摘要:
The invention relates to a substrate intended in use to contact a fouling agent, the substrate including a coating comprising polysaccharide, which coating serves to reduce or prevent fouling of the substrate caused by contact from the fouling agent, in comparison to an equivalent uncoated substrate. The invention also relates to the anti-fouling coating, to apparatus comprising such coating and to related methods of reducing or preventing fouling of a substrate intended in use to contact a fouling agent.
摘要:
A barrier packaging material containing a composite which comprises i) a cellulosic layer; ii) at least one metal layer which will dissolve under alkaline conditions; and iii) at least one polymer layer, in which the polymer is hydrolysable under alkaline conditions. The invention also relates to articles comprising the barrier packaging material. Further, the invention concerns the use of a polymer, which is hydrolysable under alkaline conditions, as a protective layer in barrier packaging products. In addition the present application is also concerned with a method for recycling the aforementioned barrier packaging products. Specifically the barrier packaging products are initially taken in an aqueous wastepaper suspension which is either pulped in an alkaline medium and/or treated in an alkaline medium in a deinking process and in which the metal and polymer are then separated from the cellulosic fibres contained in the cellulosic layer.
摘要:
The invention provides a novel flexible, substantially gas impermeable laminate material comprising starch/polymer blends, which can be used to make dispensing tubes, e.g., for toothpaste, which material is light, resilient, and inexpensive, which can be made almost entirely from renewable materials, and which can be recycled.
摘要:
The invention provides protein adhesives and methods of making and using such adhesives. The protein adhesives contain ground plant meal or an isolated polypeptide composition obtained from plant biomass.
摘要:
Provided is a flame-retardant member having flexibility and a high degree of flame retardancy. A flame-retardant polymer member of the present invention is a flame-retardant polymer member having a polymer layer (B) and a flame-retardant layer (A) on at least one surface of the polymer layer (B), in which the flame-retardant layer (A) is a layer containing a layered inorganic compound (f) in a polymer (X) .
摘要:
The invention relates to a multilayer printable sheet (10), including a bottom support layer (12), an intermediate metal layer (14) and a top layer (16) made of transparent or translucent plastic material, a top surface of said layer of plastic material being covered with a coating layer (18) made of a transparent or translucent matte varnish with a soft or silky touch.
摘要:
The invention relates to moisture-curing compositions which comprise at least one silane-functional polymer P with at least two terminal groups of formula (I), at least one aminosilane AS and at least one (meth)acrylsilane or anhydridosilane of formula (II). The compositions have improved adhesive properties and are especially suitable fur use as adhesives, sealing materials or coatings, especially as elastic adhesive or sealing materials.
摘要:
The invention concerns a lubricating metal coating, and a method for making same. The material constituting the coating is a composite material comprising a metal matrix wherein are distributed sheet talc particles, the metal matrix consisting of a metal selected among Fe, Co, Ni, Mn, Cr, Cu, W, Mo, Zn, Au, Ag, Pb, Sn or of an alloy of said metals, or of a metal-metalloid alloy. The coating is obtained by a method which consists in carrying out an electrodeposit using a solution of precursors of the metal matrix of the coating containing additionally suspended talc particles surface-modified by irreversible adsorption of a cellulose-derived compound by substituting all or part of the hydroxyl groups.
摘要:
Carboxyalkylcellulose esters are disclosed having relatively low degrees of polymerization. These new carboxyalkylcelIulose esters include carboxymethylcellulose acetate, carboxymethylcellu lose acetate propionate, and carboxymethylcellulose acetate butyrate. The inventive esters exhibit solubility in a range of organic solvents, and are useful in coatings and ink compositions as binder resins and rheology modifiers.
