Solvent Leaching Effects on Aged Oil Paints

This paper presents a survey of significant developments in research on the leaching of oil paint films by organic solvents, from the first systematic investigations carried out in the 1950s to more recent “clinical” studies involving the sampling and analysis of paintings during treatment. Key studies are discussed in the context of an improved knowledge of oil paint chemistry that has develop...

Measurements of Complex Dielectric Constants of Paints and Primers for DSN Antennas: Part II

In Part I of this article, complex dielectric constant values in the frequency range of 24 through 34 GHz were presented for paints and primers currently being used as well as for candidate replacements. Tables of complex dielectric constant values were given for (1) Triangle no. 6 white flat paint, (2) zinc chromate primer, (3) 18FHR6 white water-based paint, and (4) 283 water-based (Aquapoxy)...

Synthesis and Characterization of Anionic Polyurethane Dispersants for Waterborne Paints

Anionic polyurethane dispersants APUDs were used as dispersing agents in formulation of waterborne paints. The APUDs were synthesized by three steps. In the first step, macromonomer diisocyanate having carboxylic acid was prepared by isophorone diisocyanate IPDI, dimethylol propionic acid DMPA in presence of acetone as solvent and dibutyltin dilaurate DBTDL as catalyst. Then, carboxylic polyure...
