Purchasing Guide

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

  • For procurement requirements that require the use of single component polyurethane sealant, it is recommended to prioritize confirming key technical parameters such as curing time, tensile strength, and elongation at break of the product to ensure its suitability for specific scenarios such as building joints or automotive manufacturing.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Such suppliers can usually provide more stable product supply.
  • In different application scenarios such as industrial equipment sealing or curtain wall engineering, attention should be paid to the weather resistance and bonding performance of single component polyurethane sealant to adapt to environmental conditions such as temperature differences or long-term UV exposure.
  • During the procurement process, the actual application cases of suppliers' products in fields such as rail transit or electronic packaging can be evaluated based on their industry performance and platform statistical information to assist decision-making.
