FRANKLIN ADHESIVES & POLYMERS: Hot-Melt Adhesives (12/15/09)
Franklin Adhesives & Polymers®, a division of Franklin International, has introduced Acrynax® adhesives, a line of acrylic polymer hot-melt pressure-sensitive adhesives that is good for both the environment and the manufacturer’s bottom line.
The Acrynax line offers an environmentally safe alternative to solvent-based adhesives. Solvents can be damaging to the atmosphere and typically must be recovered or safely oxidized – usually, at an additional cost to the manufacturer. Acrynax adhesives eliminate the need for this expensive solvent handling.
Acrynax also offers a cost-effective alternative to UV-curable pressure-sensitive hot melts. First, as a fully reacted hot-melt adhesive, it can be used in the same machinery as rubber-based hot melts – which contain agents that interfere with UV-curing – without requiring expensive, time-consuming equipment clean-outs. Further, because they are fully cured, Acrynax adhesives allow for much higher coating speeds than either solvent-based or water-based adhesives. High coating line speeds enable maximum productivity at the plant.
In addition to offering manufacturers some strategic cost efficiencies, Acrynax acrylic polymer hot melts also offer versatility for diverse applications. All Acrynax products exhibit good adhesion to a variety of materials, including polyester, glass, steel, aluminum, vinyl, fabric, non-wovens and paper. They are optically clear, skin-friendly and highly resistant to water, solvent, UV light and many plasticizers.
Acrynax also can be used as a modifier of other adhesives, imparting benefits of acrylic chemistry to those products.
The new Acrynax line offers four formulas to meet specific product requirements. Two higher-viscosity polymers, Acrynax 11588 and Acrynax 11891, also have higher shear strength. The lower-molecular-weight polymer Acrynax 4326 has higher peel strength, quick stick and loop tack values. And Acrynax 11891 is a cross-linked polymer that offers an excellent balance of shear, tack, peel and cold flow resistance – as well as greater plasticizer resistance than the linear polymers that comprise the other three Acrynax products.
The new Acrynax adhesives expand Franklin Adhesives & Polymers’ broad line of removable, permanent and specialty pressure adhesives, offered under the Covinax®, Micronax® and, now, Acrynax families. These adhesives offer varying degrees of peel, tack and shear for virtually any end use, from labels for pharmaceutical containers to automotive applications.
