Purchasing Guide

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

  • For procurement requirements that require the use of unsaturated resins, it is recommended to prioritize confirming key technical parameters such as viscosity, acid value, and solid content, which directly affect their processing performance in fiberglass products or coatings.
  • Unsaturated resin is widely used in automotive parts and shipbuilding, and different chemical properties such as ortho - or meta benzene can be selected for procurement based on specific scenario requirements.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • If purchasing unsaturated resin for anti-corrosion engineering, additional attention should be paid to its acid and alkali resistance and thermal stability parameters to avoid affecting the final product life due to insufficient material properties.
