BIO-BASED ANTI-SAGGING ADDITIVE
Exilva® Anti-Sagging
Bio-based additive for superior sag resistance
without viscosity increase.
Exilva® is an innovative, bio-based, EU Ecolabel-compliant, APE- and VOC-free additive that delivers exceptional anti-sagging performance in waterborne coatings.
Unlike traditional thickeners or clay-based systems, which rely on increasing low-shear viscosity to control sagging, Exilva® provides sag resistance through yield stress, without significantly increasing KU viscosity.
Bio-based & Eco-compliant
Supports sustainable formulations and green building certifications.
Performance without trade-offs
Maintains scrub resistance, block resistance, colorant compatibility, and stability.
Applications
Suitable for spray coatings and for brush and roller coatings together with a Newtonian thickeners.
Coating types
Architectural, industrial, wood and decorative coatings.
Technical highlights
- VOC content: 0 g/L
- Odor: Odorless
- Recommended dosage: 1.0–3.0 wt% (add during grind)
- Appearance: White paste
- Mechanism: Patented technology forms a threedimensional
fibrillar network through hydrogen bonding, generating high yield stress at low shear while maintaining strong shear‑thinning behaviour during application.
Performance snapshot
| Main property | With Exilva | Without Exilva |
| Sag resistance | 2-3 x improvement | Moderate |
| KU viscosity | No significant change | Increased |
| Application feel | Smooth, low drag | Higher drag |
| Over-grinding sensitivity | None | Posible |
How Exilva help
2–3 x SAG RESISTANCE
Enables application of thick wet films on vertical surfaces without impacting levelling.
NO INCREASE IN KU VISC.
Maintains pumpability, sprayability, and application feel, unlike conventional rheology modifiers.
IMPROVED APPLICATION FORGIVENESS
Reduces sensitivity to application variations, enabling more consistent film quality.
WIDE COMPATIBILITY
Effective across acrylic, PU, styrene acrylic, vinyl acetate, VEOVA systems.
Formulation advantages
- Enables high sag resistance without thickening → No negative impact on levelling
- Compatible with → All major waterborne resin systems; Other rheology modifiers.
- Improves process robustness & consistency → Not sensitive to over‑grinding.
