  • HEAT-SEALABLE COATING SYSTEM SUITABLE FOR THE SEALING OF VARIOUS TYPES OF SUBSTRATES
    Publication number: 20260226307
    Abstract: The present invention is directed to a heat-sealable coating system suitable for the sealing of various types of substrates, comprising a film-forming dispersion, comprising a polyester or polyester mixture as polymer type A, a poly(meth)acrylate as polymer type B, a graft copolymer of polymer type A and polymer type B as polymer type AB, a polyolefin or a polyolefin mixture as polymer type C, and a graft copolymer as polymer type CD, composed of polymer type C and of a poly(meth)acrylate as polymer type D, wherein said dispersion comprises of from 30% to 60% by weight of ethyl acetate based on the total weight of the dispersion, and wherein said dispersion comprises of from 20% to 50% by weight of polymer type A, from 10% to 20% by weight by weight of polymer type B, from 10% to 20% by weight of polymer type AB, from 5% to 25% by weight by weight of polymer type C, and from 15 to 35% by weight by weight of polymer type CD, based in each case on the total mass of the polymer types A, B, C, AB, and CD, and to

  • AQUEOUS DISPERSION COMPRISING POLYMER PARTICLES USEFUL IN HEAT SEALING APPLICATIONS
    Publication number: 20240240065
    Abstract: The present invention is directed to an aqueous dispersion comprising particles comprising a first polymer phase and a second polymer phase, where the second polymer phase comprises from 2 to 10% by weight of units based on acids copolymerizable with methacrylates, based on the entirety of the two polymer phases, and wherein the particles have a particle size dso, determined as given in the description, of from 100 to 150 nm, and wherein the entirety of the polymers comprised in the particles comprise of from 49 to 65% by weight of units based on methyl methacrylate and/or butyl methacrylate, of from 22 to 33% by weight of units based on a C1-C4-alkyl ester of acrylic acid, of from 3 to 7% by weight of units based on a hydroxy-functional (meth)acrylate, of from 2 to 8% by weight of units based on (meth)acrylic acid, and of from 5 to 15% by weight of units based on styrene, based on the total weight of the polymers, to a process for preparing an aqueous dispersion comprising a first polymer phase and a second
