摘要:
A method for making a polymeric part having an anti-graffiti property is disclosed. The method includes formulating a first mixture of a polymer and a hydrocarbon mixture, forming a substantially planar sheet of the first mixture, formulating a second mixture of a mineral oil and a wax, coating a surface of a forming mold with the second mixture of a mineral oil and a wax, and thermoforming the substantially planar sheet to form the polymeric part using the forming mold coated with the second mixture of mineral oil and wax.

Disclosed are compositions of ethylene acid copolymers and polyamides that are useful for fabricating films, sheets and molded articles for scuff and scratch resistant material and their application as decorative and protective films, comprising (1) from about 30 to about 65 weight % of a polyamide; and (2) from about 70 to about 35 weight % of a copolymer of (a) ethylene; (b) from about 5 weight % to about 15 weight % of an α,β-unsaturated C3-C8 carboxylic acid; (c) from about 0.5 weight % to about 12 weight % of at least one comonomer that is an ethylenically unsaturated dicarboxylic acid; and (d) from 0 weight % to about 30 weight % of monomers selected from alkyl acrylate and alkyl methacrylate, wherein the alkyl groups have from one to twelve carbon atoms; at least partially neutralized by one or more alkali metal, transition metal, or alkaline earth metal cations. Articles prepared from these compositions, such as films, show high toughness, good mechanical properties, excellent scratch and scuff resistance and, most importantly, good optical properties. More particularly, the compositions of ethylene copolymers and polyamides of the present invention can be used as protective coatings or layers on scuff- and scratch-exposed objects.
摘要:
Protective shields configured to prevent projection against projectiles, such as during excavating and/or mining operations, are provided. The protective shields include a base layer comprising one or more transparent polycarbonate layers, a sacrificial polycarbonate layer comprising a transparent polycarbonate, and an air gap positioned directly between at least a portion of the base layer and the sacrificial polycarbonate layer. The sacrificial polycarbonate layer is directly or indirectly attached to the base layer in a manner to provide the air gap positioned between the base layer and the sacrificial polycarbonate layer.

摘要:
An aspect of the invention relates to a surface cover for a body which can be brought into contact with a liquid, comprising: a layer which at least partly contains gas and which is designed and arranged such that at least some sections of a layer face facing the liquid contacts the liquid; a gas-permeable layer which is arranged on the gas-containing layer on a face that faces the body and is opposite the face facing the liquid or which is integrally formed with the gas-containing layer; and a gas-supplying device which is connected to the gas-permeable layer such that gas can flow from the gas-supplying device to the gas-containing layer through the gas-permeable layer. The invention also relates to an arrangement and a use.
摘要:
There are provided a pressure-sensitive or bonding adhesive layer that, when a repairing or reinforcing sheet is laminated onto concrete, can temporarily fix the sheet to the concrete to facilitate the repair or reinforcement of the concrete, and a pressure-sensitive or bonding adhesive sheet that includes the pressure-sensitive or bonding adhesive layer. The pressure-sensitive or bonding adhesive layer contains an acrylic resin having a glass transition temperature of 15° C. or below and further contains a liquid epoxy resin, a solid epoxy resin, and a curing agent. A pressure-sensitive or bonding adhesive sheet includes a pressure-sensitive or bonding adhesive layer and a separation film or a repairing or reinforcing sheet provided on one surface of the pressure-sensitive or bonding adhesive layer.
摘要:
A compact laminated assembly based upon a saturation grade paper made using a grass fiber or grass/wood fiber blend, instead of the conventional wood fibers from trees. A plurality of the grass paper sheets are substantially impregnated using a thermosetting resin and stacked in a superimposed relationship. The assembled stack of resin impregnated paper sheets are heat and pressure consolidated into a substantially homogenous monolithic mass with the thermosetting resin being substantially completely cured. A film of a substantially completely cured solid powder coating composition is laminated to at least a portion of an outer surface of the compact laminated assembly.

Manufacturing methods and systems providing continuous rolls of polyvinyl materials printable on one side and “sticky”-adherable on the other side. Such continuous rolls may be thereafter cut into sizes appropriate for signs, bumper stickers, and other information and/or design objects which are affixable to appropriate surfaces for a variety of advertising and/or design uses.
摘要:
The present invention relates to a decorative panel comprising a decorative layer on one or both surfaces of a carrier layer. In addition to that, the present invention relates to a method for manufacturing a decorative panel consisting of a carrier layer and a decorative layer. The invention also relates to a method for forming a decorative layer.
摘要:
A film is described comprising a first film layer having a Tg ranging from 30° C. to 60° C. The first film layer comprises a (meth)acrylic polymer and polyvinyl acetal polymer composition. The film further comprises a second layer proximate the first film layer. The second layer is different than the first film layer. The second may be a cured (meth)acrylic polymer film or coating; a backing such as thermoplastic polymer, woven or nonwoven fabrics, metal foils, paper, foams; or a coverfilm such as a fluoropolymer.
