Special Issue Information

Dear Colleagues,

Silicone resins are tridimensional, highly branched polysiloxane made of different primary silicon units, namely the monofunctional unit (M), bifunctional unit (D), trifunctional unit (T) and tetrafunctional unit (Q). The highly branched polysiloxane chain structure gives them unique properties and allows their use in a variety of fields such as in aerospace (low- and high-temperature performance), electronics (as varnish in electrical insulations), cosmetic formulations (glossing or tackifying agents), masonry paints (as binders or water repellents), optical devices because of their light and heat stability (LED encapsulation), reinforcing agents in polymer compositions or pressure-sensitive adhesives (PSAs). In this Special Issue, we aim to highlight the most recent progress in the synthesis, characterization, modification and application of silicone resins and hope to provide new insights into their development. We invite original research articles and review papers that cover the emerging methods for synthesizing and characterizing silicone resins and new strategies in tailoring the chemical compositions, functionalities and performance in their applications.

As a bridge between the coating and the substrate, the primer has a direct impact on the adhesion performance of silicone resin thermal protection coating. In this paper, the synergistic effects of an aminosilane coupling agent on the adhesion performance of silane primer were investigated. The results show that silane primer containing N-aminoethyl-3-aminopropylmethyl-dimethoxysilane (HD-103) formed a continuous and uniform film on the surface of the substrate. Two amino groups of HD-103 were conducive to moderate and uniform hydrolysis of the silane primer system, and the introduction of dimethoxy groups was more conducive to the improvement of interfacial layer density and the formation of the planar surface structure, thus enhancing the bond strength at the interface. When the content was 13 wt%, it exhibited excellent synergistic effects on adhesive properties, and the adhesive strength reached 1.53 MPa. The possible morphology and composition of the silane primer layer were investigated by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). A thermogravimetric infrared spectrometer (TGA-IR) was used to analyze the thermal decomposition of the silane primer layer. The results showed that the alkoxy groups in the silane primer were first hydrolyzed to form Si-OH, and then the dehydration and condensation reactions between Si-OH and the substrate formed a firm network structure.
