Ultraviolet radiations have over the years recorded importance following its advancements in availing scratch free products and properties. To this effect, manufacturers and industries have embraced this technology for coating and curing of properties or products. UV coat and cure systems are vast and there is the need to understand what ultraviolet coating is and how to determine whether the coating is ultimately cured using ultraviolet lamps and cure systems. UV coating comes in variety of properties or materials where some are classified under soft, others hard and even slippery among many other arrays of materials. Consequently, professionalism and a high level of expertise are necessitated into ensuring that curing is ultimately achieved. Thus, industries need to capitalize on training their employees ultimately in order to achieve tremendous results. Paints, inks, and adhesive are used during the coating procedure. The below are methodologies to consider and employ in order to determine whether UV curing has positioned ultimately.
Firstly, there is thumb rubbing. Thumb rubbing entails using your thumb to scrub the surface of the coating and determines whether it is cured or not. A cured coat normally smudges your thumb, but with a removable splotch using a soft clothing or paper. Where the splotch is irremovable, then the process is not cured.
The second test to run is a scratch test. Scratching is more intense and should be facilitated using your fingernail. Basically, an ultimately cured coating should resist scratches all through. Therefore, coating should on no occasion scratch off whatsoever. There are two possibilities through which the ink or a coating should scrape off; one, the adhesives used was poor or coating is still not cured.
The final test is the methyl ethyl ketone test. While performing this test, you will need cotton-lint. Use the cotton lint to dip into the methyl ethyl ketone. The moisture cotton cloth should then be double rubbed on the surface of the property. Continue double rubbing until breaking is witnessed. Finally, examine whether there are ink or paint traces on the cloth.
The tests might be negative following the violation or omission of certain requirements like the lamps used and their positioning, the weight and even the coating materials. Generally, one needs to employ keenness when reviewing the set requirements. Failure to adhere to one requirement might ruin the whole curing procedure. Where one lacks skills and exposure, they might avail shoddy coating affecting the curing process as well.
One of the major reasons why a surface might not be fully cured is excessive coat weight. The process has a predefined weight that is overly standardized and there is need to meet the weight requirements. Therefore, weigh the coat again and where it is in excessive, ensure to reduce the unnecessary weight hence speeding the curing process. The positioning of the lamps matters a lot as well and they must be operational and powered copiously.
Finally, the coating used must be of good quality. Therefore, ensure to determine the expiry dates through counterchecking the shelf life defined by the manufacturer. Majority of coatings have six months before expiration.
Keenness must be portrayed through the process and the same keenness employed during the curing process. Lamps must be fully operational and well positioned to avail UV radiations. Therefore, ensure to follow and meet all the set requirements in order to exceptionally fasten the curing process.
