CNSL Polyurethane Solutions

Meet the demands of modern applications

Polyurethane Chemistry

Polyurethane bonds form by reacting diisocyanates with polyols, creating a segmented polymer network:

Soft segments (polyols/diols): Provide elasticity, resilience, and low-temperature flexibility
Hard segments (diisocyanate/chain extender): Contribute hardness and structural strength

Common building blocks:

Diisocyanates: TDI, MDI/PMDI, HDI, IPDI
Polyols/diols: Polyethers, polyesters, castor-derived, polycarbonates, polycaprolactones, amine-terminated, acrylic polyols

Customizable with additives:

Catalysts, surfactants, moisture scavengers, diluents
Flame retardants, pigments, fillers

Key benefits:

Mechanical strength and adhesion
Weatherability and abrasion/tear resistance
Versatile use in coatings, adhesives, foams, elastomers, and more

CNSL Polyurethane Solutions

Meet the demands of modern applications

Hydrophobicity

Cardanol’s long aliphatic side chain provides inherent hydrophobicity, helping enhance polyurethane formulation water resistance and minimize moisture-related issues during cure.

Key benefits include:

Adhesion to damp substrates
Hydrolytic stability for long lasting protection
Good appearance of the final product in humid conditions

Learn More

Tailored reactivity

CNSL-based polyols and diols provide fast cure with minimal additional catalysts, enabling efficient crosslinking and strong network formation even at ambient conditions.

This helps to:

Simplify formulations, reducing overall system cost
Accelerate return-to-service for enhanced productivity

Learn More

Aromatic advantage

The aromatic backbone of CNSL polyols differentiates them from other natural oil-derived polyols like soy or castor oil. This feature provides enhanced durability and mechanical properties that are difficult to achieve using other bio-based polyols.

Including:

Higher strength
Better thermal stability
Improved chemical resistance
