摘要:
The invention therefore provides a method of improving print performance in a paper product comprising applying a coating composition comprising (i) a pigment and (ii) a starch dispersion of discrete crosslinked native starch particles in an aqueous liquid, wherein the particle size of the starch particles in the starch dispersion ranges from about 40 nm to about 400 μm, to the paper product, wherein the print performance of the paper product is improved. In one embodiment, the coating composition comprises a solids content of from 5 to about 75% weight and comprises (i) about 100 parts by weight of pigment, and (ii) about 1 to about 300 parts by weight of starch, all based on dry weight.
摘要:
A water-based hydrogel polymer coating and a method of application to natural rubber or other elastomeric latex products are provided. The water-based hydrogel polymer is mixed with a blend of at least one elastomeric material to provide a hydrogel polymer blend composition. The water-based hydrogel polymer blend composition is applied in a single application to an elastomeric article, such as gloves, without additional solvents in the polymer blend composition and without a separate acid or chemical priming step. The water-based hydrogel coating herein provides increased lubricity to facilitate improved wet and dry donning of the elastomeric article.

The present invention is directed to antistatic elastomeric articles and methods of making the same. The articles can be single layered or multilayered. The single layered articles possess desirable antistatic properties and desirable properties of comfort and feel. The multilayered articles have an outermost layer/surface that possesses desirable antistatic properties and an innermost layer/surface that exhibits desirable properties of comfort and feel. In preferred embodiments, the elastomeric articles are made form a nitrile/natural rubber blend. Articles of the present invention have antistatic properties measured as having a surface resistivity below about 1014 Ω/sq and a static decay time of less than about 60 seconds.

摘要:
A latex of a cyano-bearing copolymer rubber which contains units derived from an α,β-ethylenically unsaturated nitrile monomer in an amount of 10 to 30% by mass and has an iodine number of 250 or below, a Mooney viscosity (ML1+4, 100° C.) of 10 to 120, and a difference (ΔTg) between extrapolated glass transition initiation temperature (Tig) and extrapolated glass transition ending temperature (Teg) of 15° C. or below as determined by differential scanning calorimetry; and fluid treatments for bonding and adhesive compositions, containing the latex. The adhesive compositions are excellent in heat resistance, oil resistance, and adhesion to vulcanized rubbers, and exhibit tackiness.
