- ABSTRACT: The purpose of this work is to develop compositions based on different types of HUPER with the addition of specific amounts of water that do not hinder the cross-linking of the unsaturated polyester. Hydrophilized unsaturated polyester resin (HUPER) diluted with specific amounts of water are presented. The unsaturated polyester resin (UPER) is modified with different reagents (cement, water glass, sodium hydroxide, sulfur) after which the addition of water is completely possible in technical terms. Water-diluted HUPER acquires new specific properties – visually it is more homogeneous, in certain cases it is gypseous, highly embossed and with relatively good strength indicators. The aqueous compositions of combined hydrophilizing agent of 13% SC/ 3.5% WG and 12% SC/7% WG demonstrate increased tensile strength by 50 to 70% and tensile elongation by 90 to 130%. Composites based on NaOH with small amounts of water (up to 15%) show increased tensile strength by up to 47% and increased tensile elongation by up to 100%.
