Mechanical behaviour of coating films

Viscoelastic and thermal properties of linseed oil-based ceramer coatings

“…It has been speculated that the large increase in crosslink density with increasing sol-gel precursor content may be due to the inorganic particles within the organic phase. In pigmented coatings, an increase in pigment volume concentration (PVC) will generally increase the modulus 15) . This phenomena is more pronounced for films containing small pigments and has been postulated to be due to the adsorption of polymer chains on pigment particles reducing the averaging chain length.…”

Effect of the addition mode of cycloaliphatic diepoxide on the morphology and film properties of crosslinkable core‐shell latex

“…As a result, intraparticle crosslinking was expected to make a smaller contribution to the build‐up of crosslink density of LA films, and accordingly, the films based on LAE exhibited slightly lower crosslink densities. Intraparticle crosslinking, especially before LA coalescence, will inhibit or retard the interdiffusion, lowering the surface sensitive properties, such as hardness 45–47. The LA film prepared from LAE combined intraparticle and interparticle crosslinking, but in the LA film based on LA without expoxide, intraparticle crosslinking was expected to be less significant.…”

Epoxidized soybean oil‐based ceramer coatings

“…The difference in hardness data is not surprising. Typically, the Tukon hardness is correlated to the modulus and less sensitive for elastic films, whereas the pencil hardness normally is related to strain-at-break (14,15). Tensile properties.…”
