• TEGO®Powder Aid D01 reduces the melt viscosity of powder coating formulations
• Helps powder coatings improve the gloss and freshness of the paint film
• Versatile for high PVC (Pigment Volume Concentration) systems
Evonik presents TEGO®Powder Aid D01
, a new multifunctional polymer additive for powder coating formulations.
This product makes formulations more dispersible during extrusion, promotes pigment wetting and effectively reduces melt viscosity
TEGO®Powder Aid D01 has a low melt tack, which promotes degassing, aids flow and leveling of the formulation as it cures, and prevents pinholes
in the coating.
As a result, the new additive improves the gloss of the coating and ensures a higher freshness (DOI)
on the coated surface.
Another significant advantage of TEGO®Powder Aid D01 is its wide range of applications for the formulation
of inorganic fillers and inorganic pigments as well as organic pigments such as carbon black.
Maximilian Morin, Head of Marketing for Industrial and Transportation Coatings in the Coatings Additives business line at Evonik, says: "Formulators often need a versatile additive for a wide range of powder coating systems, and this new product from Evonik meets this need
TEGO®Powder Aid D01 produces significant results in very small amounts and works synergistically with other additives
Reduced melt viscosity
Powder coatings for HAA curing systems generate water as a by-product during the curing process: during crosslinking, water molecules escape from the system, resulting in pinholes or shrinkage holes in the film
This is a major problem
for HAA system powder coatings.
The low melt viscosity helps to improve the dispersion uniformity of the various raw materials in the coating and improve the leveling of the film-forming surface, thus avoiding this situation
TEGO®Powder Aid D01 prevents pinholes by increasing the degassing limit value, even with
Durable and recoatable
Powder coatings with TEGO®Powder Aid D01 are also weather-resistant, suitable for outdoor applications and do not yellowing due to high-temperature baking
The new additive also does not contain surface-active waxes and therefore has good recoating properties
A new addition to Evonik's coating additives portfolio, TEGO®Powder Aid D01 can be added to the extrusion stage of powder coatings to significantly optimize powder coating formulations
