Category overview
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.

FAQs
Why does a waterborne coating need pH stabilization?
Many ingredients, like certain resins, thickeners, and dispersants, only perform correctly within a specific pH range. Without stabilization, pH can drift, causing viscosity changes or reduced shelf life.
pH stabilizer or buffer: when to choose what?
A stabilizer adjusts or holds pH at a target level. A buffer specifically resists pH change when acid or base is introduced, offering more robust, ongoing stability than a one-time adjustment.
Can pH stabilizers affect viscosity?
Yes, indirectly since many thickeners/dispersants are pH-sensitive, a pH shift can trigger unexpected viscosity changes even without an obvious cause.
How often should a coating's pH be checked during production?
Typically at multiple points: raw material receipt, after mixing, before packaging, since ingredient variability and processing can shift it.
Can incorrect pH cause corrosion inside a metal can?
Yes, if pH drifts too acidic, it can accelerate can corrosion, causing gas buildup, bulging, or metal contamination. Proper stabilization protects both product and packaging.
