A water-based primer, used primarily on wood. A primer (/ ˈ p r aɪ m ər /) or undercoat is a preparatory coating put on materials before painting.Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted.
oil ground was a lean lead-based primer, no longer used due to being a health hazard, modern "oil ground" is actually alkyd; genuine gesso ground is a lean ground typically used on top of the boards; half-chalk ground; acrylic ground is made of acrylic resin with titanium white pigment (a "clear gesso" is actually an acrylic without the pigment).
A ground is waxy material applied to the surface of a metal etching plate. A metal etching plate is a piece of sheet metal , usually copper , zinc , steel , or aluminium . The ground resists the acid or mordant which is used for etching, protecting areas of the metal plate.
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 ...
the cleaned metal part is heated to the recommended FBE powder application temperature, and the application and curing stage. The advantage of pipe and rebar is that their round shape allows continuous linear application over the exterior surface, while the parts are moved in a conveyor through the powder application booth, ensuring high ...
Solder is a metallic material that is used to connect metal workpieces. The choice of specific solder alloys depends on their melting point, chemical reactivity, mechanical properties, toxicity, and other properties. Hence a wide range of solder alloys exist, and only major ones are listed below.
Detonating cord (also called detonation cord, detacord, detcord, blasting rope, or primer cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite). With the PETN exploding at a rate of approximately 6,400 m/s (21,000 ft/s), any common length of detonation cord appears to explode instantaneously.
Petroleum-based rust-inhibitors provide several benefits, including the ability to creep over metal, covering missed areas. [citation needed] Additionally, a petroleum, solvent-free rust inhibitor remains on the metal surface, sealing it from rust-accelerating water and oxygen. Other benefits of petroleum-based rust protection include the self ...
