Viscosity Profiles of Solvent Based Paints: Their Measurement and Interpretation
نویسنده
چکیده
A single point viscosity measurement has been proven meaningless in determining the rheological and application properties of a paint. Paints having the same “one point“ viscosity can hove different settling, sag, and leveling properties. These rheological differences are graphically depicted by means of viscosity profiles obtained through the use of low and high shear rate viscometers. A method to evaluate the flow properties of paints and specifically leveling based on the rheology of sheared paint samples, as a function of time and at variable low, and ultra-low shear rates, is described.

Occupational exposure to water based paint and symptoms from the skin and eyes.
Water based paints contain organic solvents and many additives, such as biocides, surfactants, pigments, binders, amines, and monomers. The chemical complexity may introduce new potential health hazards to house painters, in particular irritative and allergic disorders. This study was performed to compare how house painters experience work with water based paints or solvent based paints, and to...
متن کاملAn optimization study by response surface methodology (RSM) on viscosity reduction of residue fuel oil exposed ultrasonic waves and solvent injection
In this study, response surface methodology (RSM) based on central composite design (CCD) was applied for investigation of the effects of ultrasonic waves, temperature and solvent concentration on viscosity reduction of residue fuel oil (RFO). Ultrasonic irradiation was employed at low frequency of 24 kHz and power of 280 W. The results showed that the combination of ultrasonic waves and solven...

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...

متن کاملOccupational Exposure as a Painter
Paint is a suspension of finely divided pigment particles in a liquid composed of a binder (resin), a volatile solvent or water, and additives that impart special characteristics. The volatile components evaporate from the drying film after application, while the binder holds the pigment in the dry film, causing it to adhere to the substrate. Some high quality, hard gloss paints are referred to...
