Purchasing Guide

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

  • For procurement requirements that require the use of sealing agents, it is recommended to prioritize confirming key technical parameters such as solid content, viscosity, and chemical resistance of the product to ensure its suitability for different scenarios such as metal corrosion prevention or concrete sealing.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable sealing agent supply solutions.
  • In the field of industrial coating, the selection of sealing agents should be based on the type of substrate and environmental conditions. For example, in high-temperature environments, thermal stability parameters should be considered, while in outdoor applications, UV resistance performance should be taken into account.
  • When purchasing sealing agents, it is recommended to compare the performance of different suppliers in segmented industries such as automotive manufacturing and electronic packaging, and select solutions that are suitable for product specifications based on specific application scenarios.
