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:
An object of the present invention is to provide a coating composition that has excellent storage stability, achieves water and oil repellency over a long period of time, and has excellent chemical resistance and processability. To achieve this object, the present invention provides a copolymer resin (A) comprising, as constituent components, a polybasic acid component (a1); a compound (a2) containing at least one member selected from a secondary-hydroxyl-group-containing polyhydric alcohol component (a21) and a compound (a22), which generates one or more secondary hydroxyl groups by reaction with one or more carboxyl groups; and a specific fluorine-containing diol (f), the component (f) being used in a proportion of 0.1 to 30 mass %, based on the total mass of the constituent components.
