Latex paints (emulsion paints British English, not to be confused with latex rubber) are an emulsion of polymer particles dispersed in water. Macroemulsions in latex paint are inherently unstable and phase separate, so surfactants are added to lower interfacial tension and stabilize polymer particles to prevent demulsification.
Comex was the 4th largest paint manufacturer in North America. [38] After Mexican antitrust regulators voted against the deal twice, Sherwin-Williams bought Comex's US and Canadian divisions for $165 million on September 16, 2013. [39] PPG, US-based paint and coating company, acquired Comex's Mexican division for $2.3 billion.
Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...

Menards of East Madison, Wisconsin, pictured in 2012 (closed and relocated to Sun Prairie in 2018) [6] Menards was founded as Menard Cashway Lumber. In the mid-1980s, the "Cashway Lumber" name was dropped and the business became simply known to ...
After liquid paint is applied, there is an interval during which it can be blended with additional painted regions (at the "wet edge") called "open time". The open time of an oil or alkyd-based emulsion paint can be extended by adding white spirit, similar glycols such as Dowanol (propylene glycol ether) or open time prolongers. This can also ...

[6] Founded in 1979 as the Woodscrew Supply Company, the company was acquired in July 1999 by Kingfisher plc , which also owns B&Q , and is listed on the London Stock Exchange .
The second area is that their strength, gap filling properties and excellent adhesion to many materials including timber have created a boom in amateur building projects including aircraft and boats. Normal gelcoat formulated for use with polyester resins and vinylester resins does not adhere to epoxy surfaces, though epoxy adheres very well if ...
Schematic figure of cross-flow membrane emulsification. Membrane emulsification (ME) is a relatively novel technique for producing all types of single and multiple emulsions for DDS (drug delivery systems), solid micro carriers for encapsulation of drug or nutrient, solder particles for surface-mount technology, mono dispersed polymer microspheres (for analytical column packing, enzyme ...
