Franklin Adhesives & Polymers has launched its new Micronax microsphere technology. It provides what the company says is “the highest degree of repositionability of any type of pressure sensitive adhesive available.”

Micronax microsphere technology uses particles – or spheres – that are larger than particles found in conventional emulsion adhesives. The larger size of these still-microscopic spheres has a big impact on adhesive tack, says Mike Witte, business manager, pressure sensitive adhesives. The spheres create a discontinuous adhesive surface that limits physical contact with a substrate, resulting in easy removability and stable adhesion over time.

Micronax microsphere adhesives have been approved for FDA indirect food contact and, therefore, have applications in the food packaging industry. To meet diverse applications, Franklin Adhesives & Polymers has developed two lines of Micronax microsphere adhesives: the 240 and 250 series. Adhesives in both are acrylic based and available in a broad range of viscosities, with performance properties tailored to customers’ needs. The 250 series is distinguished by its much higher solids content for reduced drying time when applied, and higher productivity. Custom formulations also can be developed.

“Micronax microsphere adhesives are one of the most exciting developments to emerge from our R&D lab,” says Witte. “We are thrilled to expand our PSA offerings to include unique Micronax technology and to continue offering our expertise and service to meet each customer’s specific adhesive requirement.”
