides a significant improvement to the delta gloss of the so-treated paper.

The present invention provides compositions that enable excellent early hardness development in coating applications, the compositions comprising a blend of one or more acrylic emulsion copolymer, pA, having a Tg of 20° C. or higher, and one or more acrylic emulsion copolymer, pB, having a Tg at least 15° C. lower than that of pA, together with one or more additive chosen from a coalescent having a normal boiling point no greater than 300° C., a naturally derived plasticizer, and mixtures thereof. The compositions may be ambient curable.
摘要:
Ink compositions having increased stability and increased jettability with the addition of specific surfactants, including alkyl ether sulfates and ethoxylated mercaptans, are provided. The remainder of the ink composition comprises a suitable carrier vehicle, which typically contains water, alcohols, surfactants, humectants and optionally a resin component.
摘要:
The present invention relates to a process for imbibing a step-growth polymer into thermoplastic latex particles and a composition made by such a process. The composition is useful, for example, as a coating, an adhesive, a sealant, a primer, a caulk, a stain, or a filler for a variety of substrates.
