  • Publication number: 20230114977
    Abstract: Disclosed are silane functionalized rosins having multiple functionalities. Such silane functionalized rosins are curable and thus capable of providing unexpected properties for various uses and end products. Also disclosed are synthetic routes to prepare silane functionalized rosins, which are formulated with hydroxyl functional polymers to provide curable adhesive compositions. The adhesives may be used for woodworking, automotive, textile, appliances, electronics, bookbinding, and packaging. Suitable substrates can be metal, polymer film, plastics, wood, glass, ceramic, paper, and concrete.

  • Publication number: 20070137821
    Abstract: Processes for rendering a polyamine-epihalohydrin resin storage stable, including processes that prepare a storage stable resin and/or processes that treat resins. A composition containing a polyamine-epihalohydrin resin which includes CPD-forming species can be treated with at least one agent under conditions to at least one of inhibit, reduce and remove the CPD-forming species to obtain a reduced CPD-forming resin so that a composition containing the reduced CPD-forming polyamine-epihalohydrin resin when stored for 2 weeks at 50° C., and a pH of about 2.5 to 3.5 contains less than about 250 ppm dry basis of CPD. The invention is also directed to a gelation storage stable reduced CPD-forming resin so that a composition containing the reduced CPD-forming polyamine-epihalohydrin resin, when stored at pH 1 for 24 hours at 50° C. and measured at 24 hours, produces less than about 1000 ppm dry basis of CPD.

  • Publication number: 20070135542
    Abstract: Anionic emulsifiers based on rosin acid or derivatives thereof, and to methods of preparing said emulsifiers. The emulsifiers are useful for preparing tackifier dispersions having improved properties with respect to foam stability. As such, said tackifier dispersions are advantageously used in water-based adhesives providing improved adhesive and cohesive properties. The adhesives may be used for labels on any kind of surface, packaging applications, flooring adhesives, road markings or for any type of water-based tapes, barrier coatings or sealants.
