Franklin unveils alternative to UV-curable and solvent-based PSAs

Franklin unveils alternative to UV-curable and solvent-based PSAs

Franklin Adhesives & Polymers, a division of Franklin International, has introduced Acrynax, a line of acrylic polymer hot melt pressure sensitive adhesives that is claimed to be environmentally friendly.  

The Acrynax line offers an alternative to solvent-based adhesives, which can be damaging to the atmosphere and typically must be recovered or safely oxidized – often at additional cost to the manufacturer. Acrynax adhesives eliminate the need for solvent handling. 

As a fully reacted hot melt adhesive, Acrynax can be used in the same machinery as rubber-based hot melts – which contain agents that interfere with UV curing – without requiring expensive and time-consuming equipment clean-outs. Because they are fully cured, Acrynax adhesives are said to allow for higher coating speeds than either solvent-based or water-based adhesives.  

All Acrynax products are claimed to 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, ultraviolet 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 a 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’ line of removable, permanent and specialty pressure adhesives, offered under the Covinax, Micronax and, now, Acrynax families.
