Application Information

Coatings industry
Special features and benefits

The additive improves the scratch resistance in aqueous coatings; it increases the abrasion resistance in printing inks in particular. Surface slip and block resistance are also improved.

Recommended levels
2–5% additive (as supplied) based upon total formulation.
The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.
Incorporation and processing instructions
The additive is preferably incorporated into the coating with a low shear rate at the end of the production process. Stir well before use.

 

Adhesives and sealants
Special features and benefits

Aquacer® 531 is used as an anti-blocking additive in the manufacture of hot-melt adhesives during underwater pelletizing to obtain free-flowing and non-sticking granulated material. It is directly added to the cooling water and, therefore, is easy to handle and dust-free.
Recommended levels
0.5–5% additive (as supplied) based upon amount of water in the cooling circuit.
The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.
Incorporation and processing instructions
The additive is added directly to the circuit water. If foaming occurs in the circuit water, we recommend defoamers BYK-023 or BYK-016 at a dosage of 0.05–0.3%.

Thermoplastics
Special features and benefits

Thermoplastic granulated material (TPE, TPU, EVA) tends to compact and cake under pressure and heat. Aquacer® 531 is used in the underwater pelletizing of such materials and forms a protective layer covering the granules, thereby generating non-sticking and free-flowing granulated materials. Unlike the commonly performed dusting of the granulate materials with solid release agents (chalk, talc), significantly lower quantities are needed, which, therefore, avoid an impact on the properties of the thermoplastic material.
The generation of dust during processing is also eliminated. If foaming occurs in the circuit water during underwater granulation, we recommend defoamers BYK-023 (silicone defoamer) at a dosage of 0.05–0.1%.
Recommended levels
0.2–5% additive (as supplied) in the circuit water.
The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.
Incorporation and processing instructions
The additive is added directly to the circuit water.

 

Lubricants and metal processing
Special features and benefits

Aquacer® 531 is used in dry lubricants and anti-friction coatings to adjust the coefficient of friction (CoF). On most metallic substrates it forms a uniform wax layer, which results in a low CoF. The product can be used to achieve a CoF of between 0.1 and 0.15. It can be used by itself or in combination with other aqueous binders, such as silicates or acrylates. It is frequently used in dry lubricants and anti-friction coatings for fasteners such as screws and nuts, and in surface sealers for metal components.
Recommended levels
2–10% wax content based on the total formulation.
The above recommended levels can be used for orientation.The optimum dosage should be determined by application-related test series.
Incorporation and processing instructions
The additive can be incorporated at any point during formulation.
