Among the key trends identified in this report are: improving the heat and chemical resistance of high perfomiance elastomers to allow their use in more demanding under-the-hood applications in automotive and engine construction; developing low cost high performance elastomers with better heat resistance performance to use in multiple applications in automotive construction; leveraging new market opportunities for elastomer components in autonomous vehicles and in the battery systems of the next generation electric vehicles; boosting silicone elastomers' heat resistance to over 300[degrees]C through the wider use of specialty polysiloxane additives; and potential new markets in cabling are waiting if high performance elastomers can be engineered with better water resistance.

AkzoNobel is deploying its Interzinc 52 primer; the Intergard 475HS, a high build epoxy providing protection against corrosion; Interthane 990, a high-build epoxy finish coating and Interfine 979 polysiloxane topcoat system for Ain Dubai.
He added, "Our Linesoft WSC-40 is a new ternary block silicone for cotton, which is a three-component block copolymer of polysiloxane, polyamines and polyether."
Furthermore, deployment of polysiloxane coatings on vessel surface makes the surface durable and resistant to abrasion, wear, and weathering, leading to market growth.
Given the importance of the aforementioned approaches in the case of multicomponent nanofunctionalization, here, the Ti[O.sub.2]-containing nanolayered silicate, montmorillonite (Mt), as an isotropic/anisotropic mixed nanocolloid, has been used to achieve multiple-size nanoroughness, as well as multifunctional properties via ultrasound-assistant exhaustion process on textiles, followed by the polysiloxane posttreatment.
First, a polysiloxane cream is applied to the skin, followed by a platinum catalyst that induces the polymer to harden and tighten the skin underneath.
In this article, thick (~15 pm) silicon-oxo-dominated nanocomposite coatings with high transparency were fabricated by incorporating 3-methacryloxypropyltrimethoxysilane (MPS)-modified silica alcosol into a moisture-curable polysiloxane oligomer and curing with the aid of 3-aminopropyllriehtoxysilane (APS).
The water absorption of block and graft waterborne polyurethane-polysiloxane copolymer films decreased from 163.9 to 40.2% and 17.3%, respectively, when percent of polysiloxane (w/w) increased from 0 to 5%, and the tensile strength of the block waterborne polyurethane-polysiloxane copolymer films decreased while the tensile strength of graft waterborne polyurethane-polysiloxane copolymer films increased with increase of percent of polysiloxane.
