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 and highly shear thinning – 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.
Valida effectively improves the rheology of wet paint and provides reinforcement to the dry paint. The high viscosity at rest results in stable formulations over time, improved in-can stabilities, pigments’s stabilisation and reduced/solved syneresis. Its thixotropic nature enhances the anti-sagging and anti-dripping of the applied layer.
Through its non-soluble 3D-fibrils network, Valida boosts chemical and stain resistance as well as it provides physical reinforcement, such as increased wet-scrub resistance, higher tensile strength, adhesion to substrate and solved mud-cracking issues.
We will cover how Fibrillated Cellulose is produced and what functionalities Valida delivers to waterborne coating formulations, as Elastomeric Roof Coatings and Interior wall paint.
We will finish with some considerations when using Valida and best practices to unlock the functionalities of Valida in formulations.
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.
