Our new multifunctional TEGO® Powder Aid D01 makes powder coating formulations easier to disperse during extrusion by promoting pigment wetting and effectively reducing melt viscosity. Learn more about its benefits by watching the video.
New additive TEGO® Powder Aid D01 improves powder coating formulations in many ways
Evonik Coating Additives has developed a new, multifunctional polymer additive for powder coating formulations: TEGO® Powder Aid D01 enhances dispersion during extrusion by promoting pigment and filler wetting, and effectively reducing melt viscosity.
Temperature sweep: Reduced melt viscosity with TEGO® Powder Aid D01The lower melt viscosity also leads to better degassing, which aids flow and leveling as the formulation cures and prevents pinholes in the coating. Thus, the new additive optimizes gloss development and ensures better DOI (distinctness of image) on the coating surface.

Another advantage of TEGO® Powder Aid D01 is its versatility. It can be used in formulations containing inorganic fillers and pigments, as well as organic pigments including carbon black. Our new product therefore offers a wide range of benefits for formulators who prefer one multifunctional additive for various powder coating systems. TEGO® Powder Aid D01 generates a large effect at small use-levels and acts as a synergist with other additives.
Durable, recoatable coatings
Powder coatings containing TEGO® Powder Aid D01 also show comparable resistance to weathering, making this additive suitable for use in exterior applications. So-called overbake yellowing, even at elevated temperatures, is manageable. The new additive imparts these positive properties to powder coating formulations without containing surface-active waxes. As a result, overcoating is also possible without any problems.
TEGO® Powder Aid D01 - New additive for powder coating formulations!
Formulating powder coatings with high pigment volume concentrations can be a challenge. Accomplish your goals with the help of TEGO® Powder Aid D01.
TEGO® Powder Aid D01 at a glanceTEGO® Powder Aid D01 is a multifunctional polymeric additive, consisting of 100% active matter pellets, for powder coatings.
TEGO® Powder Aid D01 improves pigment wetting and provides better dispersion during extrusion. It contributes significantly to an increase in gloss and DOI. The new additive imparts these positive properties to powder coating formulations without containing surface-active waxes. As a result, formulators will not encounter problems with overcoating.
When added to powder coating formulations, this additive has the complimentary benefit of reducing melt viscosity which leads to improved degassing effect.
