Product details

Product Description

MT-300 AM is a series of polyester resin based thermo-setting powder coatings formulated using TGIC. The pigments used in the MT-300 series restrict the field of application of this powder coatings class to interior uses. MT-300 is designed for interior decoration such as, metal furniture, shop fittings, shelves, light fittings. MT-300 AM is a high-quality powder coating designed to meet decorative and functional demands of your specifications. Test results have proven reduction of bacteria and mold up to 99.9%.

Pre-treatment

Aluminium, steel or Zintec surfaces to be coated must be clean and free from grease. Iron phosphate and particularly lightweight zinc phosphating of ferrous metals improves corrosion resistance. Aluminium substrates may require a chromate conversion coating, chrome free pre-treatment or flash anodizing for certain applications. Galvanised steel may require zinc or chromate conversion or sweep blasting. Detailed advice should be sought from the pre-treatment supplier.

Application

MT-300 powder coatings can be applied by corona electrostatic or tribostatic equipment. However the aspect obtained by tribo-static equipment may vary when compared to electrostatic application and/or our colour card. In all application processes the aspect obtained is subject to variation, depending on the method of application (type of gun, nozzle, etc) and the shape/type of component. We recommend that the actual application parameters are adapted and adjusted depending on the type of component and with each powder batch in order to give a finish in accordance with our colour card. The following procedure is given as a guideline when using these finishes. We recommend the use of flat jet spray nozzles. To ensure powder homogeneity, the complete content of the boxes should be emptied completely into the feed hopper. For manual application it is essential to ensure that an even film thickness is applied and in all Instances sinusoidal gun movements should be avoided.
