Characteristics, Applications, and Usage Recommendations of BYK 358N

BYK 358N is a surface additive based on polyacrylate, primarily used to improve the leveling and anti-pinhole performance of systems such as solvent-based coatings, printing inks, room-temperature curing plastic systems, unsaturated polyester resins, and epoxy resins.

Properties of BYK 358N

Improved leveling performance

BYK 358N effectively enhances the leveling of coatings, resulting in a smoother and more uniform surface.

Anti-pinhole performance

BYK 358N provides excellent anti-pinhole properties, preventing defects such as pinholes during the drying process.

Increased gloss

The use of BYK 358N increases the gloss of the coating and produces a long-wave effect.

No effect on re-coating

BYK 358N does not negatively impact the re-coatability or interlayer adhesion of the coating.

Thermal stability

BYK 358N exhibits thermal stability, making it suitable for medium to high polarity systems.

Applications of BYK 358N

Solvent-based coating systems

Such as automotive coatings and industrial coatings, where it is used to improve leveling and anti-pinhole properties.

Printing inks

To enhance the flow and spreading properties of the ink, improving print quality.

Room-temperature curing plastic systems

Such as polyurethane and epoxy resins, where it helps improve the smoothness and gloss of the coatings.

Unsaturated polyester resins and epoxy resins

To enhance the leveling and anti-pinhole properties of these resin systems.

Recommended Use of BYK 358N

Additive concentration

Based on the total formulation, the recommended dosage of BYK 358N is 0.11% (for solvent-based coatings, printing inks, varnishes, color coatings) and 0.10-0.5% (for room-temperature curing plastic systems, unsaturated polyester resins, and epoxy resins). The specific dosage should be adjusted based on the actual application system and process conditions.

Addition method

BYK 358N can be added at any stage of the production process, including post-addition. To ensure uniform dispersion of the additive in the system, it is recommended to mix using appropriate shear force.

Storage conditions

BYK 358N should be stored in a cool, dry, and well-ventilated area, protected from direct sunlight and high temperatures.
