The fundamentals of powder coating formulating and the associated performance of different resin chemistries will be introduced, including examples of typical end uses for each chemistry. Formulation components, including resins and crosslinkers, reactive additives, nonreactive additives, colorant pigments and extenders will be explained on how and why they are used. The presentation will wrap up with a summary of the philosophy of formulating a successful powder coating.
A powder coating formulator often has to match a liquid paint color standard for similar performance and very close shade. The two technologies (powder & liquid coatings) are significantly different, and the number of options for liquid formulations are lot more than those for powder coatings. Over 100 pigments in yellow, orange & red hues alone are suitable for liquid coatings whereas that number dwindles down to 30 or less for powder coatings. High surface area pigments (violet, blue & green hues) disperse easily in liquid systems whereas pose a real problem in powder coatings. A good understanding of pigment limitations (heat stability, durability, gloss and flow properties) can minimize the performance difference, and metamerism, necessary for customer satisfaction. Spectrophotometric measurements of the standard & the match, are very helpful to achieve a satisfactory formulation. Otherwise, many trials and money is wasted without a successful outcome. In this presentation, establishing the proper standard, and selection of pigments to arrive at an optimum formulation will be discussed. Importance of spectrophotometric data to understand and resolve metamerism between standard and match will also be elaborated.
This presentation gives a general overview of engineered synthetic silica in the marketplace. The overview will cover types of silica, general manufacturing, their particle characteristics and impact in coatings. The presentation will then focus on the use of the fumed metal oxides as fluidization additives for powder coating and how they disrupt the various forces that causes caking of the powders.
This presentation will take a deeper look into the processes of pre-mixing, metallic blending and metallic bonding, analyzing how the mixing process can be improved in order to achieve the best final product, through a complete automatic control. It will also introduce attendees to a new function developed by Promixon R&D department to determine the right melting temperature directly during the mixing phase: the EASYBOND function.
You want to learn more about infrared… but electric vs gas, wavelength and line of sight issues have you confused. Can you believe the claims? Is it hard to work with? Infrared is not always well known or understood even though it is well suited for powder applications. Its unique properties and low operating costs make it well suited for full finishing systems or as a boost to significantly increase throughput and save money. As well, infrared also has significant environmental benefits that are not well understood yet. How much then does it actually save you vs convection? This discussion is a balanced presentation of how infrared works and the pros and cons of each of the heating technologies (convection, electric infrared and gas catalytic infrared). Learn how infrared is generated, how it works and when it might best work for you and why.
