Abstract
Combinations of essentially nonvolatile, unsaturated ethers and/or esters, and small proportions of low glass transition temperature (Tg) latex reins, as replacements for volatile organic compounds (VOCs) as coalescents and optionally reactive amines (as replacements for conventionally employed volatile amines/ammonia neutralizers, respectively), provides economical, low/no VOC-containing acrylic, styrenic copolymer, polyester, polyurethane and vinyl copolymer latex based coatings, paints, and inks; which out/perform their conventional counterparts.
Claims21
A composition comprising (essentially consisting of) a combination of essentially nonvolatile, in saturated esters/ethers/ether-esters, and a low glass transition temperature (Tg) latex resin.
A coalescent system for latex resins comprising a combination of essentially nonvolatile, unsaturated esters/ethers/ether-esters, and low Tg latex resins.
A coalescent system for acrylic latex resins comprising a combination of essentially nonvolatile, unsaturated esters/ethers/ether-esters, and low Tg latex resin(s), and optionally from 0.2 to about 2 weight % of one or more organometallic based surfactants, and optionally from 0.1 to about 4% of essentially non-volatile reactive amaine(s).
A coalescent system for vinyl, and or vinyl copolymer latex resins comprising a combination of from 1 to 15% essentially nonvolatile, unsaturated esters/ethers/ether-esters, and from 1 to 15% of low Tg latex resin(s), and optionally from 0.1 to about 2 weight % of one or more metallic based surfactants, and optionally from 0.1 to about 4% of essentially non-volatile reactive amine(s).
A coalescent system for styrenic copolymer latex resins comprising a combination of essentially nonvolatile, unsaturated esters/ethers/ether-esters, and low Tg latex resin(s), and optionally from 0.1 to about 2 weight % of one or more metallic based surfactants, and optionally from 0.1 to about 4% of essentially non-volatile reactive amine(s).
A coalescent system for polyurethane latex resins comprising a combination of essentially nonvolatile, unsaturated esters/ethers/ether-esters, and low Tg latex resin(s), and optionally from 0.1 to about 2 weight % of one or more metallic based surfactants, and optionally from 0.1 to about 4% of essentially non-volatile reactive amine(s).
A coalescent system for polyester latex resins comprising a combination of essentially nonvolatile, unsaturated esters/ethers/ether-esters, and low Tg latex resin(s), and optionally from 0.1 to about 2 weight % of one or more metallic based snurfactants, and optionally from 0.1 to about 4% of essentially non-volatile reactive amine(s).
A method for coalescing a latex resin comprising combining a latex resin with an essentially nonvolatile unsaturated ester/ether/ether-ester and a low Tg latex resin.
