ACI Adhesive Anchor Installer Certification Practice Exam

What should be checked on a foil capsule immediately before use?

1. For color uniformity

2. For pliability and that the adhesive has not hardened

3. For any leaks in the packaging

4. For the expiration date

The correct answer is: For pliability and that the adhesive has not hardened

Checking for pliability and ensuring that the adhesive has not hardened is critical immediately before use of a foil capsule. Adhesive formulations can change over time, and exposure to certain conditions can lead to the adhesive curing or hardening inside the capsule. If the adhesive has hardened, it will not perform properly during the anchoring process, which could result in inadequate bond strength. Ensuring that the adhesive is pliable ensures that it will flow properly when dispensed and will bond effectively with the materials it is intended to adhere to during installation. Although checking for color uniformity, packaging leaks, and expiration dates are important quality control measures, they do not directly impact the immediate usability of the adhesive on the day of installation. Ensuring that the adhesive is still pliable and functional is paramount to achieving a successful anchoring job, making this check the most critical step just before using the adhesive capsule.
