Material Compatibility Risks Overlooking the specific material type—whether Polyester, Epoxy, or Metal-based like Steel or Aluminum—often leads to poor adhesion or failure in application, so matching the putty material to the substrate and repair conditions is critical.
Certification Verification Insist on suppliers providing certifications such as ISO 9001, RoHS, and MSDS to ensure product quality, safety, and regulatory compliance, especially when sourcing internationally or for industrial use.
Functionality Alignment In practice, most buyers prioritize putty functions like waterproofing, sealing, and increased durability; selecting a product with the right functional attributes such as moisture proofing or excellent covering directly impacts the effectiveness of the repair.
Shelf Life Considerations A critical question to pose your supplier is the exact shelf life—ranging from 12 months to 3 years—as this affects inventory turnover and potential waste, influencing overall procurement cost efficiency.
