Title
(EN) LOW FORMALDEHYDE EMITTING CROSS-LINKING AGENTS
(FR) AGENTS DE RETICULATION A FAIBLE EMISSION DE FORMALDEHYDE
Abstract
(EN)
Described is a liquid, partially alkoxymethylated melamine cross-linker composition having from about 2.6 to about 4.6 moles of combined formaldehyde per mole of melamine, from about 1.4 to about 4.4 moles of alkyl per mole of melamine, from about 1.3 to about 3.4 moles of NH per mole of melamine, a free formaldehyde level of less than about 0.5 weight percent based on 100 percent solids, and an N-methylol level of less than about 6.0 weight percent; processes for its preparation; a low formaldehyde emitting curable composition containing the cross-linker; as well as a method of coating a substrate and substrates so coated.
(FR)
L'invention se rapporte à une composition de réticulation liquide à base de mélamine partiellement alcoxyméthylée, contenant de 2,6 à 4,6 moles environ de formaldéhyde combiné par mole de mélamine, de 1,4 à 4,4 moles environ d'alkyle par mole de mélamine, de 1,3 à 3,4 moles environ de NH à moles de mélamine, un niveau de formaldéhylde libre inférieur à 0,5 environ, en poids, pour 100 % d'extraits secs, et un niveau de N-méthylol inférieur à 6,0 environ en poids. On décrit par ailleurs des procédés de fabrication de cette composition, une composition polymérisable à faible émission de formaldéhyde contenant l'agent de réticulation, et un procédé de revêtement d'un substrat ainsi que des substrats ainsi revêtus.
