Abstract— Fracture behaviour of injection-moulded polypropylene filled with silane-treated talc was studied as a function of filler volume fraction (0–20%) and compared to that of polypropylene filled with untreated talc. High-rate tests (0.57 m/s) on SENB specimens were carried out using an instrumented Charpy impact pendulum, and linear elastic …
Les agents d'imprégnation hydrofuge sont généralement à base de silane, siloxane ou un mélange de ses matériaux. Les agents d'imprégnations sont un hydrofuge invisible appliqué sur le béton, la brique ou autre surface de maçonnerie ; il pénètre ensuite dans les pores et les capillaires où il peut augmenter la durabilité de la structure.

Los mayores valores de adhesión se alcanzan cuando al grabado con ácido fluorhídrico le sigue la aplicación de Silane. Los estudios han demostrado que Silane, en combinación con Porcelain Etch y PQ1 o con PermaQuick Bonding Resin, ofrece la mayor fuerza adhesiva en comparación con otros productos de adhesión para porcelana.
The content of maleic anhydride grafted polypropylene (MA-g-PP) was varied between 1 and 5 wt% in polypropylene/talc composites. The surface modification of talc powders has a significant effect on the interfacial structure and the mechanical properties such as tensile strength and impact strength of polypropylene/talc composites.

It is also a forum where people with an interest in talc can find information and support, and exchange views. The association has an established tradition of research and information in its main areas of interest:
Triethoxycaprylylsilane (TC)-Treated Pigments; INCI name: Triethoxycaprylylsilane. Triethoxycaprylylsilane, C8 (TC)-treated pigments and fillers are coated with an alkyl silane which provides a very hydrophobic coating that increases the ease of particle dispersion in natural and synthetic fluids and helps to stabilize particles in emulsion systems.
Addition of silane treated talc improved the mechanical properties as compared to TPU/PP/talc blends without chemical modification of talc. The results of strength correlate to the values of the storage modulus and crystallinity of the investigated TPU/PP/talc blends. ... [12] J. I. Velasco, J. A. De Saja and A. B. Martinez: J. Appl.

The mineral talc is an example of a phyllosilicate complex. Tectosilicates. ... The largest silane has a maximum of six silicon atoms (see Figure 11). Figure 11: The largest silane, hexasilane. Hexasilane is the largest possible silane because Si-Si bonds are not particularly strong. In fact, silanes are rather prone to decomposition.
