The Dispersion Challenge
Finer. More Uniform. Significantly Better Performance.
Coarser particles lead to poor dispersion, weak interfacial bonding, and compromised fire performance. Our micronized pentaerythritol solves this at the source.

Surface defects and pinholes
Uneven foaming, weak char structure
How It Works
Strong Char. Stronger Protection.
Pentaerythritol acts as a carbon source in intumescent systems. Under heat, it promotes dehydration and crosslinking, forming a stable, expanded char that insulates the substrate and blocks heat and mass transfer.
1. Heating
Pentaerythritol begins to dehydrate and generate active intermediates.
2. Crosslinking
Intermediates react with acids and blowing agents to form a crosslinked carbon network.
3. Foaming
Non-combustible gases expand the softened layer, building up an intumescent char structure.
4. Char Layer
Stable, porous char insulates the substrate and protects against heat and flames.
Promotes Intumescence
Enhances Char Integrity
Reduces Heat Release
Improves Fire Resistance
Key Benefits for Formulators
Designed for Formulation Excellence
Ultra-Smooth Film
Ideal for high-end indoor/outdoor thin-film intumescent coatings.
Low Water Sensitivity
High purity limits moisture absorption, preventing coating blistering and ensuring long-term weatherability.
