Our “What’s New” department took a break for the summer months not returning until now but chock full of new things to report. One of the choices is related to a February “What’s New” report on a class of dye compositions referred to as visible opaques (7276A through F).These compositions were and are used to block out visible light and varying amounts of the near infrared (NIR). They were designed for injection molding of polymeric resins (polycarbonate, PMMA, polyethylene, etc.). It did not occur to us that visible opaque compositions would also be needed in coating applications. When 7276 A through F were tried as coatings, they performed poorly because certain of the dyes in the series would not dissolve in the coating solvents. We now want to announce that visible opaque coatings are available. Typical of this new class of coatings is 8484. This composition blocks all visible light and part of the NIR up to 800nm. We offer it as a liquid coating or ink that is fully formulated. It can be used in dip coating and silk screen coating. With some solvent dilution it can be used as a spray coat or even in spin coating. Contact us. We are full of information and enthusiasm, ready to share it with you so that you get to like this product.
