| 摘要 |
The invention relates to an aldehyde based resin composition that has an ultralow formaldehyde (ULF) emission both on curing and from the final cured product and to the use thereof as a binder or adhesive for the manufacture of mineral wool (glass fibre and stone fibre) products, non-woven materials, wooden boards, plywood, coated materials and/or impregnated material products. The invention further relates to a process for the manufacture of the resin composition, to a sizing composition for use in mineral wool applications, to a sizing composition for use in saturation or impregnation applications, and to a curable aqueous composition for use in board and wood applications, comprising the aldehyde resin composition according to the invention. The aldehyde based resin composition, preferably formed by reaction of one or more hydroxy aromatic and/or one or more amino functional compounds (I) with one or more aldehyde functional compounds (II), contains one or more reducing sugars or a reducing sugar in the form of a carbohydrate feedstock with the bulk properties of a reducing sugar (III) with a dextrose equivalent (DE) value of at least 15, preferably at least 25, more preferably at least 50, even more preferably at least 75, and most preferably greater than 90, and optionally a cyanamide (IV). |
