摘要:
An object of the present invention is to provide a primer composition for application between the base film and the adhesive layer of an adhesive tape that can improve the adhesion between the base film and the adhesive layer of the adhesive tape and an adhesive tape prepared by using the primer composition. A primer composition, comprising 100 parts by mass (as solid matter) of a graft polymer of a natural rubber graft-polymerized with 15 to 65 mass % of methyl methacrylate and 25 to 300 parts by mass of a carboxyl group-modified acrylonitrile butadiene rubber.

Pigmented aqueous coating composition providing good blocking and elasticity properties comprises a blend of a seeded multistage polymer latex(es) having at least one soft and at least one hard polymer phases and a non-film-forming polymer latex(es), the seed polymer(s) having a Tg ≥ 10 °C lower than that of the hard polymer phase(s) and preferably having a Tg ≥ 10 °C higher than that of the soft polymer phase(s), and the multistage polymer(s) preferably having amino functionality incorporated by an imination reaction.
摘要:
Water redispersible powder of film-forming polymers that are water insoluble and prepared by polymerization in an aqueous emulsion of ethylenically unsaturated monomers with a core/shell structure including a hydrophobic core structure of a polymer having a Tg (glass transition temperature) of - 30 to + 25 DEG C, and preferably - 10 to + 20 DEG C and a hydrophilic shell of a polymer having a Tg above + 55 DEG C, and preferably above + 90 DEG C. The invention is characterized in that the shell is linked to the core by covalent bonds resulting from the reaction of a shell grafting agent on the ethylenic unsaturations remaining in the core, and is substantially insoluble in an alkaline medium.
摘要:
An aqueous, radiation-curable, functionalized latex polymer composition and its preparation are disclosed. The composition is a multistaged latex polymer formed from a first stage polymer and a second stage polymer having α, β-unsaturated carbonyl functionalization which permits curing by UV radiation. The composition dries tack-free before curing. The final cured UV coating has excellent solvent resistance, water resistance, stain resistance, direct impact resistance and hot print resistance. The composition is useful in coatings, adhesives, inks and leather coatings, and is particularly useful as a coating on wood.
摘要:
Die Erfindung betrifft neue Bindemittelkombinationen auf Basis von OH-funktionellen Pfropfcopolymerisatharzen und polyfunktionellen Vernetzungsmitteln, vorzugsweise organischen Polyisocyanaten und ihre Verwendung zur Herstellung von Überzügen auf Metall und Kunststoff. Die neuen Bindemittelkombinationen gestatten die Herstellung von Beschichtungen einer sehr guten Filmoptik und Chemikalienfestigkeit bei gleichzeitig hohem Elastizitätsniveau und sehr guter Oberflächenhärte der resultierenden Lackfilme.
