Poly Putty
Description
Poly Putty is made by refining unsaturated polyester resin, modified resin, pigments, fillers, and various additives, and is used by mixing with a curing agent in a certain proportion. It is mainly used for filling and repairing defects such as pits, pinholes, cracks, and small welds on the substrate before sealing the intermediate coating in the repair process of automobiles and buses, ensuring the flatness and smoothness of the substrate surface before applying the topcoat.

| Application Method | 1. Mix the main putty and hardener evenly at a ratio of 100:2 (ensuring uniform color) and use it within the gel time (typically 5–15 minutes). 2. Apply the mixed putty to the sanded two-component primer or pre-treated cold-rolled steel surface. For thick applications, apply in multiple thin layers until the desired thickness is reached. If air bubbles appear during application, use a spatula to smooth the surface thoroughly to ensure good adhesion. 3. The optimal wet sanding time is 0.5–1 hour after application, while the optimal dry sanding time is 2–3 hours after application. |
