Salinity is approximately equal to the weight, in grams, of salt dissolved in 1000 g of seawater. This would be the salt concentration in parts per thousand (). Average ocean water has a salinity of 35.0. This means that 1000 g of average seawater contains 965 g of water and 35 g of salts.
From Wikipedia, the free encyclopedia. RTV Silicone (room temperature vulcanization silicone) is a type of silicone rubber made from a two-component system (base plus curative; A+B) available in a hardness range of very soft to medium-usually from 15 Shore A to 40 Shore.n order for the RTV silicone to reproduce the surface texture, attention is paid to the cleanliness of the original. Vacuum deairing removes entrained air bubbles from the mixed silicone and catalyst to ensure optimal tensile strength, which affects reproduction times.
Effects. RTV sealant is stored in airtight squeeze tubes. When the RTV sealant is squeezed out of the tube onto a surface, the material comes in contact with moisture in the air, triggering the reaction that will cause it to cure and harden.RTV sealant is useful for a variety of applications, including sealing gaskets in cars and boats, and engine repair.oom-temperature vulcanization (RTV) sealants are made of silicon polymers that become cross-linked in a reaction that takes place at room temperature.
