An adhesive composition that is excellent in both adhesiveness and a holding force while having high flame retardancy. The adhesive composition contains an acrylic resin (A) containing a (meth)acrylic acid monomer (a1) unit and a hydroxyl group-containing monomer (a2) unit, an epoxy crosslinking agent (b1), an isocyanate crosslinking agent (b2), and a flame retardant (C).

The invention relates to a film comprising an interpenetrating network, its uses and processes for making the same. The film produced displays good durability, chemical resistance and transparency. The film is produced from an interpenetrating network formed as a colloidal suspension in an organic solvent and a particulate solid.

A two-component polyurethane coating composition is described. The composition includes a multifunctional isocyanate component and a multifunctional polyol component. The polyurethane described herein is an overindexed composition that may be used as a tiecoat in a conventional recoat or refinish process. The described composition provides improved adhesion between an aged coat and a newly applied coating.

The present invention provides a stabilising composition, comprising: a) a first phenolic antioxidant comprising one or more phenolic compounds having the structure of formula (I): ##STR00001##  wherein R.sub.1 is a linear or branched alkyl group having from 12 to 20 carbon atoms; and b) one or more second phenolic antioxidants independently selected from:  a mono-hydroxybenzene having lower steric hindrance than the first phenolic antioxidant;  a di-hydroxybenzene; and/or  a tri-hydroxybenzene.

A resin composition useful for additive manufacturing is provided, which resin composition may exhibit improved shelf life through inhibition of crystallization. Such resin composition may include a crystallization inhibitor as taught herein, and/or a prepolymer produced by reaction of an isocyanate with multiple isomers and comprising a lower percentage of the structurally symmetric isomer. Methods of forming a three-dimensional object using such resin composition are also provided.

A chemical composition for a degradable polymeric material includes an isocyanate terminated polyester prepolymer, including prepolymer units as a main chain with a plurality of isocyanates at ends of the main chain, and a cross-linking agent. The isocyanate terminated polyester prepolymer has a structural formula as follows: ONC—R″—NH—[—CO—R—R′″-]n-NH—R″—CNO, wherein R′″ is selected from a group consisting of —O— and —CO—O—R′—O—, ##STR00001##
wherein R, R′ and R″ are an aryl group or alkyl group and wherein n is a number of prepolymer units corresponding to length of the main chain. The composition degrades at a rate and at a delay depending on temperature and the composition for a component of a downhole tool. The composition has strength and elasticity for a component of a downhole tool.

The present invention relates to a thermoplastic molding compound comprising a polyalkylene terephthalate and a polyimide, wherein the molding compound has a single glass transition temperature in DSC measurement. The present invention further relates to the use thereof and to fibers, films and shaped bodies produced from the molding compound.

The present invention relates to a microballoon. The microballoon is made of polyurethane (urea). The microballoon is characterized in that an inner surface of the microballoon contains ionic groups. According to the present invention, through use for a CMP polishing pad, affinity with a slurry liquid for polishing is improved, and thus it is possible to provide a microballoon by which good polishing characteristics may be exhibited without lowering the resin strength of a polishing pad.
