METHOD FOR TREATMENT OF WOOD MATERIALS |
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. |
