Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of waterproof sealant, it is recommended to prioritize confirming key technical parameters such as tensile strength, elongation, and weather resistance of the product to ensure its suitability for different scenarios such as building joints or underground engineering.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually provide more stable product performance and delivery guarantees.
  • In high-frequency vibration environments such as industrial equipment or outdoor facilities, it is recommended to choose waterproof sealant with high elastic recovery rate to reduce the risk of cracking after long-term use.
  • For applications in humid environments such as bathrooms and kitchens, attention should be paid to the product's anti mold performance and the compatibility of the bonding substrate to avoid sealing failure due to environmental humidity.
