2-Butoxyethanol, solvent system

From the above it will be clear that butoxyethanol is often the preferred single solvent, not only in normal aqueous but also in electrodeposition paints. However, for the latter application also other solvent systems are used, for instance blends of ethoxyethanol/butoxyethanol with hexoxyethanol and ethoxyethanolacetate as film coalescent in ratios of approx. 1/1/1. Sometimes propoxyethanol is used instead of ethoxyethanol and in some formulations 10-15% of the solvent blend is isopropanol, which is added because of its volatility and to optimise the partitioning of the solvent blend over the aqueous and organic microphase of the electrodeposition paint. 

Butoxyethanol and 2-butoxyethanol acetate do not seem to have effects on the immune system of animals. Like many solvents, 2-butoxyethanol causes nervous system effects in animals. 

Two solvents used in this evaluation, 2-butoxyethanol and 2-(2-butoxyethoxy) ethanol, were the most versatile. Except for the film appearance of the trimellitic alkyd, satisfactory coating systems could be made with each of the three resins. The 2-butoxyethanol has slightly lower viscosity and lower cost. On the other hand 2-(2-butoxyethoxy)-ethanol gave slightly higher rupture voltages. With the acrylic resin and... 

Rocklin (62) made a careful study of the effect of humidity and other ambient conditions on the evaporation of ternary water-solvent blends. The problem of evaporation of these systems is illustrated by Figure 13 on the system water-butanol-butoxyethanol. This particular figure shows trends only and is not intended for exact predictions. In these studies, the author employed a "central composite experimental design" that allowed a large number of variables to be investigated simultaneously and economically by using a modest number of experiments to achieve significant results.

Novolac resins are broadly used in electronics because their functionality higher than two increases the crossimkmg density and yields cured resins exhibiting enhanced chemical and physical properties. Mixtures of epoxy resins and phenol novolacs 61 are excellent structural adhesives in the aerospace industry. However, the phenolic hydroxyl groups are not very reachve at moderate temperatures and most systems include catalysts or accelerators. Classical adhesive compositions are prepared by mixing a solid epoxy resin, t5rpicahy an epoxidized phenol novolac resin (60 parts), a phenol novolac resin (40 parts), a solvent such as 2-butoxyethanol or butylcehosolve acetate, an imidazole catalyst, and silver flakes.
