Applications 

1. For Unsaturated Polyester Resin Curing: N,N-Dimethyl-p-toluidine (DMPT, CAS 99-97-8) is a high-reactivity amine accelerator used with organic peroxides such as MEKP to cure unsaturated polyester resins at room temperature, enabling efficient production of FRP products, artificial stone and castings.

2. For Acrylic And Anaerobic Adhesives: In methacrylate-based systems, DMPT acts as an amine accelerator in redox initiator-accelerator combinations, supporting fast room-temperature curing of acrylic structural adhesives, anaerobic adhesives and sealants with improved cure-through and bond strength.

3. For Low-Temperature Curing And Gelcoat: DMPT promotes reliable curing at lower temperatures and accelerates gel time, making it a practical accelerator choice for gelcoats, casting resins and repair compounds that must cure consistently across seasonal temperature changes.

4. For Composite And Coating Manufacturing: As a curing accelerator for unsaturated polyester, DMPT helps composite and coating manufacturers control working time and curing speed in hand lay-up, spray-up and casting processes, supporting consistent output in FRP, flooring and industrial coatings.

5. Reliable Supply For Global Industry: Supplied as a high-purity liquid (99% min) with consistent quality, DMPT gives resin, adhesive and composite manufacturers a dependable amine accelerator with stable supply, flexible packaging and professional technical support.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
