Specifications
Main component Chloroprene rubber base
Color Yellowish white
Viscosity (Pa.s) 10 to 17
Solid content (%) 44 to 48
Specific gravity 0.9 to 1.0
Diluent Toluene, MEK etc.
St’d size 180 ml Tube/1 kg can or 15-kg can

Application Example
  • Bonding and fixing of components in non-conductive positions
  • For bonding of materials soluble in toluene, MEK (such as polycarbonate, Noryl, ABS or acrylics), please contact us beforehand.

※Please be sure to avoid any use of these materials in electronic components that are to be energized electrically to prevent tracking or similar problems.
We recommend applying our polyester resin-based self-extinguishing adhesives SC608Z2 and SC608LVZ2.

  • Application
    1. Clean and dry the surface of the substrate before application of the adhesive.
    2. Apply the adhesive uniformly, avoid forming too thick a layer. Apply the adhesive to both of the surfaces to be joined. This is not necessary for the simple fixing of a component.
    3. Dry the applied film for a few minutes until it loses its stickiness, then join the two surfaces under sufficient pressure. The joined pair can be handled after a few hours. Depending on the temperature and material, about 80% of the maximum strength is reached after about 24 hours.
  • Storage
    1. The product should be stored under conditions suitable for adhesives. Follow instructions in instruction manuals or as shown on the labels. The maximum shelf life of adhesives is one year. Use the lots out of a large quantity stored in order of age. Adhesives containing solvents are hazardous materials. Observe the provisions of fire prevention laws.

Notes  
  1. Check before operation
    Check the relevant material safety data sheet (MSDS) and instruction manuals for precautions required for operation.
  2. Operation environment
    • Keep ignition sources away.
    • Use a local ventilator to ensure sufficient air circulation.
  3. First aid
    • Learn action to take from the MSDS and instruction manuals.
    • In case of eye contact, vapor inhalation or swallowing, seek medical attention immediately.
  4. Storage
    Store the product in a tightly closed container in a predetermined dark place at room temperature lower avoiding direct sunlight.
  5. Prohibition of unintended use
    Never use the product except as an adhesive.
