Areas of Application of BYK 333 CAS No. 4535-23563-4542

Coatings and Printing Inks

Features and Benefits

This additive drastically reduces the surface tension of coatings and printing inks, so it can improve substrate wetting and prevent shrinkage cavities. At the same time, it can improve the surface smoothness and gloss. Anti-blocking properties can be improved in aqueous systems.

Recommended Use

The adjuvant is recommended for all solvent-based, solvent-free and water-based coatings, printing inks, and varnishes.

Suggested dosage

0.05-0.3% auxiliary dosage (supply form) based on the total formulation, aqueous and uv systems can be added up to 1%.

The above recommended addition amount is for reference only, and the optimal addition amount needs to be determined through a series of experiments.

Addition method and processing guidance

The auxiliary agent can be added at any stage of production, including post-addition.

Special Reminder

Unlike ordinary silicone oils, the adjuvant is "user safe". However, before use, a series of tests should be passed to confirm whether the additive is foam stable, and its recoating properties and shrinkage tendency should also be evaluated.

Adhesives and sealants

Features and Benefits

BYK-333 is an efficient silicone surface additive. It can drastically reduce the surface tension, thus improving the wetting of the system on the surface of harsh substrates.

Recommended Use

It is particularly recommended for improving the wettability of polyurethane, epoxy and acrylate adhesives on substrates.

Suggested dosage

0.05-0.3% adjuvant dosage (form of supply) is based on total formulation.

The above recommended addition amount is for reference only, and the optimal addition amount needs to be determined through a series of experiments.

Addition method and processing guidance

The auxiliary agent can be added at any stage of production, including post-addition.

Special Reminder

Unlike ordinary silicone oils, the adjuvant is "user safe". However, before use, a series of tests should be passed to confirm whether the additive is foam stable, and its recoating properties and shrinkage tendency should also be evaluated.

Room temperature curing system

Features and Benefits

BYK-333 is an efficient silicone surface additive. It can drastically reduce the surface tension, thus improving the wetting of the system on the surface of harsh substrates.

Recommended Use

Particularly recommended for improving the substrate wettability of polyurethane and epoxy- based room temperature curing plastics.

Suggested dosage

0.05-0.3% adjuvant dosage (form of supply) is based on total formulation.

The above recommended addition amount is for reference only, and the optimal addition amount needs to be determined through a series of experiments.

Addition method and processing guidance

The auxiliary agent can be added at any stage of production, including post-addition. However, in order to reduce the foam stabilizing effect of the auxiliary agent, it is

recommended to add it at the final stage of manufacture.

Special Reminder

Unlike ordinary silicone oils, the adjuvant is "user safe". However, before use, a series of tests should be passed to confirm whether the additive is foam stable, and its recoating properties and shrinkage tendency should also be evaluated.
