“…Desirable properties in waterborne coatings include flexibility [ 29 , 88 , 117 ], adhesion [ 81 , 118 , 119 ], wear resistance [ 92 , 102 , 120 , 121 , 122 ], and durability [ 120 ]. Among the possibilities for added coating functionality are, for example, flame retardancy [ 119 ], solvent and chemical resistance [ 123 , 124 ], stain resistance [ 102 , 124 ], anti-cavitation [ 81 ], extreme robustness (for space-based applications) [ 125 ], antimicrobial activity [ 126 , 127 , 128 , 129 , 130 , 131 ], superhydrophobicity [ 84 , 95 , 124 , 132 , 133 , 134 , 135 , 136 , 137 , 138 ], or photoactive fluorescent coatings [ 29 ] presented in Table 3 .…”

“…For example, SNPs increase the T g and hardness of polyurethane composite films, containing ethylene glycol methacrylate phosphate (EGMP), with the resulting material presenting also good adhesion to steel surfaces and flame retardancy [ 119 ]. In fact, silica-containing epoxy composites are already used in adhesives, paints, solvent and chemical resistance, and marine coating technology [ 118 , 123 , 130 ]. The use of 3-glycidyloxypropyl trimethoxysilane (GPTMS) and TEOS on epoxy composites lead to coating films with improved break resistance due to the hyperbranched structure of GPTMS, but also increased thermal stability and erosion resistance, for anti-cavitation coating applications [ 81 ].…”

Combining organic and inorganic components at a nanoscale is an effective way to obtain high performance coating materials with excellent chemical and physical properties. This review focuses on recent approaches to prepare hybrid nanostructured waterborne coating materials combining the mechanical properties and versatility of silica as the inorganic filler, with the flexural properties and ease of processing of the polymer matrix. We cover silica-polymer coupling agents used to link the organic and inorganic components, the formation of hybrid films from these silica-polymer nanostructures, and their different applications. These hybrid nanostructures can be used to prepare high performance functional coatings with different properties from optical transparency, to resistance to temperature, hydrophobicity, anti-corrosion, resistance to scratch, and antimicrobial activity.

A novel phosphorus‐based maleimide, tris[4‐(2,5‐dioxopyrrol‐1‐yl)phenyl] phosphite (TDPPI), was employed as a flame retardant in epoxy with moderate transparency, enhanced thermal stability, and improved mechanical strength. SEM studies ascertained the uniform dispersion of TDPPI and its compatibility with the epoxy. Differential scanning calorimetry showed that the epoxy compounded with 2.5 wt% of TDPPI achieved 100% curing with the glass transition temperature of 43.8°C. The thermogravimetric study revealed that the presence of 2.5 wt% of TDPPI in epoxy increased the residual mass found at 600°C by 23%. The epoxy thermoset compounded with 2.5 wt% of TDPPI passed the Underwriter's Laboratory (UL‐94) test with V‐1 classification and achieved the limiting oxygen index of 30.7% with a reduced burning rate of about 58.7%. At 1.5 wt% of the TDPPI, the resulting epoxy thermoset exhibited an enhancement in the tensile strength (23%), Young's modulus (37%), flexural strength (9%), and Izod impact strength (37%) relative to the neat epoxy. In conclusion, 2.5 wt% of TDPPI is adequate for imparting flame retardancy to epoxy composites with improved mechanical strength because of the maleimide‐phosphorus synergistic effect.Highlights TDPPI is a phosphorus and maleimide containing flame retardant. TDPPI improves thermal stability, flame retardancy and mechanical strengths. Only 2.5 wt% of TDPPI is required for epoxy to achieve high flame retardancy. Maleimide presence lowers phosphorus requirement for epoxy flame retardancy. TDPPI is a promising new flame retardant material for epoxy.

“…A common drawback of epoxy binders is a fairly rigid molecular structure that leads to an increase in viscosity, which complicates the application of coatings to the surface of the equipment. To solve this problem, various diluents are used in the form of solvents and plasticizers, which are introduced into the polymer matrix in a wide range of concentrations (Il'ina et al 2019). A negative effect of such operation is the impairment of physicalmechanical properties and significant shrinkage of PCM associated with loosening of the structure of the polymer binder (Brusentseva et al 2015;Buketov et al 2019;Geng et al 2016).…”

New Black-Filled Epoxy Coatings for Repairing Surface of Equipment of Marine Ships

The methods for ensuring long-term and safe operation of marine equipment due to comprehensive repair technologies that use epoxy oligomers and new compositions based on them are developed. The influence of temperature and UltraSonic Treatment (UST) on the rheological properties of the pure epoxy matrix and compositions based on it is explored. The compositions have different content of nanodispersed soot carbon black of brand PowCarbon 2419G (particle size of 24 ± 2 nm). It is established that when nanoparticle soot (q = 0.10…15.00 pts wt) is introduced into the composition of the epoxy matrix treated with ultrasound, the viscosity of the composition increases gradually. Based on the results obtained, temperature ranges are recommended, in which the viscosity of the studied compositions reaches optimal technological parameters for the effective impregnation of threads, tows and various fabrics, and which provide for the effective application of the composition to the working surfaces of marine equipment. Technical recommendations are given for applying the developed black-filled epoxy compositions to the working surfaces of parts, ship mechanisms and pipeline systems of marine vessels.
