Mainly used for electronic components heat bonding, light curing can not be cured by moisture, the product has a good waterproof function, the colloid has a certain toughness and surface hardness.
Instructions for use:
- Keep containers sealed and stored away from water, moisture, heat and light.
- It is recommended to use alcohol to clean the uncured product if there is a problem.
- Already cured products if there is a bad recommendation to use heating or with a degumming agent to rework.
Note:
- Keep away from children.
- This product is recommended for use in well-ventilated places. Avoid contact with skin and eyes. Take care to avoid ingestion, practice good industrial hygiene, and wash after handling, especially before eating or smoking.
- The curing speed depends on the intensity of the lamp, the distance between the light source and the adhesive layer, the depth of curing required or the adhesive layer gap, and the light transmittance of the substrate.
- In case of contact with skin, rinse immediately with soapy water.
- If it spills into eyes, rinse immediately with water and seek medical attention.
