704 one-component room temperature vulcanized silicone rubber, metal and plastic sealing adhesive

Product model: SD704W one-component room temperature vulcanized silicone rubber

Characteristics: 704 one-component room temperature vulcanized silicone rubber, white paste. Room Temperature Vulcanizing Silicone Rubber (RTV, Room Temperature Vulcanizing Silicone Rubber) is a silicone rubber material that can cure itself at room temperature. It is a polymer made of silicon chains that can solidify into elastic rubber through a vulcanization reaction through contact with moisture in the environment.

 

Room temperature vulcanized silicone rubber is widely used in electronics, electrical, aerospace, medical, construction and other fields. Specific applications include:

1. Electronic and electrical field: sealing, insulation and protection of electronic components, circuit boards, etc.

2. Automobiles and vehicles: sealing, waterproofing and shock-absorbing devices.

3. Construction and home furnishing: sealing, waterproofing and caulking, etc.

4. Medical field: production of medical devices, artificial organs and medical seals, etc.

Packaging, storage and transportation requirements

Transportation: There are no regulations for domestic (CN-GB) and international (IMO, IATA, UN). It is a non-dangerous goods.

 

Package:

①The packaging of materials has a certain protective and sealing effect on the materials to ensure that the materials are not damaged during transportation.

② The product model, name, quantity, manufacturer’s trademark, production batch and other information should be printed on the packaging box.

③The packaging box should meet the requirements of moisture-proof, shock-proof, pressure-proof and mildew-proof.

 

store:

Products packed into boxes should be stored in a cool, dry environment with an ambient temperature below 26°C. There should be no acid, alkaline or other corrosive gases in the surrounding air. Under the above conditions, the storage period can be six months from the production date. The six-month-old material is still qualified.

Packaging specifications: 50ml aluminum tube, 330mlPE tube
