Everything You Need To Know About Chemical Film Coatingby Mohit J. White Hat Link Building Services
Chemical film or chromate conversion coating is an exceptional method to achieve corrosion-resistant finish and that too without affecting the properties of the metal. Further, the coating is also applied onto different parts prior to primer or paint so as to increase adhesion. Due to the benefits that chemical film coating offers, this technique has become an essentiality for several industries including electronics, optics, mechanical, electrical, aerospace and defense too.
What Are The Different Types of Chemical Film Coating?
Many people often have a misconception that every form of chemical film is just the same, however they do vary significantly and are usually categorized into different types according to their composition and purpose of application. These are:
• Category 1: Based on hexavalent chromium, as a result of which the process is termed as chromate conversion. Though this category was known to be a standard practice prior to 21st century, but soon advanced methods made their way and led to the development of other classes of coating.
• Category 2: In this category, the coating does not have hexavalent chromium, rather this chemical is replaced with other potent ingredients such as trivalent chromium, zirconium, and titanium.
• Class 1A: The class indicates that the purpose of chemical film coating services is to provide the highest level of protection against corrosive substances, which is why the coat tends to be thicker and darker. It even indicates that the coating can work as a primer for either decorative or utilitarian purposes. For example, specialized chemical coatings are used in military on their equipment and vehicles.
• Class 3: This coating aids in minimal to no interference with the conductivity of the metal, while providing protection against corrosion. Let's say, you require chemical film for electrical components then Class 3 coating will be an appropriate choice.
What Determines The Final Outcome of Chemical Film Coating?
There are four factors that influence the final outcome of chemical film coating- (a) type of material that you want to coat, (b) quality and purity of the material, (c) surface quality (where the coating has to be applied and (d) class of chemical film.
Hence, in order to achieve expected results, you need to focus on the aforementioned factors and then select the ultimate company for professional services. Consider a specialist who provides comprehensive range of services including chemical film, copper plating, cadmium plating and more, adheres to the highest industry practices and guarantees consistent results every single time.
At the end of the day, the true benefits of plating services can be witnessed when you count on a trusted professional for the purpose.
