Auxiliary Driers

Quick Access

Calcium Carboxylate

Calcium series are auxiliary driers which are combined with the primary and through driers to promote a balanced drying profile, prevent haze and wrinkling and have no adverse effects on the gel strength of thixotropic paints.

Calcium carboxylates are of two technology: (i) overbased, and (ii) neutral;

Overbased calcium carboxylate reaches higher metal percentages than neutral calcium carboxylate.
Neutral calcium carboxylates are less sensitive to humid environments in terms of their nature and, neutral calcium carboxylates can be used in high humidity applications.

By adding EGEDry® & Durham Nuodex Calcium carboxylates at the mill-base stage, they can be used as supportive agent for a better wetting and dispersing.

EGEDry® & Durham Nuodex Calcium carboxylates at the mill-base stage when using highly active pigments such as blacks, deep reds and blues they act as sacrificial driers to reduce the absorption of Cobalt and zirconium driers.

EGEDry® & Durham Nuodex Calcium series are low viscosity, colourless to pale yellow Calcium carboxylate driers for coatings, based on saturated branched synthetic acids in hydrocarbon solvents suited for the end users’ needs.

Barium Carboxylate

EGEDry® & Durham Nuodex Barium series are low viscosity, colourless to pale yellow coloured barium carboxylates driers for coatings, based on saturated branched synthetic acids in hydrocarbon solvents suited for the end users’ needs.

Barium carboxylates are auxiliary modifier driers which work with the primary and through driers.

Barium carboxylates can be used to significantly increase the gloss of a coating.

Barium carboxylates can exhibit good thermal stability, making them suitable for high-temperature applications.

Products Metal Concentration(%) Nature Solvent Recommended Dosage (%)
EGEDry® Barium Oct 12.5 2–Ethylhexanoic acid D60, WS 0,1 – 0,3
EGEDry® Barium Neo 12.5 Neodecanoic acid D60, WS 0,1 – 0,3
Durham Nuodex Barium 12.5 2-Ethylhexanoic acid D60 0,1 – 0,3
Durham Nuodex Barium Neo 12.5 Neodecanoic acid D60 0,1 – 0,3

Zinc Carboxylate

EGEDry® & Durham Nuodex Zinc series are low viscosity, colourless to pale yellow Zinc carboxylates driers for coatings, based on saturated branched synthetic acids in hydrocarbon solvents suited for the end users’ needs. Additionally, HARCAT Zinc 22 a solvent-free zinc carboxylate product with high zinc content is also included in this group.

Zinc carboxylates have a wide range of applications due to their diverse properties.

Zinc carboxylates can improve drying and hardening as an auxiliary drier in paints and coatings.

Products Metal Concentration(%) Nature Solvent Recommended Dosage (%)
EGEDry® Zinc Oct 16–12–10–8 2–Ethylhexanoic acid D60, WS, TOL 0,1 – 0,3

Durham Nuodex Zinc Neo 18–16–12–10–8 Neodecanoic acid D60 0,1 – 0,3
Harcat Zinc 22 2–Ethylhexanoic acid Solvent Free 0,1 – 0,3

Lithium Carboxylate

EGEDry® & Durham Nuodex Lithium neodecanoate is low viscosity, colourless to pale yellow Lithium carboxylate driers for coatings, based on saturated branched synthetic acids in hydrocarbon solvents suited for the end users’ needs.

EGEDry® & Durham Nuodex Lithium neodecanoate is a through paint drier.

EGEDry® & Durham Nuodex Lithium neodecanoate is effective for through dry at the low temperature paint applicaitons.

EGEDry® & Durham Nuodex Lithium neodecanoate can be used in water based coatings to promote through dry and to enhance the miscibility of the primary drier.

Products Metal Concentration(%) Nature Solvent Recommended Dosage (%)
EGEDry® Lithium Neo 2 Neodecanoic acid D60, WS 0,1 – 0,2
Durham Nuodex Lithium 2 Neodecanoic acid D60 0,1 – 0,2

Storage

It should be stored in cool and dry places below 30°C. Since it is a product that oxidizes easily, packages should not be open during storage. Shelf life is 60 months from the production date.
