Abstract
A coating reducers containing low volatile organic compounds (VOCs) to improve adverse environmental impacts, where the reducers may be water or solvent based and include mixtures of VOC exempt solvents and/or low vapor pressure (LVP) solvents and paints, lacquers, and varnishes diluted with the reducers.
Claims11
A solvent based reducer composition comprising:
- less than 100 wt. % and greater than 95 wt. % of at least one low vapor pressure (LVP) solvent selected from the group consisting of a normal paraffin, an isoparaffin, a cycloparaffin, and mixtures thereof;
- and
- greater than 0 wt. % and less than 5 wt. % of a volatile organic compound (VOC) consisting essentially of ethyl lactate, naphtha, an alkanolamine, a glycol, a polyol, or mixtures thereof,
- wherein the composition contains no water or aqueous components, and
- wherein the composition is used to reduce oil based coating compositions.
2 more elements
A solvent based reducer composition comprising:
- from 40 wt. % to 99 wt. % of a solvent system comprising methyl acetate, t-butyl acetate, a low vapor pressure (LVP) hydrocarbon or a mixture of LVP hydrocarbons, or mixtures thereof;
- from 1 wt. % to 40 wt. % of secondary solvents consisting essentially of parachlorobenzotrifluoride, a chlorinated hydrocarbon, a fluorinated hydrocarbon, a halogenated aromatic hydrocarbon, or mixtures thereof,
- greater than 0 wt. % to 99 wt. % of a dibasic esters, a methyl ester of a C12-C36 carboxylic acid, a fatty acid, a salt of a fatty acid, a glycol, or mixtures thereof based on the wt. % of the solvent system and the secondary solvents;
- greater than 0 wt. % to 25 wt. % of nonexempt or partially exempt volatile organic compound selected from the group consisting of tetrahydrofurfuryl alcohol, an alkanolamine, naphtha, and mixtures thereof based on the wt. % of solvent system and the secondary solvents;
- and
- greater than 0 wt. % to 5 wt. % of additives to improve the properties of the composition selected from the group consisting of a thickener, a surfactant, a fragrance, ethyl lactate, a solid, and mixtures thereof based on the wt. % of the solvent system and the secondary solvents,
- wherein the LVP hydrocarbon or LVP hydrocarbons are selected from the group consisting of a normal paraffin, an isoparaffin, a cycloparaffin, and mixtures thereof, and
- wherein the composition is used to reduce oil based coating compositions.
