What is dip coating process
In a dip coating process, a substrate is dipped into a liquid coating solution and then is withdrawn from the solution at a controlled speed. Coating thickness generally increases with faster withdrawal speed. The thickness is determined by the balance of forces at the stagnation point on the liquid surface. A faster withdrawal speed pulls more fluid up onto the surface of the substrate before it has time to flow back down into the solution. The thickness is primarily affectedRead More …
Dip coating methods and techniques
(1)The thickness of the film decided to object to enhance the rate and the viscosity of the liquid paint. Control the viscosity of the liquid paint according to the above requirements, in accordance with the maximum degree in film 30um, depending on the equipment, experiments to determine the appropriate upgrade rate. Click here to enhance the rate evenly be coated object. Enhance the rate and thin film; enhance the rate is slow, the film is thick and uneven. (2)Dip coatingoperationRead More …
The particularity and storage of powder coatings
The powder coating is a new type of solvent-free 100% solid powder coating. It has two categories: the thermoplastic powder coating and thermosetting powder coating. Coating made of special resin, fillers, curing agents and other additives, to a certain proportion of mixed and then by hot extrusion and crushing process of sifting and other prepared from. At room temperature, storage stability, electrostatic spray or fluidized bed dipping, and then the baking heat of melting and solidification, so that the formationRead More …
Anti-corrosion epoxy powder coating – how to play a protective function
The joint application of cathodic protection and corrosion protection layer, allows underground or underwater metal structure to obtain the most economical and effective protection. Usually coated with a protective coating before use, to the metal and dielectric environment electrical insulation isolation, a good coating can protect more than 99% of the structures of the outer surface from corrosion. The pipe coating in the production, transportation and construction, can not absolutely guarantee against any damage to (fill the mouth coating, theRead More …
Hollow microspheres used in high temperature powder coating
Hollow microspheres is a new functional fillers, Until Rrcent years, the characteristics of hollow microspheres were only found in the powder coating application and several well-known powder coating company has used it for mass production, customer feedback is very good. The features is as followed: The hollow microspheres is a thick hollow body with good fluidity,hardness of Ta Mok’s 5-7, and temperature resistant up to 1400 degrees, with the composition of the aluminum silicate it has excellent anti-corrosion to acidRead More …
