Hexadecyltrimethoxysilane (C16) | Manta L1631

Manta L1631 is hexadecyltrimethoxysilane (CAS 16415-12-6, ≥95.0% GC purity), a C16 alkyl silane used to treat ATH, MDH and other mineral fillers for HFFR cable compounds, disperse pigments, protect glass fiber, and serve as the active base for silane creams. Comparable to Evonik Dynasylan 9116 and Wacker GENIOSIL HDTM-T, its low volatility extends substrate dwell time.

Manta L1631 is a monomeric long-chain alkylfunctional silane, chemically identified as n-hexadecyltrimethoxysilane. Featuring an exceptionally long 16-carbon (C16) linear alkyl chain, this silane exhibits profound hydrophobicity and outstanding lipophilicity (affinity for non-polar matrices).

Due to its highly non-polar C16 structure, Manta L1631 drastically reduces the surface energy of treated substrates. This makes it an elite surface modifier for inorganic fillers, pigments, and glass fibers, ensuring perfect dispersion and compatibility within non-polar polymer matrices (such as polyolefins).

Meanwhile, its highly reactive methoxy groups ensure rapid hydrolysis and efficient chemical bonding to inorganic surfaces. Furthermore, its high molecular weight translates to extremely low volatility, high thermal stability, and long-lasting performance even under demanding processing conditions.

1. Premium Surface Modifier for Mineral Fillers (Plastics & HFFR Cables)

Acts as a highly efficient surface treatment agent for inorganic flame retardants, such as ATH (Aluminum Trihydroxide) and MDH (Magnesium Dihydroxide).

Significantly improves the dispersion and compatibility of highly loaded fillers within non-polar polymer matrices (e.g., PE, PP, EVA).

Widely used in the production of Halogen-Free Flame Retardant (HFFR) cables, enhancing melt flow processability, reducing compound viscosity, and preserving the mechanical properties of the final product.

2. Active Ingredient for Silane Creams & Emulsions (Concrete Protection)

Serves as an excellent active base material for formulating high-end, VOC-compliant silane creams/gels and water-based water repellent emulsions.

Due to its exceptionally low volatility and slow evaporation rate, it ensures a longer dwell time on the substrate surface, allowing for deeper penetration into high-density concrete and infrastructure without significant evaporation loss.

3. Pigment Dispersion & Color Masterbatches

Dramatically lowers the surface energy of inorganic pigments (such as titanium dioxide and iron oxides), facilitating rapid wetting and superior dispersion in non-polar media.

Helps formulators achieve higher pigment loading, lower processing viscosity, and enhanced color strength.

4. Treatment for Glass Fibers & Mineral Wool

Imparts excellent, long-lasting water resistance to glass fibers and mineral wool.

Improves the resin wet-out process and enhances interfacial adhesion between the inorganic fibers and organic resin matrices.
