Dipping bath compositions for treating reinforcing inserts
The present invention relates to an aqueous, solids-containing dipping bath composition for treating reinforcing inserts for rubber products comprising the following components or consisting of these components, (A) at least one blocked MDI mixture, the MDI mixture comprising MDI oligomers of formula (I), n being a whole number from 1 to 8, and MDI monomers; (B) at least one resorcinol-formaldehyde latex; and (C) possibly at least one additive, wherein the dipping bath composition is essentially free of epoxides. ##STR00001##
Layered Material And Method For Producing A Layered Material
A method for producing a layered material, which has a substrate layer and a layer of polyurethane bonded to the substrate layer. A leather, preferably a sanded grain leather, a textile material, preferably a woven fabric or a knitted fabric, a bonded leather material, or a microfiber nonwoven is used as the substrate layer and is bonded to the layer. According to the present teaching, at least one, preferably a single, layer of frothed polyurethane foam is applied to the substrate as the layer.
Polyurethane-vinyl hybrid polymers, methods of making them and their use
Described are polyurethane-vinyl hybrid polymers, methods of making them and their use. The hybrid polymers are made from an anionic polyurethane and a polymerizable vinyl compound, wherein the polymerizable vinyl compound is selected from methylene malonates, methylene beta-ketoesters and methylene beta-diketones. The hybrid polymers can be used as binder in structural adhesives, as binder in pressure-sensitive adhesives, as binder in laminating adhesives, as binder in contact adhesives, as binder in ink, as binder in paints, as binder in coatings, as binder for fiber bonding, as binder for particle bonding or as binder in high cohesion adhesive tapes.
CARPET TILE
Mass production of carpet tiles can be enabled by a method for manufacturing a carpet tile by applying an adhesive layer to a carpet tile base material containing pile, the method including: a first process of mixing 15 to 25 wt. % of urethane resin glue to an acrylic foamed resin to produce 100 wt. % of a mixture, thereby obtaining an adhesive; a second process of subjecting the adhesive to viscosity adjustment to adjust viscosity thereof to 3000 to 6000 cps; and a third process of applying the adhesive to the carpet tile base material by using a screen mesh having a mesh thickness of 20 m or more and less than 100 m and an opening area ratio of 40% to 60%.
