Engineered for Performance in Real Applications
1. Intumescent Fire-Resistant Coatings
Mechanism
Acts as an effective carbon source with APP/Melamine, promoting the formation of expanded, cohesive char layers to insulate and protect the substrate.
Advantages
Ultra-fine particles deliver uniform dispersion and compact formulation.
Low water sensitivity ensures stable processing and long term storage.
High char yield and integrity for superior fire protection.
Typical Applications
Steel structure coatings
Cable fire-protective coatings
Decorative fire-retardant coatings
Compatible Resin Systems
Epoxy, Acrylic, Polyester, Polyurethane, Alkyd

2. Flame-Retardant Inks
Mechanism
Works synergistically with flame retardants to enhance char formation and reduce heat release during combustion.
Advantages
Ultra-fine particles for no screen clogging and excellent printability.
Good dispersion without affecting gloss, color or adhesion.
Low hygroscopicity for stable viscosity and storage.
Typical Applications
Cable marking inks
Textile printing inks
Decorative and outdoor inks
Compatible Resin Systems
Acrylic, Polyurethane, Epoxy, NC, UV-curable

3. Resin Formulations
Mechanism
Serves as an efficient carbon source with APP/Melamine systems to improve char stability and flame retardancy of polymers.
Advantages
Compatible with a wide range of polar and non-polar resins.
Uniform dispersion for consistent performance.
Thermal stability to support high processing temperatures.
