Butoxyl is a neutral colorless liquid with a faint odor. It is miscible with the common organic solvents; its solubility in water is very low. Butoxyl contains no ethanol and meets the requirements of DIN 53 246 (esters of acetic acid).
Dissolving power: The following substances are freely soluble in Butoxyl: rosin, glycerol resin esters, mastic, chlorinated rubber, cellulose ethers (ethyl and benzyl cellulose), nitric acid esters of cellulose (nitrocellulose, celluloid), butyric acid esters of cellulose (cellulose acetate butyrate), polystyrene (coatings), vinyl chloride/vinyl isobutyl ether copolymers, vinyl chloride/vinyl acetate copolymers, vinyl chloride/vinyl propionate copolymers, polyvinyl ethyl ethers, polyvinyl butyral, highly acetalized, polyvinyl acetate, methacrylates, aromatic-formaldehyde resins, ketone resins, phenol-formaldehyde resin, rosin-modified phenolic resins, carbamic acid ester resins, urea-formaldehyde resins, melamine resins, alkyd resins, Soft Resin KTN, chlorodiphenyl resins, epoxy resins, chlorinated polypropylene, heavy machine oil, linseed oil, linseed-stand oil, castor oil, wood oil, spindle oil, dioctylphthalate, triscresyl phthalate (TCP), tris-2-chloroethyl phosphate and phthalic acid polyglycol esters. Coumarone resins, polyvinyl chloride (postchlorinated) and waxes are freely soluble only if heated.
The following substances are sparingly soluble: bitumens, coal tar pitch, acaroid resin, unplasticized resols; natural rubber, acetic acid esters of cellulose (acetyl cellulose) and polyvinyl chloride (PVC) may swell in Butoxyl.
The following substances are insoluble: dammar, shellac, neoprene, polyisobutylene, polyvinyl butyral (low degree of acetalization), polyvinyl alcohol, polyvinyl carbazoles, polyethylene, polypropylene grades, polytrifluoromonochloroethylene, polytetrafluoroethylene, polyamides, polyterephthalic acid glycol ester, polyacrylonitrile and polyacetals.

Because of its faint odor and excellent dilutability with ethanol and hydrocarbons, Butoxyl is highly suitable for brush-applied paints. It prevents the familiar blushing or milky opalescence of the drying paint films caused by thinners even when used in fairly large amounts. Butoxyl in combination with ethanol does not attack rubber and can therefore also be used for paints applied by machine (rubber rollers). An addition of Butoxyl gives spray paints a smooth surface and high gloss even when ester resins and oxidatively curing resins are used. Because of its low volatility it is best added to spray paints in amounts of no more than 5 – 10 %. Butoxyl brings great advantages when used in stoving enamels because of its low volatility, promoting flow and gloss of the paint films. Butoxyl can be used as a solvent in isocyanate and epoxy containing systems. In high-solids paints Butoxyl can be employed as a solvent to lower the viscosity.
