Transparent silicone sealant

ZJ-686 transparent silicone sealant is a single component room temperature cured dealcoholized silicone sealant that has good adhesion to many materials (such as metal, plastic, ceramics, and glass) and can provide excellent sealing and waterproofing performance. Mainly applied to

1. Bonding and sealing of various lighting fixtures (such as LED bulb lights, lamp tubes, etc.);

2. Protection, bonding and sealing of electronic or circuit board components;

3. Bonding and sealing of parts, case, etc. in the instrument industry;

4. Other industries require adhesive sealing.

Product features

1. Easy to use, with good extrusion workability;

2. Good adhesion, able to bond multiple substrates without the need for primer;

3. Neutral curing, non corrosive to materials such as PC and copper;

4. Excellent high and low temperature resistance, capable of long-term operation from -40 ℃ to 180 ℃.

Operation and Safety
  • Anticipated matters:
  • Please read the safety manual before use to learn about preventive measures and safety recommendations. For chemicals that do not require labeling, observe in advance and take corresponding preventive measures.
  • Action:
  • The construction site should have a good ventilation system.
  • Surface treatment: The substrate surface needs to be dry and clean to remove stress, static electricity, dust, oil stains, etc.
  • Bonding: Squeeze the gel onto the cleaned surface with a glue gun to distribute it evenly. If the temperature is low, the curing time will be extended.
  • After applying the adhesive, please immediately assemble the components together so that the adhesive can achieve good wetting effect, which will help with the bonding effect.
  • If the assembled components are stored in a dry environment (with a relative humidity of less than 50%), it is recommended to increase the humidity to ensure a suitable curing and crosslinking speed.
  • Hazard indications/safety recommendations/transportation rules:
  • Wear protective gloves for long-term or repeated contact.
  • Keep away from heat sources/sparks/open flames. No Smoking. Keep the container tightly closed. Use explosion-proof electrical/ventilation/lighting equipment.
  • Transport according to non hazardous materials.
  • Cleaning:
  • After a certain period of curing, alcohol or acetone can be used to clean excess adhesive in a timely manner.
  • The fully cured adhesive is difficult to remove and may require long-term immersion in an alcohol solvent to remove.
