Synopsis

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.
At the same time, Valida effectively improves the rheology of wet paint and provides
reinforcement to the dry paint.
The high viscosity at rest results in stable formulations, better in-can stability and pigments’s
stabilisation, and, ultimately, in reduced/solved syneresis.
Furthermore, the thixotropic nature significantly enhances the anti-sagging of the applied
layer, preventing dripping.
In the dry paint, Valida solves the mud-cracking issue, provides better resistance to
household chemicals and improves the contrast ratio/hiding power, complementing the TiO2
and boosting its opacity performances.
