Rapid results. A high throughput study is used to optimise a clear concrete sealer formulation
The amount of volatile organic compounds (VGG) used in coatings continues to be reduced, due to environmental legislation and much R&D is dedicated to reducing VOCs in coatings while maintaining the same performance and appearance attributes. Waterborne emulsions provide feasible solutions to the challenge of meeting VOC regulations. A high throughput facility expedites the choice of a coalescent package for a newly developed acrylic dispersion designed for the decorative concrete market. Environmental legislations mandating the reduction of VOCs in coatings continues to be a primary driver in the development of binder systems across various markets. Manipulation of various technologies is allowing far the design of acrylic binders with improved appearance and performance characteristics while having low VOC content. Critical formulation considerations help determine the viability of newly developed acrylic dispersions for low VOC applications and key among these formulation variables is the determination of optimum coalescent agents. A high throughput study was conducted to explore the effects of solvents and plasticisers on the appearance and chosen performance criteria of an acrylic water-based clear sealer formulation. A formulation space was identified that provided favourable performance for all criteria tested, following the mixing, testing and analysis, in under three weeks, of 320 different formulations.
