Abstract:
The invention relates to an aminoplast resin nonwoven film containing a nonwoven that is impregnated with a cross-linkable aminoplastic resin, the nonwoven containing 1 to 100 % by weight of melamine fibers with regard to the total fiber content. The invention also relates to the use of aminoplast resin nonwoven films for 3D coating substrates with a three-dimensionally structured surface. The invention further relates to laminates containing a substrate, optionally a woven or decorative paper and to the aminoplast resin nonwoven film according to the invention.
Abstract:
The invention relates to aminoplastic resin films containing decorative paper impregnated with a homogeneous, single-phase aminoplastic resin mixture containing (A) between 50 and 99.9 wt. %, in relation to the aminoplastic resin mixture, of aqueous condensation products containing 1 mol melamine and between 1.3 and 2.5 mol formaldehyde, (B) between 0.1 and 30 wt. %, in relation to the aminoplastic resin mixture, of specific polyalkylene glycols and/or polyalkylene glycol derivatives, and (C) between 0 and 20 wt. %, in relation to the aminoplastic resin mixture, of additives, auxiliary agents and/or additives. The invention also relates to the use of said films for coating derived timber products or plastics, especially for coating three-dimensionally structured surfaces. The invention further relates to the use of specific polyalkylene glycols, polyalkylene glycol derivatives and/or alkoxylated polyamides as bonding agents for plastic surfaces in aminoplastic resins, and also to specific aminoplastic resin mixtures.
Abstract:
The process applies components in the form of lines or dots, whereby the number and position of lines or dots can be altered. The installation to carry out this process includes a conveying device (3) for the substrate and at least one coating portal to which are attached supply leads for the components. The coating portal has an application device for each component and the application device has closable nozzles (4) , which can be opened and closed through rotation using a rotary valve nozzle system (5) .
Abstract:
The invention relates to a method for producing coated substrates comprising a three-dimensionally structured surface. According to said method, a decorati ve paper containing between 5 and 90 wt. % synthetic polymer fibres, in relatio n to the total fibre content, is impregnated with a cross-linkable amino resin , is applied to the substrate and three-dimensionally shaped. The invention al so relates to amino resin sheets or films and to the use of a modified decorati ve paper for amino resin sheets or films for the 3D coating.
