Abstract:
A hydrophilic, substantially epoxy-free self-cross-linkable polymer contains hydroxyalkyl carbamate groups and one or more tertiary amine groups. The polymer suitably is made by reacting an epoxy resin having an average epoxy equivalent weight of from about 100 to about 700 with one or more amines having at least one secondary amine group and at least one hydroxyalkyl carbamate group or precursor thereof. A coating composition comprises an aqueous medium containing the polymer and, optionally, a cross-linking catalyst. A low temperature-curable coating is attained by utilization of the polymer with a suitable quaternary or ternary compound catalyst.
Abstract:
A method of manufacturing a mineral fibre thermal insulation product comprises the sequential steps of:
Forming mineral fibres from a molten mineral mixture; Spraying a substantially formaldehyde free binder solution on to the mineral fibres, the binder solution comprising: a reducing sugar, an acid precursor derivable from an inorganic salt and a source of nitrogen; Collecting the mineral fibres to which the binder solution has been applied to form a batt of mineral fibres; and Curing the batt comprising the mineral fibres and the binder which is in contact with the mineral fibres by passing the batt through a curing oven so as to provide a batt of mineral fibres held together by a substantially water insoluble cured binder.
Abstract:
The present invention provides a coating composition which cures at low temperatures to form a cured film having high solvent resistance. The present invention provides a low-temperature-curable coating composition which comprises (A) a film-forming polymer having a hydrogen-donating functional group that has a heteroatom which bonds covalently to a hydrogen atom, (B) a film-forming polymer having a specific hydrogen-accepting functional group that has a heteroatom to which no hydrogen atom bonds covalently, and (C) a non-basic volatile solvent selected from the group consisting of a non-basic volatile solvent (C-1) having, in the molecule, both a heteroatom that bonds covalently to a hydrogen atom and a heteroatom that does not bond covalently to a hydrogen atom; a mixture of a non-basic volatile solvent (C-2) having, in the molecule, a heteroatom which bonds covalently to a hydrogen atom and a non-basic volatile solvent (C-3) having, in the molecule, a heteroatom to which no hydrogen atom bonds covalently; and combinations thereof.

An un-reacted substantially formaldehyde free curable binder solution for binding loose matter consists essentially of a solution obtainable by dissolving a reducing sugar, an ammonium salt acid precursor, optionally a carboxylic acid or a precursor thereof and optionally ammonia in water.
Abstract:
An anchor layer formation composition, a pressure-sensitive adhesive layer-attached optical film, and an image display device are provided, in which the composition includes an oxazoline group-containing polymer and an ionic compound including a cation component and a sulfonyl group-containing anion component and is capable of forming an anchor layer that can improve the adhesion between a pressure-sensitive adhesive layer and an optical film when interposed therebetween, the pressure-sensitive adhesive layer-attached optical film has high durability and good reworkability and allows the pressure-sensitive adhesive layer to resist chipping, and the image display device has the pressure-sensitive adhesive layer-attached optical film.
Abstract:
Methods and compositions related to chemically active hexahydrotriazine inorganic-organic hybrid coatings are described. The coatings have affinity for sulfur compounds, and thus may bind or capture sulfur containing contaminants and gases. The coatings have organosilicon containing functional groups and segments, and may also contain silica particles, which cumulatively enhances adhesion, abrasion resistance and further provides steric barriers to gaseous diffusion. The coatings have utility as protective barrier coatings in the field of electronics.
Abstract:
Crosslinkable reactive polymers comprise -A- and —B— recurring units, arranged randomly along a backbone. The -A- recurring units comprise pendant aromatic sulfonic acid oxime ester groups that are capable of providing pendant aromatic sulfonic acid groups upon irradiation with radiation having a λmax of at least 150 nm and up to and including 450 nm. The -A- recurring units are present in the reactive polymer in an amount of greater than 50 mol % and up to and including 98 mol % based on total reactive polymer recurring units. The —B— recurring units comprise pendant groups that provide crosslinking upon generation of the aromatic sulfonic acid groups in the -A- recurring units. The —B— recurring units are present in an amount of at least 2 mol %, based on total reactive polymer recurring units. These reactive polymers can be used in various pattern-forming methods.
