摘要:
Use of a compound of formula (I) wherein R1 and R2 are selected independently from each other from C1-C10 alkyl, which may be substituted by one or more F, or wherein R1 and R2 are linked and jointly selected from C2-C3 alkanediyl forming together with the group -OPO- a five- or six-membered heterocycle which may be substituted by one or more substituents selected from F and optionally fluorinated C1-C10 alkyl, as gelling agent in an aprotic organic solvent or solvent mixture.

摘要:
Light, wood-containing material with an average density in the range of 200 to 600 kg/m3, containing, each referring to the wood-containing material: A) 30 to 95% by weight wood particles; B) 1 to 25% by weight a filler with a bulk density in the range of 10 to 150 kg/m3, selected from the group consisting of foamable plastic particles and plastic particles that are already foaming; C) 0.1 to 50% by weight a binder, and possibly D) additives, wherein component (B) contains foaming plastic particles gained by comminution from molds, in an amount, with reference to component (B), in the range of 1 to 100% by weight.
摘要:
The invention relates to a method for reducing the emission of formaldehyde in wood materials by applying nitrogen-containing compounds. Said method is characterized in that (i) a mixture containing at least one polyamine and optionally up to 20 percent by weight of urea relative to the mixture is applied to the wood material; (ii) polyamine is applied onto or into the chip cake or fiber cake; (iii) polyamine is applied to the coating substrate used for finishing the surface; and/or (iv) polyamine is applied to the exposed points. The polyamines have a minimum molecular weight of 500 g/mol while being provided with at least 6 primary or secondary amino groups.
