The primary use of Rain-X is for automotive applications. Commercially sold "Original Glass Treatment" is the original and most well known Rain-X branded product. It is a hydrophobic silicone polymer [3] that forces water to bead and roll off of the car, often without needing wipers. It is sold in bottles of 3.5 or 7 US fluid ounces (100 or 210 ...
Silicones also exhibit good chemical resistance and high-temperature resistance (205 °C, 400 °F and higher). For this reason, silicone molds are suitable for casting low-melt metals and alloys (e.g. zinc, tin, pewter, and Wood's metal). RTV silicone rubbers are, however, generally expensive – especially platinum-cure.
Silicone grease is widely used as a temporary sealant and a lubricant for interconnecting ground glass joints, as is typically used in laboratory glassware.Although silicones are normally assumed to be chemically inert, several historically significant compounds have resulted from unintended reactions with silicones.
As the temperature of the solution approaches the NPSHr, the pump stops pumping because the cleaning solution flashes to steam in the pump intake. Careful design of the pump is required to minimize NPSHr and allow pumping of high temperature cleaning solution. A typical parts washer is aqueous based but there are some types that use solvent.

The company experienced a system issue that affected multiple products including account withdrawals, peer-to-peer payment service Venmo, online checkout and crypto. PayPal said the issue, which ...
Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...
Our research group has pioneered methods to turn these stem cells into miniature heart tissues that can be used to model disease-in-a-dish, to identify new drug targets for the development of new ...
