Triglycidyl Isocyanurate(TGIC) CAS 2451-62-9 Curing Agent
As a reliable Triglycidyl Isocyanurate supplier, we specialize in providing high-purity TGIC crosslinkers designed for premium industrial applications. Our dedicated technical team ensures consistent batch quality to support your formulations worldwide.
- High Crosslinking Efficiency: Forms a dense, chemically resistant molecular network when reacted with carboxyl-functional polyester resins (typical formulation ratio around 7:93).
- Superior Outdoor Weatherability: Ensures long-term gloss retention, chalking resistance, and UV stability for architectural and industrial metal finishes.
- Thermal & Color Stability: Minimizes thermal degradation and prevents yellowing during extended or high-temperature curing cycles.
- Low Volatile & Epichlorohydrin Content: Strictly controlled impurity levels (<50 ppm Epichlorohydrin) ensure safer handling and stable processing behavior.

1,3,5-Triglycidyl isocyanurate Applications
- Polyester Powder Coatings: Primarily used as a crosslinking curing agent for pure polyester powder coatings (ratio approx 7:93). It provides outstanding weatherability, chemical resistance, and corrosion protection for outdoor metal substrates.
- Electrical Insulation Materials: Used in the production of electrical insulating laminates, printed circuit board (PCB) solder masks, adhesives, and plastic stabilizers due to its excellent dielectric properties.
FAQs about Triglycidyl Isocyanurate (TGIC)
Q1: What is the primary role of TGIC in powder coatings?
TGIC acts as a highly efficient crosslinking/curing agent for carboxyl-terminated polyester resins. It reacts with the carboxyl groups to form a dense, three-dimensional network structure, which gives the final powder coating excellent weather resistance, heat resistance, and chemical stability.
Q2: How should TGIC be handled safely during operation?
TGIC is a hazardous chemical that requires careful handling. Operators should wear appropriate personal protective equipment (PPE), including dust masks, safety goggles, and protective gloves, to avoid direct skin contact or dust inhalation. Ensure proper local exhaust ventilation in the mixing area.
Q3: What is the recommended dosage of TGIC in pure polyester powder coatings?
The standard formulation ratio is typically 7:93 (TGIC to carboxylated polyester resin), depending on the acid value of the polyester resin used.
Q4: Can TGIC be used for indoor powder coating formulations?
While it can be used, TGIC is highly optimized and valued for its outdoor UV and weather resistance. For purely indoor applications (like appliances or indoor furniture), epoxy-polyester hybrid systems (Primid or Hybrid) are often selected as cost-effective alternatives.
