The Dispersion Challenge. Solved.
Conventional Pentaerythritol
Agglomeration
Irregular particles lead to agglomeration and poor dispersion.
Poor Film Uniformity
Uneven distribution causes defects, pinholes and inconsistent appearance.
High Water Sensitivity
High hygroscopicity affects storage stability and coating performance.
Micronized Pentaerythritol (PE)
Narrow PSD
Tight particle size distribution for minimal agglomeration.
Rapid, Uniform Dispersion
Easily dispersed for smooth films and consistent performance.
Improved Storage Stability
Low water sensitivity ensures reliable processing and storage.
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
