  • HOT MELT PRESSURE SENSITIVE ADHESIVE COMPOSITIONS AND ARTICLES INCLUDING THE SAME
    Publication number: 20220387661
    Abstract: The HMPSA compositions of this invention include from 10% by weight to 35% by weight of a styrenic block copolymer, from 10% by weight to 60% by weight of a near white rosin ester tackifying agent having a neat Molten Garner Color of no greater than 2, and from 28% by weight to 45% by weight of a plasticizer. The HMPSA compositions are especially useful as positioning adhesives adhering well to both cotton and microfiber.
