Butyl acetate is one such reference, and is used in the data below. Note also that water is included as an additional reference, although it is not a suitable electrical cleaning solvent. Note the broad range in evaporation rates of the solvents in Table 1, a factor of 8,000 from the top to the bottom of this list. While TR and NF are expensive specialty solvents, the cost of use is minimized by packaging them in small quantities with just enough to do the job. This question is best answered by studying the combustion properties of fast-dry alternatives.
Flash point is a measure of solvent combustibility often used in shipping and disposal regulations.
The point is, low flash point solvents must be handled with knowledge and care for both legal and safety reasons. While solvents like alcohols can be formulated to dry almost as quickly as trichlor, they have low flash points. Such highly flammable materials are not appropriate for at least some types of field use. Besides the non-flammable TR and NF , American Polywater offers a range of evaporation rates in the electrical cleaners. From the fast but flammable Type FD to the slower evaporating Type HP .
