All Catalyst™ tools by Princeton Artist Brush Co. have been discounted at 20% off and we will no longer be carrying the brand: when our remaining inventory is gone, it’s gone, so stock up now! Ergonomically crafted from flexible silicone or durable nylon and designed for use with heavy-bodied paints, Catalyst is at home with oils, acrylics, and water-miscible oils. Because they are heat-resistant, they excel with encaustics. Artists are using them with plaster, clay, and even buttercream frosting (FDA-approved silicone makes the blades and wedges ideal for food crafting). Catalyst tools are easy to wipe clean, solvent resistant, and dried paint can be peeled off the silicone surface.
