Instructions for Use:
1. Weighing: First, mix component A and component B evenly, and then weigh component A and component B in a 1:1 weight ratio.
2. Mixing: Mix the two components of the adhesive thoroughly, preferably using specialized mixing equipment (such as a small planetary mixer). When mixing by hand, attention should be paid to stirring in the same direction, otherwise too many bubbles will be mixed in; Also, it is necessary to scrape the bottom and side walls of the mixing container, otherwise local unevenness may occur due to uneven mixing.
3. Defoaming: Vacuum degassing in specialized mixing equipment. Alternatively, the mixed rubber material and mixing container can be placed in a vacuum defoaming device and vacuumed for defoaming treatment. During the vacuum degassing process, the liquid level of the mixture may rise to 3-4 times the original volume, and then automatically burst and collapse. After breaking the bubble, maintain the vacuum for 4-6 minutes, and finally release the vacuum.
4. Glue filling: Slowly pour the prepared adhesive into the area that needs to be sealed. Let it stand at room temperature for natural curing, or it can be heated to accelerate curing.
Notes:
1. Due to the high risk of catalyst deactivation caused by poisoning, it is recommended to avoid contact with certain fluxes and latex gloves containing materials such as tin, sulfur, phosphorus, amines, etc., and to keep the containers clean.
2. The ambient temperature has a certain impact on the operational applicability and curing speed of K-76002 after mixing. When the ambient temperature is high, the operating period and curing speed are shortened.
If there are doubts about whether a certain object or material will cause hindrance to curing, it is recommended to conduct a small-scale compatibility test to determine its applicability in this application.
If there is liquid or no solidified substance on the surface of the object in question and the cured gel, it indicates that there is no compatibility, which will hinder the curing.
Storage:
Layered phenomenon may occur during storage, so it is necessary to stir independently and evenly before use. It should be stored in a cool and dry place to prevent exposure to sunlight and rain. AB is stored between 0 ℃ and 30 ℃, with a shelf life of 6 months under sealed conditions in its original packaging
