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.

Typical Applications

Epoxy resin systems
Acrylic resin systems
Polyurethane resin systems

Compatible Resin Systems

Epoxy, Acrylic, Polyurethane, Polyester, Polyolefin
