SAFETY

HAZARD NOTES

Highly toxic by skin absorption, Corrosive. Ingestion (swallowing) of liquid chlorosilanes may cause severe internal injury or death. The chlorosilanes all react with moisture in the air or water to produce hydrogen chloride, the principal reaction product that can cause acute injury to any body tissue contacted. The major acute health risks are potentially severe corrosive burns of the skin, eyes or respiratory tract.

EYE

Causes eye burns.

SKIN

Causes skin burns. May be fatal if absorbed through skin.

INGESTION

May be harmful if swallowed. Causes burns.

INHALATION

May be harmful if inhaled. Material is extremely destructive to the tissue of the mucous membranes and upper respiratory tract.

Although Organosilane might seem like a confusing compound, it is actually quite useful in many different situations. First of all, it is used in mixtures with hydrogen peroxide. When the peroxide is mixed with an Organosilane quaternary compound in an aqueous formulation, the mixture can be used to improve the way that water and soil can be repelled from surfaces. This creates a coating composition that is at the same time used for cleaning, as well as other multifunctional coating purposes.
Because of the unique properties that Organosilanes have, they can repel water, dirt, and other substances away from the item that they coat. Therefore, a mixture of Organosilane and hydrogen peroxide can be applied to an item, and it will give the item a protective coating that cannot be penetrated. There are many different surfaces that benefit from being coated with the Organosilane mixture. These surfaces include metal, plastic, glass, rubber, ceramic, porcelain, marble, cement, granite, tile, silica, sand, appliances that have been enameled, polyester, polyurethane, polyacrylic, resins that are melamine or phenoilic, siliceous, polycarbonate, and wood, as well as painted surfaces. This is an incomplete list, as there are many different surfaces that can benefit from being coated with the Organosilane that is now used in many different situations.

There are many uses for Siloxane; all of this proves to be quite useful for the common person. Siloxane, most of the time, is used in many different products like cosmetics, deodorants, and defoamers. These are three of the main types of products that contain Siloxane, and the Siloxane in them is used there because of its natural bonding properties. There are also Siloxane components that are found in products that repel water, such as those that coat windshields. Also, Siloxane is found in food additives, and can be found in some soaps as well .Therefore, Siloxane is something that is found in many different types of products, occurring all over the world.

Often the silane is subjected to hydrolysis prior to the surface treatment. Following hydrolysis, a reactive silanol group is formed, which can condense with other silanol groups, for example, those on the surface of siliceous fillers, to form siloxane linkages. Stable condensation products are also formed with other oxides such as those of aluminum, zirconium, tin, titanium, and nickel. Less stable bonds are formed with oxides of boron, iron, and carbon. Alkali metal oxides and carbonate do not form stable bonds with Si-O. Sufficient water for hydrolysis may be available from atmospheric moisture, or on the substrate surface. In some cases, it may be necessary to add water to increase the degree of hydrolysis. The most straightforward method of silylating a surface with silane is from an alcohol solution. A two percent silane solution can be prepared in the alcohol of choice (methanol, ethanol, and isopropanol are typical choices). The solution can be wiped, dipped, or sprayed onto the surface. When dipping a large object, e.g., glass plates, allow one to two minutes of submersion to allow silane migration to the surface. After the surface dries, excess material can be gently wiped, or briefly (alcohol) rinsed off. Particles, e.g., pigments and fillers, can be silylated by stirring them in a solution for two to three minutes and then decanting the solution. The particles can then be rinsed with alcohol. Cure of the silane layer is for 5-10 min at 110°C or for 24 hr at ambient conditions. There are three basic methods of utilizing silanes in a coatings application: (1) surface treatment, which includes particle (i.e.,pigments and fillers) treatment formulated into primers, and water repellents; (2) additive into paints, inks, and adhesives; and (3) reactive intermediate for silicone resin synthesis and organic resin modification. Each of these methods requires special consideration.(http://www.dowcorning.com/)
