BRB Sempure HV 6500 is a macro-emulsion of an optimized blend of medium and high viscosity polydimethylsiloxane oils stabilized with a non-ionic, nonylphenol-free surfactant system in water.
BRB Sempure HV 6500 exploits the complementary performance of two viscosity grades: the medium viscosity oil penetrates into the substrate providing remoistening and depth of image, while the high viscosity oil remains on the surface providing long-lasting gloss and protection.

BRB Sempure HV 6500 has a small particle size of less than 1 micron, which gives the emulsion outstanding stability and exceptional dilution properties with both tap water and demineralized water.
BRB Sempure HV 6500 has a neutral pH of 6.0 to 9.0 that prevents corrosion of processing machinery and is compatible with a wide range of formulation systems.

BRB Sempure HV 6500 is an SVHC-compliant product; levels of Cyclotetrasiloxane (D4), Cyclopentasiloxane (D5), and Cyclohexasiloxane (D6) are each below 0.1%, in compliance with REACH Regulation (EC) No 1907/2006 and EU restrictions on cyclic siloxanes.
BRB Sempure HV 6500 is also available as BRB Sempure HV 6500 LC, the low-cyclic variant, specifically introduced to meet increasing market demand for SVHC-compliant silicone emulsions.

Benefits or Advantages of BRB Sempure HV 6500:
BRB Sempure HV 6500 provides an optimized balance between ease of application, spreading, gloss retention, and durability through the unique dual-viscosity oil blend, which is not achievable with single-viscosity silicone emulsions.
BRB Sempure HV 6500 delivers excellent color enhancement and depth of image on treated surfaces, outperforming conventional single-grade PDMS emulsions in premium polish applications.

BRB Sempure HV 6500 offers outstanding resistance to heat with no thermal degradation, meaning it does not leave carbonaceous residues on surfaces exposed to elevated temperatures during processing or use.
BRB Sempure HV 6500 provides good lubricating power, slip characteristics, and detergent resistance, ensuring the protective layer persists through multiple cleaning cycles.

BRB Sempure HV 6500 contains a nonylphenol-free surfactant system, making it environmentally friendly and compliant with EU restrictions on alkylphenol ethoxylates in cleaning and maintenance products.
BRB Sempure HV 6500 has higher active silicone content at 60%, optimizing the cost of silicone per unit of finished formulation and reducing the volume of product required to achieve the target gloss and protection level.

BRB Sempure HV 6500 is ready to dilute with tap water for immediate use, or with demineralized water when the diluted emulsion requires extended storage stability.
BRB Sempure HV 6500 complies with SVHC requirements under REACH, with D4, D5, and D6 cyclic siloxane levels each below 0.1%, enabling use in products marketed in the European Union without SVHC labeling obligations.

Features of BRB Sempure HV 6500:
BRB Sempure HV 6500 is a milky white thin liquid at ambient temperature with a specific gravity of approximately 1.0 at 25°C and a pH of 6.0 to 9.0.
BRB Sempure HV 6500 contains 60% active polydimethylsiloxane blend and approximately 40% water with non-ionic emulsifiers, forming a macro-emulsion with a particle size below 1 micron.

BRB Sempure HV 6500 is chemically inert under normal conditions of use, does not react with most substrates, and is compatible with water-based formulation systems, detergents, and most common formulation ingredients.
BRB Sempure HV 6500 has good water repellent properties, providing hydrophobic protection to treated surfaces while remaining easy to apply and spread from the water-based emulsion form.

Chemical Properties of BRB Sempure HV 6500:
BRB Sempure HV 6500 is based on polydimethylsiloxane (PDMS), a silicon-containing polymer with the repeating unit -[Si(CH₃)₂O]n-, characterized by an alternating Si-O backbone with methyl groups attached to silicon atoms.
BRB Sempure HV 6500 combines PDMS oils of different kinematic viscosities in a single non-ionic aqueous emulsion, exploiting the well-known property that PDMS viscosity strongly influences surface behavior: lower viscosity PDMS spreads and penetrates, while higher viscosity PDMS remains on the surface and provides durability.

BRB Sempure HV 6500 is stable under recommended storage conditions and does not react dangerously under normal use conditions; PDMS is chemically inert toward most organic and inorganic compounds, dilute acids, and alkalis.
BRB Sempure HV 6500 may be destabilized by strong acids, strong alkalis, or organic solvents that disrupt the emulsion system, and concentrated D4 (octamethylcyclotetrasiloxane) present as a trace impurity is classified as Repr. 2 (H361f) and Aquatic Chronic 2 (H411).

Production of BRB Sempure HV 6500:
BRB Sempure HV 6500 is manufactured by BRB International B.V. through emulsification of a proprietary blend of medium and high viscosity trimethylsiloxy-terminated polydimethylsiloxane oils using a non-ionic, nonylphenol-free surfactant system to produce a stable macro-emulsion.
BRB Sempure HV 6500 production controls emulsification conditions, particle size distribution (target below 1 micron), active content, pH, and cyclic siloxane levels to ensure batch-to-batch consistency and SVHC compliance.

BRB Sempure HV 6500 is available from BRB International B.V. headquarters in Ittervoort, The Netherlands, and through a global distributor network; a Product Safety Data Sheet should be obtained from a BRB office prior to use.
