EVERCOAT® 100733 Polyester Primer Catalyst is a 946 mL, 4:1 mix ratio catalyst designed for use with polyester primers in automotive body repair. It provides the chemical activation required to achieve a durable, adhesion‑promoting film on compatible substrates such as fiberglass, polyester, SMC, wood, and existing primer coats.
The catalyst is formulated to work with a broad range of polymeric substrates, ensuring consistent wet‑out and film formation across typical body shop repair materials. Its high reactivity supports efficient processing while maintaining the mechanical properties needed for subsequent topcoat applications.
Due to its acute toxicity, carcinogenicity, and flammability, appropriate personal protective equipment—including eye protection, chemical‑resistant gloves, protective clothing, and a respirator—is required. Use in a well‑ventilated area and follow standard first‑aid procedures for inhalation, skin, eye, and ingestion exposure as outlined in the SDS.
