Features of LS-A112T (2-Aminoethyl)-3-aminopropyltrimethoxysilane (Technical Grade)
1. Advanced Bis-Silane Synergy: The strategically retained 15% oligomeric fraction (heavy ends) functions as built-in bis-silane crosslinkers. This generates a significantly denser, more robust 3D siloxane network at the interface compared to the 100% pure monomer.
2. Superior Wet Adhesion & Hydrolysis Resistance: The optimized oligomeric content drastically boosts the resistance of cured polymer systems to boiling water, high humidity, and aggressive chemical exposure.
3. Dual-Amine Reactivity: Contains both primary and secondary amines, providing incredibly fast reaction kinetics and exceptionally strong covalent bonding to challenging organic matrices (epoxies, phenolics).
4. Extreme Cost-Efficiency: Delivers uncompromising interfacial adhesion and mechanical reinforcement at a highly optimized price point, perfectly tailored for high-volume consumption in foundry core binders and mineral treatments.
Applications of LS-A112T (2-Aminoethyl)-3-aminopropyltrimethoxysilane (Technical Grade)
Silfluo LS-A112T is a multi-functional additive engineered for industrial applications where superior adhesion, rapid resin integration, and cost-efficiency are critical:
1. High-Performance Foundry Resins (Cold-Box & Hot-Box): Serves as the premier adhesion promoter for foundry binders (Phenolic, Furan, and Urethane systems). It significantly boosts the tensile strength of the sand core, improves humidity resistance during storage, and ensures a flawless surface finish for cast metal parts.
2. Heavy-Duty Paints & Industrial Coatings: Used as a critical additive or primer component in 2K epoxy and polyurethane anti-corrosion coatings. The bis-silane content enhances inter-coat adhesion and maximizes the coating film's resistance to prolonged salt spray and chemical corrosion.
3. Glass Fiber & Mineral-Filled Composites: Functions as a high-efficiency sizing agent for glass fibers, glass fabrics, and mineral wool. It provides an excellent molecular bridge between the inorganic surface and the polymer matrix, preventing catastrophic fiber-matrix de-bonding under high stress.
4. Sealants & Structural Adhesives: Acts as a powerful internal adhesion promoter for two-part polyurethanes and hybrid sealants, achieving robust, unprimed adhesion to difficult substrates such as aluminum, stainless steel, and engineering plastics.
5. Mineral Filler Pretreatment: Specifically designed for treating inorganic fillers (Silica, Wollastonite, Mica, Talc). It improves filler dispersibility within the polymer melt, resulting in composites with superior impact strength and processability.
