Product Description
Manta L1231 is a monomeric long-chain alkyl functional silane, chemically identified as n-dodecyltrimethoxysilane. Featuring a 12-carbon (C12) linear alkyl chain, this product delivers exceptional hydrophobicity and outstanding weather resistance (UV stability).
Compared to shorter-chain silanes (e.g., C8 or C10), its heavier molecular structure significantly reduces volatility and provides a moderate, highly controlled penetration depth. This makes Manta L1231 exceptionally ideal for treating highly sensitive substrates and achieving premium, long-lasting surface modification without altering the natural breathability or aesthetics.
Chemically equivalent to Wacker GENIOSIL® DD-Trimethoxy, and serves as a long-chain functional upgrade to C10 silanes such as Shin-Etsu KBM-3103.
Applications
Manta L1231 is highly versatile and serves as a premium water repellent and interface modifier across a wide spectrum of industries:
- Cultural Heritage Conservation (Specialty Use): > Due to its extremely low volatility, controlled penetration, and durable hydrophobic network, it is highly recommended for the protection and restoration of historical monuments, artifacts, and highly sensitive porous masonry.
- Natural Stone & Concrete Protection: > Provides deep, long-lasting water repellency for premium natural stone, masonry, and concrete while retaining 100% water vapor permeability and the original appearance of the substrate.
- Surface Modification of Mineral Fillers: Significantly improves the dispersibility, compatibility, and hydrophobicity of inorganic fillers and pigments in non-polar plastics, rubbers, and resin matrices.
- Coatings, Adhesives & Sealants: Acts as a performance-enhancing additive to dramatically improve moisture resistance and interfacial adhesion.
- Mold Release Applications: Effectively functions as a semi-permanent release agent in various molding processes due to the strong non-polar nature and low surface energy of its long C12 alkyl chain.
Application Areas
Packaging & Handling
Packaging
In 20kg pail, 180kg drum and 900kg IBC
Safety and Storage
Highly Reactive & Methanol Release: Manta L1231 reacts with water and atmospheric moisture to form cross-linked polysiloxanes. CRITICAL WARNING: This hydrolysis reaction releases METHANOL as a toxic and highly flammable byproduct. Strictly ensure excellent local exhaust ventilation during formulation, application, and curing to prevent vapor accumulation.
Storage Conditions: Store in a cool, dry, and well-ventilated area strictly away from open flames and moisture. Keep containers hermetically sealed at all times to prevent premature moisture cross-linking.
Shelf life is 12 months. It is non-hazardous substance.
