typical application:
1. Weatherproof sealing of building exterior walls, roofs, doors and windows.
2. Auxiliary sealing of the joint between the outdoor reservoir and the tank.
3. Sealing of indoor HVAC channels.

Construction tips:
1. Remove all putty, rust and water from the glued area.
2. Choose the appropriate cushion material to fill the seam according to the seam design specifications.
3. In order to keep the glue flat and beautiful, masking paper can be attached to both sides of the seam for protection,
and the surface should be trimmed and peeled off before the glue is peeled.

Precautions for use:
1. Due to the difference in materials and the different construction environments, it is recommended to perform adhesion tests on the construction environment and the substrate to ensure specific bonding purposes.
2. Under extreme application conditions, such as high temperature, high humidity, high pH, ​​long-term immersion in oil or water, etc., the applicability needs to be tested before application.
3. Applying glue at a low temperature below 5 ° C or a material surface temperature exceeding 50 ° C will affect the final adhesion, and proceed with caution.
4. S168 is used with caution in the following situations:
● All material surfaces that can ooze grease, plasticizers or solvents.
● Discoloration or corrosion may occur on the surface of copper metal.
Safety Tips: Please read the relevant product safety information in the product MSDS carefully before using. For more information, please contact Qingdao Lida Chemical Co., Ltd. or obtain it from the agent distributor.
