Sol-gel coating formulations including metal oxide particles such as aluminum oxide, calcium oxide, zinc oxide, magnesium oxide, and molybdenum oxide embedded in a hybrid polymer matrix based on a reacted form of a resin composition containing a tetraalkylorthosilicate, an aminoalkylsilane, a dialkoxysilane, and a silanol terminated polydimethylsiloxane. The sol-gel coating formulations are suitable for applications such as anticorrosive protective coatings of metal substrates (e.g. mild steel). These anticorrosive coated metal substrates are evaluated on their hydrophobicity (water contact angle), surface roughness, mechanical strength (e.g. hardness), adhesiveness to the substrate (e.g. critical load), and anticorrosiveness upon exposure to a saline solution (e.g. impedance value).

A resin composition comprises a base resin containing an urethane (meth)acrylate oligomer, a monomer having a phenoxy group, and a photopolymerization initiator, and hydrophobic inorganic oxide particles, wherein the viscosity is 300 mPa.Math.s or more and 4200 mPa.Math.s or less at 45° C. and the content of the monomer having a phenoxy group is 1% by mass or more and 30% by mass or less based on the total amount of the base resin.

The invention relates to the field of road construction materials, and it is intended to improve the quality of road surfaces, roofing and insulating materials based on bitumens, which is achieved by improving the quality of bitumens with the help of using modified crumb rubber—a disposal product of used automotive and tractor tires, in particular, the invention relates to a low-temperature method for manufacturing modified crumb rubber to improve the quality of bitumens and asphalt concretes and to the technology for mixing it with bitumen, for the purpose of creating a uniform material that is not prone to destruction during long-term storage. The present invention consists in the development of a new method for manufacturing the modified crumb rubber, comprising preparing a mix from the following components: crumb rubber from used automotive and tractor tires with a particle size of up to 1 mm—50-65 wt. %, oxides and/or hydroxides of alkaline-earth metals—10-20 wt. %, petroleum oil of solvent refining with the viscosity of from 0.05 to 1.5 Pa*s at 60° C.—20-30 wt. %, an amine type antiageing agent—a heterocyclic nitrogen-containing compound—0.1-2.0 wt. %; mixing the components of the resulting mix with a shock-shear load on the material in a mixer-activator at a temperature of 80-120° C.; and further cooling the resulting mix to a room temperature.
