Primer reduces the number of paint coats needed for good coverage and even color. A thin layer of paint may still be permeable to water. Water can permeate into the wood and cause warping, mildew, or dry rot. Primer improves the waterproofing of the finish. [4] Primers are not used as part of a wood stain treatment because they obscure the wood ...
Optical bonding, including LOCA and non-liquid OCA tape, are used in a wide range of electronic equipment, especially those with touch panels.The adhesive bonds the touch panel to the main liquid crystal display, and also bonds any protective cover, such as the lens, to the touch panel.
In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied.
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 ...
The below calculated ACIs were done on solvent-based primer containing 350 g/L of solvents and the water-based primer containing 50 g/L of butyl glycol. The values on this chart indicate that the use of mineral spirits based primers would need 6 to 7 air changes per hour requiring significant ventilation. The use of low-odor, isoparaffinic ...
Anionic surfactants such as sodium dodecyl sulfate are most commonly used for stabilizing emulsions because of their affinity for hydrogen bonding with the aqueous medium. Nonionic surfactants are rarely used alone due to their inferior efficiency in creating stable emulsions in comparison to anionic surfactants.
