Triglycine as an innovative functional additive for water-based and solvent-borne coating systems, targeting one of the most common defects during application: visible brush marks and uneven film formation. It modifies the rheological behaviour of wet coating layers and facilitates uniform spreading before crosslinking and curing, delivering a smoother, more consistent finished surface.
Brush marks typically arise when the wet coating fails to flow out quickly enough after mechanical spreading, leaving linear traces created by bristles or applicators. Triglycine interacts with resin molecules and dispersed pigment particles through hydrogen bonding, lowering local surface tension gradients across the wet film. This balanced surface tension permits gentle, controlled flow without triggering sagging or drips on vertical substrates. Unlike many conventional leveling agents that may compromise adhesion or introduce foam, triglycine works with mild interfacial regulation and maintains stable compatibility with a wide spectrum of coating formulations, including architectural paints, industrial topcoats and decorative wood finishes.
For coating formulators, this new component brings practical advantages in production and end performance. It can be incorporated during the grinding or letdown stage without demanding special high-shear processing. After application, it helps the wet film relax and merge micro-flow irregularities, fading out fine brush streaks and orange-peel texture. Once cured, the resulting coating exhibits better gloss uniformity and a continuous surface, which also enhances scratch resistance and dirt repellency by reducing tiny surface valleys where contaminants tend to accumulate. It retains its performance through standard curing cycles and does not readily migrate to the surface to form greasy blooms.
Applicators benefit greatly from this formulation upgrade. Even for hand-brushed jobs that are harder to control than spray application, coatings fortified with triglycine are more forgiving. Minor variations in brushing speed and overlapping strokes become far less noticeable, lowering the skill threshold required to achieve a premium look. It also suits DIY retail paint lines, professional on-site refurbishment and factory finishing workflows where visual consistency is a core quality metric.
Proper dosage control remains essential. Over-addition may overly soften the wet film and induce sagging on vertical surfaces, while insufficient loading limits its leveling effect. Formulators need to adjust the addition rate according to resin type, pigment volume concentration and target film thickness. It pairs well with standard defoamers and dispersants, simplifying reformulation for existing product lines.
FAQ
Does triglycine work for both brush and roller application?
Yes. It improves wet-film flow for brushes, rollers and low-pressure spray methods, though its most distinctive value lies in minimising visible brush traces from manual application.
Will triglycine affect the final hardness or adhesion of the cured coating?
When dosed within the recommended range, it has minimal negative impact on film hardness, substrate adhesion and long-term weather resistance. Formulation screening is still advised for high-performance exterior coatings.
Is triglycine compatible with water-based latex paints?
It shows excellent compatibility with most waterborne coating systems, making it suitable for eco-friendly low-VOC paint development alongside traditional solvent-based formulations.
Triglycine offers a fresh technical route for coating leveling. By regulating surface flow and smoothing out application-induced defects, it removes distracting brush marks while preserving critical coating properties. It serves as a flexible, formulator-friendly option for brands aiming to elevate surface appearance and deliver consistently high-quality finishes across both industrial and decorative coating portfolios.
