Deuteron ST250

Deuteron ST 250 is a thermoplastic texturing agent produced by Deuteron GmbH. Here's an overview of its key characteristics:

• Material: Deuteron ST 250 is made of polyester.
• Particle Size: It has a particle size distribution with a dv50 (median particle size) of approximately 320 µm and a dv90 (90th percentile particle size) of approximately 460 µm.
• Density: The approximate density of Deuteron ST 250 is around 1.28 g/cm³.
• Melting Range: Its melting range falls within 150-160 °C.
• Appearance: Deuteron ST 250 appears as a coarse white powder.

Product Description: Deuteron ST 250 is formulated as a coarse plastic powder utilized for creating distinct surface structures. It functions as a texture and structuring agent, imparting functional, haptic, and decorative effects to surfaces. Similar to other products in the Deuteron ST series, the final appearance of the textured surface depends on factors such as applied layer thickness and the ratio of texturing agent to binder. It offers versatility, enabling the creation of effects ranging from rough, fragmentary structures to closed particle layers with matte surfaces.

Applications: Deuteron ST 250 finds application across various coatings and inks. Its particle size distribution allows for precise adjustments of surface appearance and roughness. Additionally, it can be combined with other surface additives like matting agents or waxes. It is compatible with solvent-based, solvent-free, and water-based systems.

Dosage: The recommended dosage of Deuteron ST 250 typically ranges from 1% to 15% of the complete formulation, depending on factors such as binder type, application method, and desired properties. Determination of the optimal dosage should involve testing and consider variables such as binder solids ratio and layer thickness.

Processing: Deuteron ST 250 is generally straightforward to use and usually does not necessitate high shear forces or wetting agents during processing. However, grinding should be avoided.

Storage Conditions: For optimal storage, Deuteron ST 250 should be kept in dry conditions at room temperature for up to 24 months. The storage temperature should not exceed 35°C.

Safety: In accordance with Regulation (EC) No. 1272/2008, Deuteron ST 250 is not classified as a dangerous product and does not require specific labeling. Nonetheless, it's prudent to consult the Safety Data Sheet and Regulatory Information Sheet for comprehensive safety information.
