　　Performance characteristics of 107 silicone rubber

　　107 silicone rubber is an organic silicon material that is polymerized from siloxane monomers and has hydroxyl groups at both ends of its molecules.

　　Its structural formula is as follows: HO Si (Cspan) 2 O [Si (Cspan) 2 O] nSi (Cspan) 2-OH

　　The chemical name is a, w-dihydroxypolydimethylsiloxane, and it is customary to have a viscosity of 2500mPa Hydroxysilicone oil with S or higher is called 107 silicone rubber. In addition to the general properties of methyl silicone oil, this product also has hydroxyl reactivity, which can be used to make some new materials or crosslinked into elastomers (or membranes).

　　This product is a colorless and transparent liquid with excellent electrical insulation and resistance to high and low temperatures. It has a high flash point and a low freezing point, and can be used for a long time under the conditions of -50oC to+250oC. It has a low viscosity temperature coefficient, high compression ratio, low surface tension, good hydrophobicity and moisture resistance, chemical inertness, and physiological inertness.

　　Technical indicators of 107 silicone rubber

　　Appearance: Colorless and transparent liquid.

　　Viscosity (25oC, mpa. s): 50-100000 (customizable according to user requirements).

　　Hydroxyl content (%): 0.5-3 (directly related to viscosity).

　　[Application of 107 Silicone Rubber]

　　Used as the main raw material in RTV mold silicone rubber, defoamer, and silicone glass adhesive.

　　1. Due to its excellent electrical insulation properties, it can be used as an insulation, moisture-proof, shock resistant, and heat-resistant sealing material for electronic components and assemblies such as radios, electronic instruments, semiconductors, etc.

　　2. We produce rubber roller materials in the automotive and mechanical industries.

　　3. Rubber roller materials are used in the textile, plastic, and printing industries.

　　4. Sealing materials for joints in the construction industry.

　　5. It has excellent demolding properties, especially suitable for manufacturing precision molds and impression materials.

　　[107 Silicone Rubber Usage and Dosage]

　　Generally used in conjunction with curing agents to achieve cross-linking curing. When used for anti sticking paper, coupling agents are also required for fixation. The amount of curing agent generally accounts for 3-5% of the base adhesive, and the coupling agent accounts for 0.5-1% of the base adhesive. In most cases, the base adhesive is diluted 10 times with a solvent, and then the curing agent and coupling agent are added and stirred evenly before being coated on the surface of the substrate. It is cured at room temperature or by heating. At room temperature, it takes more than 30 minutes, and heating at 120-150oC takes 30 seconds. Used for sealant and mold base adhesive without the need for solvents. After adding the curing agent, stir well (single component and two-component use different curing agents), and cure after 30-120 minutes of defoaming.

　　[Precautions for 107 Silicone Rubber]

　　Do not mix with acidic or alkaline substances, alkoxysilane, and water vapor at high temperatures, otherwise there is a tendency for solidification and viscosity changes.

　　107 Silicone Rubber Packaging and Storage Transportation

　　1. This product should be stored in a clean plastic drum and should not come into contact with strong acids or alkalis;

　　2. Store at room temperature in a well ventilated and cool place;

　　3. Storage and transportation of non-toxic and non hazardous materials.
