In order to develop polymeric composite materials (PCM) for coatings and sealants with good weather resistance and physical and mechanical properties, the object of research is oligomeric composition based on hydrogenated oligobutadienedions with finite hydroxyl groups. The main disadvantage of oligobutadienedion-based compositions is unsatisfactory chemical resistance to air, due to the presence of double bonds in the polymer chain. In order to maximize eliminate the main disadvantage, it is decided to use oligomers that are subjected to partial hydrogenation. It is revealed that GI oligomers can be considered as binding bases of mortarless elastomeric compositions for coatings and sealants with good weather resistance due to the low viscosity and sufficiently small unsaturation values. Analysis of the kaolin effect as a filler on structural and mechanical properties of GI oligomers is determines that due to the low structural viscosity of GI oligomers for practical use as a binding PCM bases, it is necessary further inject the structuring additives into them, for example – Aerosil. The presence of hydroxyl groups makes it possible to perform composition structuring using diisocyanates at room temperature to obtain ozone resistant sealants and protective coatings. It is determined that the coatings, derived from kaolin-filled (20 % wt.) and aerosil (5 % wt.) GI oligomer, are characterized by high adhesion to steel Ст3, more than 5 MPa for separation, without the use of primers and adhesives.
