Properties
Solvenon DPM is a mixture of isomers. It is a clear, high-boiling, hygroscopic, mobile, low-volatility liquid with a mild odour and is miscible with water and common organic solvents.By virtue of the ether and alcohol groups in the constituent isomers,Solvenon DPM is an excellent solvent for many of the raw materials that are used in coatings, e. g. resins and binders. An important feature of Solvenon DPM is the fact that it acts as a solubilizer in many aqueous coating systems. It possesses the typical properties of ethers and alcohols. For instance, it reacts with acids (to form esters), oxidizing agents (to form the corresponding aldehydes or carboxylic acids), alkali metals (to form alcoholates) or aldehydes (to form acetals). Solvenon DPM may form peroxides with atmospheric oxygen.
