摘要:
A nanometal ink capable of forming a metal film that exhibits good adhesion to a substrate and has low resistance. The nanometal ink is a baking-type nanometal ink, and contains metal nanoparticles, a polymerizable compound, a polymerization reaction initiator, a volatile liquid medium, and a dispersant. The polymerization reaction initiator is to be activated by the action of heat and/or light, to allow polymerization of the polymerizable compound to proceed. The dispersant includes a C 6-14 alkylamine.

The present invention pertains to the uses of HiOmega flax (linseed) oil, a naturally occurring flax (linseed) with higher than normal alpha linolenic acid content in the production of stronger, more scratch and solvent resistant industrial products such as alkyd resins, epoxidized oils, epoxies, inks, coatings such as paints, enamels, varnishes and films and anti-spalling concrete preservatives.
摘要:
The invention relates to a preservation/lubricant/primer-composition for metallic substrates, in particular for steel substrates such as strip steel, comprising at least one epoxidized oil. The composition can further contain at least one cross-linking component, such as an UV-initiator or a fatty polyacid. The epoxidized oil is preferably an epoxidized derivative of a natural unsaturated fat or oil, in particular an epoxidized derivative of a natural "drying oil". The composition can be used as a preservative, a lubricant and/or a primer for metallic substrates, in particular for storage/transportation, forming/(draw)processing, and/or applying a coating. The invention circumvents the use of separate compositions for each of these processing steps.

Another resin composition for coating which contains an epoxidized block copolymer (A), an organic compound (B) carrying a functional group reacting with an epoxy group and having a number-average molecular weight of from 150 to 150,000, and an epoxy ring opening promoter (C), wherein the weight ratio (A)/(A + B) ranges from 1/100 to 99/100 and the content of the above component (C) ranges from 0.1 to 10 parts by weight per 100 parts by weight of (A + B).
摘要:
A powder coating composition and method of applying it to a substrate, such as medium density fibreboard, consisting of a glycidyl methacrylate resin, a dicarboxylic acid cross-linking agent, a catalyst selected from phosphines, phosphonium, ammonium 2-phenyl-2-imidazoline, substituted imidazoline and isopropyl imidazole Bis-A epoxy resin adduct and a matte texturing agent. The inventive formulation is able to create a matte texture finish on the surface of the substrate. Since the cured final coating is resistant to yellowing and moisture, it is of great utility in the kitchen cabinet making industry.
摘要:
A flat structure has at least one support layer (I) and at least one transparent coating layer (II), an optional backing layer (III) made of a chemically or mechanically foamed material arranged under the support layer (I), and an optional compact or priming layer (IV) arranged between the support layer (I) and the coating layer (II) and/or between the support layer (I) and the backing layer (III). The coating material for layers (II), (III) and (IV) is made of a combination of (a) epoxidation products of unsaturated fatty acid esters having a chain 8 to 22 carbons long with polyvalent aliphatic alcohols with 2 to 6 C atoms and in average more than one epoxide group per molecule; and (b) partial esters of polycarboxylic acids with polyether polyols containing at least one free carboxylic acid group per molecule and a double bond; (c) an optional water-proofing agent; and (d) other optional additives from the group that consists of fillers, pigments, foaming agents and auxiliary substances. The weight ratio between components (a) and (b) lies between 0.6:1 and 1:1.4.
摘要:
A mixture comprising epoxidized liquid rubbers, amine hardeners and sulfur applied to a metal and cured produces a coating that is highly durable and provides strong anticorrosive protection to the metal. The amine hardeners (16) serve to activate and dissolve the sulfur, speed up the curing time, and also to link the rubbers (10) to each other, creating a continuous molecular matrix (22). The activated sulfur (12, 20) also links the rubber molecules together, as well as anchoring the polymer matrix (22) to the metal substrate (18) via chemical bonds. In a preferred embodiment, the formulation also includes two types of accelerators which act synergistically to further reduce the curing time to less than one hour. The addition of micronized aluminum oxides provides increased uniformity of heating during curing and results in a more uniform coating. The addition of calcium oxide together with the presence of amines and aluminum oxide provides a complete absorption of acidic gases produced during curing. The addition of high molecular butadiene nitrile rubber increases the coatings impact resistance, low-temperature flexibility, and adhesion.

摘要:
Coating compositions are disclosed having a non-bisphenol A based film forming resin and an adhesion promoter resin. The coating compositions provide an alternate to epoxy resins that still allow melamine formaldehyde free cure, blush resistance, capability to retort and can withstand hard-to-hold beverages. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Substrates can be coated by preparing an adhesion promoter composition by a method including mixing an epoxidized resin and a solvent to form a mixture, adding a phosphoric acid compound to the resulting mixture to form a phosphate ester, adding water to partially hydrolyze the phosphate ester, and adding a neutralizer to form the adhesion promoter resin, followed by blending the adhesion promoter resin with a non-bisphenol A based film forming resin to form a coating composition, and applying the coating composition to the substrate.
