Deuteron ST500

Deuteron ST 50, ST 100, ST 125, ST 250, and ST 500 are thermoplastic texturing agents designed to create distinct surface structures. Here's a breakdown of their characteristics:

• Material: Each variant is composed of different materials:
  • ST 50 and ST 100: HDPE (High-Density Polyethylene)
  • ST 125: Polyamid
  • ST 250 and ST 500: Polyester
• Particle Size:
  • dv50 (median particle size): Varies from approximately 60 μm to 320 μm, depending on the variant.
  • dv90 (90th percentile particle size): Varies from approximately 100 μm to 1000 μm.
• Density: Varies among the variants, ranging from approximately 0.96 g/cm³ to 1.28 g/cm³.
• Melting Range: Between 126-130 °C for ST 50 and ST 100, and 150-160 °C for ST 125, ST 250, and ST 500.
• Appearance: Coarse white powder.

These texturing agents are utilized to introduce texture and structure to surfaces for functional, haptic, and decorative effects. The final texture achieved depends on factors such as layer thickness and the ratio of texturing agent to binder. Different dosages can result in effects ranging from a rough, fragmented structure with minimal impact on gloss to matte surfaces with closed particle layers.

Key applications of Deuteron ST texturing agents include coatings and inks, where they enhance properties like mechanical and chemical resistance, roughness, and blocking resistance. They are compatible with solvent-based, solvent-free, and water-based systems, and can be combined with other surface additives such as matting agents or waxes.

Dosage recommendations typically range from 1% to 15% of the complete formulation, depending on the binder, application, and desired properties. The optimal dosage is determined through testing and is influenced by factors like the ratio of binder solids to texture agent and layer thickness.

Processing these thermoplastic texturing agents is straightforward and usually does not require high shear forces or wetting agents. They are shear-stable, but grinding should be avoided.

Deuteron ST products have a shelf life of 24 months under room temperature and dry conditions. While they are not classified as dangerous products according to regulations, proper handling procedures should be followed.

Overall, Deuteron ST texturing agents offer a versatile solution for creating surface textures in various coating and ink applications, providing enhancements in both aesthetics and performance.
