Momentive Tospearl 3000A Silicone Microsphere

Momentive Tospearl 3000A Silicone Microspheres are hydrophobic, spherical polydimethylsiloxane particles designed for texture enhancement, slip improvement, and matte finish in cosmetics and personal care formulations. Their uniform particle size (~30 µm) ensures consistent sensory performance, oil absorption control, and reduced tackiness without compromising spreadability or stability.

Features Of Momentive Tospearl 3000A Silicone Microsphere

  1. Uniform spherical morphology ensures consistent optical diffusion and surface texture control.

  2. Highly crosslinked polydimethylsiloxane (PDMS) structure delivers excellent thermal and chemical stability.

  3. Low density and high compressibility enable efficient suspension in solvent-based and high-solids coatings.

  4. Non-migrating, non-blooming formulation maintains long-term clarity and performance in transparent systems.

  5. Reproducible particle size distribution (D50 ≈ 30–40 µm) supports precise rheology and film-building behavior.

Typical Applications Of Momentive Tospearl 3000A Silicone Microsphere

  1. Architectural and industrial topcoats requiring matte finish and anti-blocking properties.

  2. Automotive clearcoats for controlled haze reduction and enhanced scratch resistance.

  3. UV-curable inks and coatings where low VOC and substrate compatibility are critical.

  4. Plastic coatings and overmolded polymer surfaces seeking soft-touch feel and fingerprint resistance.
