Abstract
A high gloss laminated panel is manufactured by applying a layer of a resin composition on a substrate layer and applying elevated pressure at elevated temperature for a time sufficient to at least partially cure the resin preferably without back-cooling. The resin composition includes a melamine formaldehyde resin in water and further includes one or more additives chosen from the group of thiourea, 1-amino-2-thiourea, stabilized guanidine, thio-acetamide, or an additive.
Claims16
A process for the manufacture of a high gloss laminated panel comprising the steps of applying a layer of a resin composition on a substrate layer and applying elevated pressure between 15 and 50 bar at elevated temperature between 130 and 220° C. for a pressing time between 7 and 60 seconds to at least partially cure the resin composition without back-cooling wherein the resin composition comprises a melamine formaldehyde resin in water and further comprises one or more additives chosen from the group of thiourea, 1-amino-2-thiourea, stabilized guanidine, thio-acetamide, or an additive according to formula 1:
- wherein R1 and R4 are an alcohol, and R2 and R3 are a polyol.
