Rheology Additives: Increasing viscosity - Waterborne systems - Synthetic phyllosilicates



Synthetic phyllosilicates are crystallized from salt solutions under controlled conditions in a special process. They are ultrapure and the crystal structure is highly uniform. These very efficient products are used as sol premixtures/pregels and are characterized by colorlessness, high transparency, easy incorporation and considerable shear thinning. Apart from adjusting the rheological profile, they can also be used to increase the barrier properties and influence the conductivity.




BYK Additive Recommendations

RecommendationLAPONITE-EP

Highly shear thinning layered silicate rheological additive with organic modification for extra performance in difficult-to-thicken water-borne systems.
Used in surface coatings, household products and general and industrial applications. Recommended for systems containing higher levels of electrolyte.

LAPONITE-RD

Highly shear thinning layered silicate rheological additive for water-borne systems.
Used in surface coatings, household products and general and industrial applications. Also used to stabilize emulsions.
Synergistic benefits are developed when formulated in combinations with polymer based co-thickeners.

LAPONITE-RDS

Highly shear thinning layered silicate rheological additive for water-borne systems. Used in surface coatings, household products and general and industrial applications.
