Summary:For the production of sandwich structure elements comprising noncellular polyurethane layers and polyurethane foamed layers which are produced on a substrate by the application of layers to a substrate, it is proposed that at least the non-cellular polyurethane layers contain 15 to 55 % by weight of mica. Sandwich structure elements are obtained which are particularly dimensionally accurate and which adhere well. The effect is believed to be based on a non-homogeneous curing reaction of the mixture which reacts to form polyurethane, due to the presence of mica.
