“…Similarly, the wear resistance of the coating was reduced considerably for the samples that were painted out of the optimum temperature range. Some investigations have shown that the chemical reactions and interdiffusion of elements between the coating and substrate increase with temperature, which can improve the adhesion strength of the coating [44,45]. However, overheating can cause the opposite effect, reducing the adhesion due to a thermal degradation of the components of the coating [46].…”

One of the most important factors in the LPDC process is the heat transfer during the solidification of the molten alloys, which is responsible for the resulting microstructure and, thus, the quality of the cast piece. The use of foundry coatings has been lately suggested as a proper strategy to control the heat transfer while protecting bonded moulds from aluminium adhesion by providing a barrier between the surface and the liquid metal. LPDC die coating failures usually come from the loss of adherence or excessive wear originated in the successive filling processes, which requires stopping production for the reapplication of the coating. In the present work, coatings with different insulation capabilities have been evaluated, in terms of adherence and wear tests, in order to select the most promising alternative for LPDC die coating. This study confirmed that surface preparation and cleanliness are vital for an adequate adhesion of the coatings to ensure their durability. The results evinced that the use of a primer layer provided a higher adhesion of the coatings and considerably improved their perfomance. The coating that presented the best results in terms of adhesion and wear resistance under different abrasive testing conditions was coating B3.

“…Different processes like corona or plasma treatments on the substrates where silicone adhesives adhere to could be utilized to improve adhesion. − However, such methods may be impractical and tedious on a large-scale system. Another more practical way to enhance the adhesion of silicone adhesives is to incorporate adhesion promoters into the silicone adhesive formulation. − The commonly used promoters include organosilanes, titanates, and zirconates. , …”

Poly(dimethylsiloxane) (PDMS) has numerous excellent properties and is extensively used as the main component of many silicone products in a variety of research fields and practical applications such as biomedical materials, aviation, construction, electronic devices, and automobiles. Interfacial structures of PDMS and other components in silicone systems are important for such research and applications. It is difficult to probe interfacial molecular structures of buried solid−liquid and solid−solid interfaces of silicone materials due to the lack of appropriate analytical tools. In this feature article, we presented our research on elucidating the molecular structures of PDMS as well as other additives in silicone samples at buried interfaces in situ at the molecular level using a nonlinear optical spectroscopic technique, sum frequency generation (SFG) vibrational spectroscopy. SFG was applied to study various PDMS surfaces in liquid environments to understand their fouling-release and antifouling activities. SFG has also been used to study buried solid−solid interfaces between silicone adhesives and polymers, elucidating the molecular adhesion mechanisms. Our SFG studies provide important knowledge on interfacial structure−function relationships of silicone materials, helping the design and development of silicone materials with improved properties through optimization of silicone interfacial structures.
