Manta S310 γ-Isocyanatopropyltrimethoxysilane

Manta S310 is a bifunctional organosilane possessing a highly active isocyanate group and a hydrolyzable trimethoxysilyl group. The isocyanate functionality exhibits the typical high reactivity of an alkyl isocyanate, reacting rapidly with most active hydrogen-containing compounds (such as hydroxyl, amino, and mercapto groups). The silane portion can then crosslink with each other upon moisture exposure or bond chemically to a wide variety of inorganic substrates.

It is the chemical equivalent to industry standards such as Momentive Silquest A-Link™ 35, WACKER GENIOSIL GF 40, and Shin-Etsu KBM-9007.

Properties

• Bifunctional Crosslinking: Highly reactive with -OH, -NH2, and -SH functional polymers, providing a highly efficient moisture-cure silane crosslinking mechanism.
• Rapid Cure Kinetics: The trimethoxy groups offer exceptionally fast hydrolysis and crosslinking in the presence of atmospheric moisture.
• Exceptional Adhesion: Acts as a premium adhesion promoter, providing superior wet and dry adhesion to difficult substrates including glass, metals, and inorganic minerals.
• Durable Bonds: The resulting siloxane bonds offer excellent thermal, chemical, and UV stability.

Manta S310 is widely utilized as an essential crosslinker, end-capper, and adhesion promoter across advanced polymer systems:

1. Polymer Modification (MS Polymer / SPUR): Functions as the critical end-capping agent for diols or polyol polymers to manufacture Silane-Modified Polymers (SMP) and SPUR (Silane Terminated Polyurethanes). This enables the creation of high-performance, one-part moisture-curable urethane adhesives, sealants, and coatings without the presence of free unreacted isocyanates.
2. Adhesion Promoter: Extensively used in silicone sealants, polyurethane paints, and hybrid adhesives requiring aggressively enhanced adhesion to organic plastics (like nylon) or inorganic substrates where active hydrogen species are present.
3. Resin Crosslinking: Serves as a highly efficient modifier for hydroxyl-bearing resins (such as Acrylic resins, PVA) and alkoxy-silyl crosslinked fluororesin fluids, dramatically improving their chemical resistance and weatherability.
4. Reactive Additive: Enhances the performance of one-part moisture-curable and two-part reactive polyurethane systems.
5. Automotive Glass Primers (AGR): A crucial component in the formulation of fast-curing polyurethane primers for Automotive Glass Replacement (AGR) and direct glazing, providing instantaneous and uncompromising adhesion to glass substrates.
