Acrylic Resins for Stain-Blocking Primers

An important characteristic of acrylic paint primers is the ability to resist and even block paints. At Gellner Industrial, we’ve developed several cationic acrylic resins that are perfect for primers that need to better block and resist stains.

The Benefits of Gellner’s Cationic Acrylic Polymers

Nearly all of the surfaces found in the world are anionic, meaning they have a negative charge. As a result, cationic polymers that are positively charged, can greatly improve a primer’s adhesion, as well as its general resistance to its environment. Our cationic acrylic resins are formulated to add stain-blocking properties to a primer or paint without the need for other additives, and some can even block stains that other polymers can’t, such as tannin oils, stains from water-based materials, and fungal growth.
