pH-Stabilizers / Buffers

Based on 52 products - Last update on the Jun 26, 2025

Buffers are clear to slightly opaque liquids or crystalline powders. They ensure pigment dispersion, formulation stability, and proper curing behavior. They are used in waterborne coatings, ink formulations, and corrosion-resistant primers. 

Natural and biodegradable buffering agents are being explored as alternatives. Trends in hybrid waterborne formulations have driven the need for tailored buffer solutions. Certain buffers are subject to regulatory concentration limits in environmentally certified coatings.
