Typical materialized data

The data given on this data sheet are only typical values, not the technical specifications of the product.
 

storage and transportation

Layering or turbidity may occur below 5 °C, heat to 20 °C and mix well.

Room temperature curing plastic system

Features and Benefits: BYK-306 is a highly effective silicone additive that significantly reduces surface tension, thereby improving wetting on difficult-to-wet substrates. When used in pigment filled systems
Prevents Bernard vortex and improves leveling.

  Recommended Applications  

BYK-306 is recommended for polyurethane and epoxy systems.

Recommended dosage

0.1-0.5 % Auxiliary dosage (as purchased) based on total formulation

The above data are empirical dosages, and the optimal dosage needs to be determined through a series of experiments.

Incorporation Method and Processing Instructions

The adjuvant can be added at any stage in the production process and can also be added later.
The adjuvant can be added at the last stage of production to avoid foam stabilization, which has proven to be very effective.

  pay attention  

Compared with silicone oil, the additive is safe to use. However, it should still be tested whether surface defects will occur in the corresponding system before extensive use.

paint industry

Features and Benefits: This silicone additive significantly reduces the surface tension of the coating system and can effectively wet hard-to-wet substrates. BYK-306 improves acceptance of dust and paint mist and increases surface slip. The additive reduces the sensitivity of wood and furniture coatings to drafts and improves the orientation of matting powders.

  Recommended Applications  

The additive can be used in all solvent-borne systems.

Recommended dosage

0.1-0.5 % Auxiliary dosage (as purchased) based on total formulation

The above data are empirical dosages, and the optimal dosage needs to be determined through a series of experiments.

Incorporation Method and Processing Instructions

The adjuvant can be added at any stage in the production process and can also be added later. For ease of metering, the adjuvant can be pre-diluted.

  pay attention  

Compared with silicone oil, the additive is safe to use. However, the foam stability, recoatability and crater tendency in the corresponding system should still be tested before extensive use.
