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:
A low volatile organic compound (VOC) coating composition with a low viscosity is described. The coating composition includes a hydrocarbon solvent; a reactive or non-reactive diluent; a drier composition; and a hyper-branched alkylated polymer. A colorant can be added so that the coating composition can be used as a stain, such as a wood stain. The hyper-branched alkylated polymer functions as the main binder to provide an effective coating composition having a relatively low VOC level.
Abstract:
The present disclosure relates to a composition comprising: at least one dendritic polymer prepared from hyper-branched polymer with hydroxyl groups, having a plurality of peripheral functional groups, wherein the peripheral functional groups comprising at least one cyclic ether group that is covalently bound to said hyperbranched polymer by urethane linkages; and a melamine-based crosslinker. Such compositions have improved flexibility. The present disclosure further relates to the use of such compositions to form coatings after cure, or as an additive component to binder resins.
