Abstract The special performance properties noted for silane coupling agents in mineral filled EPDM compounds result from the interfacial effects related to the dual function reaction of the organofunctional silane. When common alkoxy substituted vinyl silanes are used, the nature of the hydrolyzable groups on the silicon atom is generally not a critical factor with adequate silane-filler bonding occurring under a variety of silane application techniques. It has been shown that to obtain optimum performance, the organofunctional group in the silane monomer must be generally reactive with the cure system being used, and have the ability to interact with the elastomer through co-polymerization or addition. It has been further shown that in the case of the copolymerizable vinyl silane (A-172) only a relatively low level of peroxide-induced vinyl silane-rubber bonding is obtained using standard levels of peroxide. Increasing the peroxide level in these vinyl silane-containing formulations results in a considerably higher level of filler-elastomer reinforcement producing dramatic improvements in modulus, tensile, and tear properties when compared with appropriate controls. In general, an enhanced utilization of silane at the elastomer-filler interface is realized. The use of the mercaptosilane (A-189) in sulfur curing mineral filled EPDM compounds improves the normal physical properties while dynamic testing also shows improvements in flex-life, abrasion, heat build-up, and road wear properties.

Coating Formulation

In this study, the coating order of two monomers in the shell polymerization process of core-shell nanoparticles was altered to facilitate easy coating and optimize the properties of the coated surface to simplify the additional coating formulation process. To obtain a glass transition temperature suitable for coating, a core was synthesized by the copolymerization of an acryl monomer. A perfluoro monomer and silane monomer were additionally added to synthesize nanoparticles exhibiting both water–oil repellency and anchoring properties. In order to realize various surface properties, the nanoparticles underwent surface modification and cellulose fiber was introduced. Through the various data described in this text, the surface properties improved with the order of the introduction of the two monomers.

In this study, octyl-triethoxysilane emulsion was prepared using octyl-triethoxysilane monomer. The protective effect of the silane monomer and emulsion was investigated on the concrete with different water to cement ratios (0.4 and 0.5). The results showed that octyl-triethoxysilane emulsion displayed efficient protection of concrete. Octyl-triethoxysilane emulsion acquired excellent penetration depth (> 3.7 mm), the water absorption coefficient was reduced by 83.4%, and the chloride ion diffusion coefficient was only 1.8 × 10−12 m2 s−1, reduced by 71.3%. The emulsion also showed good resistance to carbonization and freezing-thawing. The carbonation depth of concrete was reduced by 42%, while the silane monomer has little effect on carbonization. Good protection performance was obtained in the freezing-thawing cycle tests. The relative dynamic elastic modulus was increased by 27%; the mass loss was reduced by 49% after 300 cycles. The protective effect of silane emulsion was also related with the water cement ratio of concrete and the test method. Silane monomer had good waterproof effect and chloride resistance, but poor resistance to carbonization and freezing-thawing. Silane emulsion was a better choice for concrete protection, for it displayed lower rate of volatilization, insignificant toxicity, and better retainment of the active ingredient.

In this communication, a bis-silane prepolymer was used to modify epoxy resin, aiming to enhance the corrosion resistance of epoxy coatings on aluminum alloy substrates. The bis-silane prepolymer was prepared by tetraethoxysilane (TEOS) and γ-glycidoxypropyl trimethoxysilane (GPTMS). The corrosion behavior of silane-epoxy coatings was studied. Compared with silane monomer-modified epoxy coatings, bis-silane-modified epoxy coatings have lower coating capacitance (Cc), higher charge transfer resistances (Rdl), and lower double layer capacitance (Cdl) during long-time immersion. It indicates that bis-silane-modified epoxy coating has stronger waterproof permeability and substrate corrosion protection ability. In addition, due to the leaching of the silane component and cross-linking reaction between different silanes during the immersion process, the bis-silane-modified epoxy coatings exhibit much stronger “self-healing” ability.
