  • Patent number: 12281226
    Abstract: Polymer compositions suitable for modeling are provided as plastisols with a high content of volatile substances, such as bactericidal, aromatizing, and/or flavoring volatiles. Such plastisols are provided by mixing a lyophilic polyamide or lyophilic complex polyester with a plasticizer of moderate to low polarity that includes a bactericidal, aromatizing, and/or flavoring components, such as an essential oil. After mixing, additives such as fillers, pigments, and gelling agents are added. A solid plastic is producing by heating the formed plastisol to a gelation temperature and then heating to a solution temperature to generate a solid plastic with enduring bactericidal activity, scent, and/or flavor.

  • Patent number: 12281238
    Abstract: The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.
