Hydrophobization of Silicon Dioxide Microspheres With Resin Acids of Natural Gums

Currently, hydrophobic materials and coatings are of great practical interest due to their unique functional characteristics. The aim of this study was to develop a hydrophobic agent based on SiO2 microspheres hydrophobized with resin acids of natural gums to protect various surfaces. According to q...
