Diaminosilane 85% Solution | Manta A112T

Manta A112T is an 85%-active solution of N-β-(aminoethyl)-γ-aminopropyltrimethoxysilane (CAS 1760-24-3, amine value 13–15 mmol/g) used as an adhesion promoter and sizing agent in foundry resins, glass-fiber composites, sealants and 2K coatings. The reduced-viscosity 85% format disperses faster in high-viscosity resins and is comparable to Silquest A-1120 (85%) and DAMO-T.

Manta A112T is a high-performance, 85% active solution of diamino-functional silane (N-β-(aminoethyl)-γ-aminopropyltrimethoxysilane). It features two reactive amino groups and three hydrolyzable methoxysilyl groups.

Manta A112T ensures faster dispersion and more uniform distribution within polymer matrices and surface-treatment baths. It acts as an exceptional molecular bridge, bonding organic resins (epoxies, urethanes, phenolics) to inorganic substrates (glass, metals, minerals).

It is the direct performance equivalent to Silquest A-1120 (85%) and DAMO-T.

Features

1. Enhanced Dispersibility: The 85% concentration lowers the product’s viscosity, allowing for easier handling, more accurate dosing, and faster integration into high-viscosity resins.
2. Dual-Amine Power: Contains primary and secondary amines, providing stronger chemical bonding to organic polymers than mono-amino silanes.
3. Excellent Cost-Efficiency: Provides a high-performance adhesion solution optimized for large-scale industrial use in foundry and coating sectors.
4. Improved Wet Adhesion: Significantly boosts the resistance of cured systems to water, humidity, and chemical exposure.

Manta A112T is a high-performance, multi-functional additive engineered for a broad spectrum of industrial applications where superior adhesion and rapid resin integration are critical:

1. Foundry Resins (Cold-Box & Hot-Box)

As a premier additive to various foundry resins (such as Phenolic, Furan, and Urethane systems), Manta A112T significantly boosts the mechanical strength of the sand core. Its optimized viscosity allows for uniform distribution during high-speed mixing, leading to higher humidity resistance and improved surface finish of the castings.

2. Glass Fiber & Mineral-Filled Composites

Functions as a high-efficiency sizing agent or finish constituent for glass fibers, glass fabrics, and mineral wool. It provides an excellent molecular bridge between the inorganic surface and the polymer matrix (Epoxy, Phenolic, etc.), drastically improving wet/dry mechanical properties and preventing fiber-matrix de-bonding.

3. Sealants & Adhesives (RTV & Hybrid)

Acts as a powerful internal adhesion promoter and primer for RTV silicones, two-part polyurethanes, and MS/SPUR hybrid sealants. It is particularly effective for achieving robust adhesion to difficult-to-bond substrates such as aluminum, stainless steel, and various engineering plastics without the need for additional primers.

4. Paints & Coatings (Industrial & Heavy-Duty)

Used as an additive or primer in 2K epoxy and polyurethane coatings. Manta A112T enhances inter-coat adhesion and increases the resistance of the coating film to water, salt spray, and chemical corrosion. Its 85% active format ensures seamless incorporation into solvent-borne and high-solids coating systems.

5. Mineral-Filled Polymers

Specifically designed for the pretreatment of inorganic fillers (such as Silica, Wollastonite, Mica, and Talc) or pigments. It improves the dispersibility of fillers within the polymer melt, resulting in composites with higher impact strength, improved processability, and superior electrical properties.

6. Metal Surface Pre-treatment

Utilized in the formulation of metal primers and conversion coatings. It creates a dense, hydrophobic siloxane layer on metal surfaces (Steel, Zinc, Aluminum), providing a reactive base that significantly anchors subsequent paint layers and improves long-term anti-corrosion performance.

7. Resin Modification

Highly effective for the chemical modification of phenolic, melamine, and epoxy resins. By integrating into the resin backbone, it enhances the thermal stability and moisture resistance of the final cured products used in laminates and friction materials.
