Wesbond - Pigment Suspending Agent

Wesbond PSA

Pigment suspending agent

Wesbond PSA is a pigment suspending agent designed for use in colloidal silica/pigment slurries for coloring and hardening of ceramic fiber shapes like fireplace logs. It performs exceptionally well for suspending pigments used in slurries for dipping, spraying, and brush-on applications. Wesbond PSA is an all inorganic magnesium aluminum silicate powder with a pH similar to that of colloidal silica (9-10) and high temperature properties similar to the ceramic fibers used in vacuum formed fireplace logs.

Wesbond PSA offers these advantages

Easier mixing

Improves pigment suspension and reduces settling to make mixing easier.

Improved Color Uniformity

Suspends and disperses pigment for more uniform color.

Improved hardness

Colloidal mineral blend creates stronger, more durable coatings.

Significantly Lower Costs

WesBond PSA improves pigment surface retention reducing overall pigment use by up to 50% - a significant cost reduction. It also replaces up to 10% of expensive colloidal silica, bringing your overall formulation costs down.
