SYLOWHITE SM 405 is commonly represented by the formula AlMgNaO₉Si₃ and has a calculated molecular weight of approximately 302.53 g/mol.
SYLOWHITE SM 405, this formula should be understood as a compositional representation of the registered silicate substance rather than as a conventional discrete molecular structure.
This distinction is relevant when comparing the product with crystalline aluminosilicates, zeolites or other defined inorganic compounds.
SYLOWHITE SM 405 is produced as a precipitated amorphous silicate with a very fine particle size and a white free-flowing appearance.
SYLOWHITE SM 405 information describes the particle size as less than 6.0 µm, while the controlled particle-size distribution and pore structure are important to its performance as a titanium dioxide extender.
The fine powder morphology allows the material to interact effectively with pigment particles and supports uniform dispersion in suitable coating systems.
SYLOWHITE SM 405 is not primarily used as the main white pigment.
SYLOWHITE SM 405s function is to extend and improve the efficiency of titanium dioxide by promoting a more homogeneous distribution of TiO₂ particles within the coating.
This approach can allow formulators to reduce the amount of titanium dioxide required while maintaining the targeted optical performance of the finished coating.
SYLOWHITE SM 405 contributes to its performance in pigment-containing formulations.
The material can improve the spacing and distribution of titanium dioxide particles, which is particularly important because pigment crowding can reduce the efficiency of light scattering.
A more efficient distribution of TiO₂ can therefore support opacity and brightness while providing an opportunity for raw-material cost optimization.
SYLOWHITE SM 405 is characterized by high purity and fine whiteness, making it suitable for formulations where the extender should have minimal adverse influence on the final color.
SYLOWHITE SM 405 is also described as easy to disperse in paint systems, which is important for both industrial production and decorative coating manufacture.
The combination of whiteness, particle-size control and dispersion behavior gives the material a practical role in modern coating formulations.
SYLOWHITE SM 405 is intended for high-quality waterborne and solvent-borne coating systems.
Typical applications include interior and exterior trade paints, do-it-yourself paints, industrial coatings and printing inks.
SYLOWHITE SM 405s use is therefore not limited to a single coating technology and can be evaluated in different binder and pigment systems according to the requirements of the finished product.

SYLOWHITE SM 405 can be used as part of a formulation strategy for maintaining opacity and whiteness while reducing reliance on titanium dioxide.
The product is particularly relevant where the formulator is balancing pigment cost, hiding performance and the visual appearance of the finished paint.
SYLOWHITE SM 405s use can also support formulation continuity when titanium dioxide availability or pricing becomes a significant consideration.
Industrial coatings represent another important application area for SYLOWHITE SM 405.
In these systems, particle distribution, coating appearance and formulation economics must be considered together rather than evaluating the extender only on the basis of its filler content.
The fine precipitated silicate structure provides a functional alternative to conventional inert extenders when optical efficiency is an important formulation target.
SYLOWHITE SM 405 is also suitable for printing ink applications.
SYLOWHITE SM 405s fine particle size, whiteness and ability to support pigment distribution make it relevant to formulations where optical appearance and controlled pigment performance are important.
SYLOWHITE SM 405 has been commercially identified for use as a raw material in printing ink manufacture as well as in paint systems.
SYLOWHITE SM 405 is its ability to function as a titanium dioxide extender rather than simply acting as a conventional mineral filler.
Grace product information indicates that optimized formulations can achieve titanium dioxide reductions of up to approximately 20% by weight while maintaining the desired coating performance.
The actual replacement level depends on the binder system, pigment concentration, dispersion conditions and optical requirements of the individual formulation, so formulation testing remains necessary before setting a production level.
SYLOWHITE SM 405 can contribute to improved whiteness and optimized opacity when incorporated into appropriately designed coating systems.
SYLOWHITE SM 405 is also associated with reduced yellowing of paint during aging and favorable application characteristics.
These properties make SYLOWHITE SM 405 relevant to formulators seeking a balance between optical performance, titanium dioxide efficiency and raw-material cost.
The physical form of SYLOWHITE SM 405 is particularly important during processing.
As a finely divided powder, it can generate dust during weighing, transfer and incorporation into a formulation, so controlled powder handling and suitable local ventilation should be considered.
SYLOWHITE SM 405 should also be protected from contamination and unnecessary exposure to moisture during storage and handling.
SYLOWHITE SM 405 should be stored in a dry warehouse under conditions that prevent contamination and moisture uptake.
Opened packages should be properly resealed because the product can adsorb water or other gases and vapors from the surrounding environment.
SYLOWHITE SM 405 information indicates a recommended use period of up to 12 months from production for bulk or big-bag material and up to 24 months for material supplied in bags, subject to the applicable product documentation.
SYLOWHITE SM 405 should also take electrostatic discharge into account.
Appropriate precautions during powder transfer and processing help reduce operational risks associated with dust and electrostatic charge accumulation.
The current Safety Data Sheet should always be used for the specific grade and supply lot when defining workplace controls and personal protective equipment.
SYLOWHITE SM 405 is distinct from crystalline silica and should not be described simply as conventional crystalline silica.
Available product information identifies the material as a precipitated amorphous sodium magnesium aluminium silicate, and the manufacturer documentation specifically distinguishes its amorphous silicate character.
This distinction is important when assessing the material for coating formulations, workplace handling and regulatory documentation.
From a formulation perspective, the most relevant parameters when evaluating SYLOWHITE SM 405 are particle-size distribution, dispersion behavior, whiteness, pigment interaction and the effect on coating opacity.
The appropriate addition level cannot be determined from the CAS identity alone because the final performance depends strongly on the binder, pigment volume concentration, dispersant package and processing conditions.
For this reason, laboratory drawdowns and comparative TiO₂ optimization trials are recommended before transferring a formulation to industrial production.
SYLOWHITE SM 405 can be considered when a coating manufacturer wants to improve titanium dioxide utilization without changing the overall visual character of the finished product.
Its role is particularly valuable in formulations where opacity, whiteness, pigment distribution and material cost must be optimized simultaneously.
The product therefore serves as a functional extender for coatings and inks rather than as a simple volume-building filler.
SYLOWHITE SM 405 is supplied as a white, free-flowing precipitated silicate powder for industrial formulation applications.
Published packaging information includes 25 kg bags as well as big-bag and bulk supply formats, although the exact packaging configuration should be confirmed for the material being purchased.
Technical documentation and current supplier specifications should be reviewed before selecting the product for a specific production process.
