Abstract (en)
[origin: WO2018085188A1] The invention relates to an unsaturated polyester resin of low molecular weight which is useful for the preparation of engineered stone. When mixing the unsaturated polyester resin with a fine inorganic particulate material such as cristobalite, a formable composition is obtained that can be further processed and cured to finally yield engineered stone as composite material. The invention also relates to a method for the preparation of engineered stone as well as to the use of the unsaturated polyester resin for the preparation of engineered stone.
