The present invention provides a binder composition comprising a first binder comprising by dry weight based on total dry weight of the first binder, from 5% to 98% of polymer particles, from 0.3% to 10% of a first polysaccharide, from 0.01% to 5% of a crosslinker, from 0.3% to 6% of a water-soluble metal cation, and from 0.05% to 3% of a cationic polyelectrolyte. The binder composition may further comprise a second binder comprising by dry weight based on total dry weight of the second binder, from 0.3% to 20% of the first polysaccharide, from 0.5% to 20% of a second polysaccharide. And in that case, the wet weight ratio of the first binder to the second binder is from 1:20 to 20:1. The present invention further provides a paint formulation comprising the binder composition.

The present disclosure describes aqueous adhesives comprising, inter alia, adhesives and saccharide fatty acid esters, particularly unsaturated fatty acid esters (uSFAE), including aqueous adhesive compositions containing such a combination and where such aqueous adhesive compositions show improved water resistance compared to adhesives which do not contain said uSFAE. Articles of manufacture comprising said aqueous adhesive compositions are also described.

Disclosed herein are styrene butadiene rubber latex compositions with high solids content and methods for making and using these compositions. The method for making the styrene butadiene rubber latex compositions can include mixing a seed, a styrene, an initiator, a base, a surfactant, and a solvent; adding a first portion of 1,3-butadiene to make a first reaction mixture; heating the first reaction mixture for a first reaction time to make a first styrene butadiene rubber latex; mixing the first styrene butadiene rubber latex, a styrene, a base, an initiator, a surfactant, and a solvent; adding a second portion of 1,3-butadiene to make a second reaction mixture; and heating the second reaction mixture for a second reaction time to make a second styrene butadiene rubber latex, where the second styrene butadiene rubber latex has a solids content higher than that of the first styrene butadiene rubber latex.

An aqueous adhesive for rubber includes rubber latex and an ammonium-salt-based vulcanization acceleration aid. An amount of the ammonium-salt-based vulcanization acceleration aid contained in the aqueous adhesive is preferably not less than 0.01% by weight and not greater than 5.0% by weight in terms of solid content. An aqueous adhesive for a ball includes rubber latex as a main component. A content of an inorganic filler in the aqueous adhesive is not greater than 0.1% by weight in terms of solid content. A ball 2 includes a hollow core 4 obtained by crosslinking a rubber composition that contains a vulcanizing agent. The core 4 is formed of two hemispherical half cores. The two half cores are adhered to each other by using the aqueous adhesive for a ball.
