Cellulose is the most abundant organic polymer on Earth and the main component of all plants. It makes sense to harness this resource and unlock its potential as a biomaterial. One development centered around this is Valida.
Valida is fibrillated cellulose manufactured by Sappi, a 100% natural, biodegradable and sustainable material produced by mechanically processing wood derived cellulose fibres down to their smallest components, resulting in innovative material properties.
These properties include excellent stabilizing potential, rheology modification and robustness. Valida’s unique rheology profile – high viscosity at rest, highly shear thinning and sprayable – make it a suitable material for many applications, including waterborne Paints and Coatings systems. In Paints and Coatings, fibrillated cellulose acts as multifunctional stabiliser mimicking synthetic solutions while improving the sustainability, reducing VOC content and carbon footprint. At the same time, Valida effectively enhances the rheology of the wet paint and provides reinforcement to the dry paint. The high viscosity at rest results in stable formulations with improved in-can stabilities, enhanced pigments’ s stabilisation and no syneresis. Furthermore, the thixotropic nature significantly enhances the anti-sagging of the paint, preventing dripping. In the dry paint, Valida solves the mud-cracking issue, providing also higher resistance to household chemicals and enhanced contrast ratio/hiding power.
We will cover how Fibrillated Cellulose is produced and the difference to other conventional celluloses on the market before moving into the most common features Valida will impart to formulations through case studies. We will finish with some considerations when using Valida. To unlock the functionalities of Valida in formulations, proper activation and addition is necessary. Valida also synergizes with conventional materials, boosting their effectiveness.
With this information, we hope to have inspired you to try Valida in your systems and take a meaningful step in the direction of sustainable product development.
