IV. Application Method:
The key to using AB adhesive lies in maintaining precise mixing ratios. This product requires a weight-based mixing ratio. Therefore, accurately weigh both components before mixing: take 1 part A agent (300g) and pour it into a container, then add 1 part B agent (100g).
Thoroughly mix both components to ensure uniformity, preventing poor surface quality in the finished adhesive.
V. Storage and Precautions:
Avoid direct sunlight and high temperatures during use and storage to prevent gelation.
Typical shelf life is 3 months. Remaining adhesive may still be used after 3 months if properties remain satisfactory.
Do not return unused crystal adhesive to its original unmixed packaging to prevent gelation.
Minimize direct skin contact with the adhesive. If accidental contact occurs, wipe off with a dry cloth and rinse thoroughly with soapy water. Cleaning tools such as droppers, syringes, or containers can be sanitized with acetone or alcohol.
VI. Product Packaging: Packaged in sets of 4kg.
