Bio-based reinforcement agent
Exilva® Reinforcement Agent
Bio-based film reinforcement for stronger, more durable coatings.
Exilva® is a next‑generation, bio-based, EU Ecolabel‑compliant, dust‑free additive designed to reinforce the coating film at the microscopic level, delivering improved mechanical durability, crack resistance, and long‑term performance without compromising formulation properties or appearance.
Its patented technology forms a strong, continuous network within the coating, enhancing the integrity of the film beyond what conventional mineral or synthetic fibers can achieve.
Bio-based & sustainable
EU Ecolabel-compliant, replaces fossil‑based and mineral fiber technologies.
Advanced micro‑scale reinforcement
Unlike conventional fibers, which act as discrete particles, Exilva® delivers continuous reinforcement throughout the film.
Performance without trade-offs
No brittleness or embrittlement often associated with rigid mineral fillers.
Dust‑free & easy to handle
Cleaner processing and improved operator safety.
Technical highlights
- VOC content: 0 g/L
- Odor: Odorless
- Recommended dosage: 1.0–3.0 wt% (add during grind)
- Appearance: White paste
- Mechanism: Creates a continuous network within the binder phase. Due to the extremely small size of the fibrils, this reinforcement occurs at a scale that is invisible to the eye, ensuring a smooth and uniform coating surface without visible particles or fiber structures.

How Exilva help
HIGHER MECHANICAL STRENGTH
Enhances tensile strength and film cohesion, leading to more robust coatings.
ELIMINATES MICRO-CRACKING
Extends durability and reduces costly rework.
ENHANCES DURABILITY
Provides reinforcement without making the film rigid or fragile.
UNIFORM REINFORCEMENT
Fibrillar network ensures homogeneous performance throughout the film.
Formulation advantages
- Drop-in additive → No complex reformulation needed
- Universal resin compatibility → Works across major water-based resin technologies
- Can reduce or replace → Mineral fibers and synthetic reinforcement additives.
- Maintains application properties and rheology.
- No sedimentation or fiber flocculation issues.
Exilva® – Reinforcement without compromize.
