1,3-Bis(trimethylsilyl)urea

1,3-Bis(trimethylsilyl)urea is used as a silylating agent for carboxylic acids and alcohols.

Properties Suppliers
Chlorotrimethylsilane

Chlorotrimethylsilane is a silyl halide. It has variety of uses in chemistry, both as a source of the trimethylsilyl group, and as an anhydrous source of chlorides. Chlorotrimethylsilane can also be used to increase the volatility of a compound, enabling gas chromatography of normally non-volatile substances such as glucose.

Methyl Hydrogen Silicone Fluid Technical 100%

Description
Synonyms: Polymethylhydrogen Siloxane Fluid; Methyl hydrogen silicone oil; Methyl hydrogen polysiloxane, Polymethylhydrosiloxane
Equivalent Brand: Dow Corning 1107; Wacker SILRES BS94; TSF484;
Cas No.: 63148-57-2
Methyl Hydrogen Silicone Fluid RJ-202 is nontoxic and insipid. As there are fair quantity of relatively active Si-H bonds inthemolecule, under the action of catalysts it can react with chemicals containing active groups, such as double bonds or hydroxyl groups.
This product can be converted into film and used to produce a resilient waterproof coating on various materials by using metal salt catalyst at low temperature. It equips itself with outstanding water repellent property which prevents damage due to moisture, as well as mildew and rust development. Besides, its high vapor permeability allows the material to breathe and let water, vapor escape to the outside without causing damage.
The quality of RJ-202 has already been approved by some of the world's largest gypsum board manufacturers.

Potassium Methyl Siliconate Technical 52%

Description

Chemical name: Potassium Methyl Siliconate; Methylsilanetriol potassiumsalt; Potassium methylsilanetriolate

CAS No.:31795-24-1

Molecular Formula: CH3K3O3Si

 

Equivalent Brand: Dow Corning 777, Wacker SILRES BS 16, Rhodorsil Siliconate 51T

 

Potassium Methyl Siliconate RJ-WP01 is clear water-dilutable potassium methyl siliconate solution. Designed to impart water repellency to a wide variety of substances, such as concrete/cement, sandstone, limestone, marble, granite and bricks, ceramics, gypsum and gypsum-based plasterboard, light fillers etc.The siliconate reacts with carbon dioxide (CO2) in the air to form an insoluble water-resistant treatment within 24 hours.RJ-WP01 is also particularly effective in preventing humidity from rising within walls(rising damp). For this application the product is injected into the walls.

 

Due to the competitive price, Potassium Methyl Siliconate RJ-WP01 is widely used in some large scale construction projects by our clients from all over the world, we supply 300MT Potassium Methyl Siliconate RJ-WP01 per month.
