Tris(trimethoxysilylmethyl) Isocyanurate | Manta AM311

Manta AM311 is 1,3,5-tris(trimethoxysilylmethyl)isocyanurate (CAS 82199-95-9, ≥95% purity by GC), an alpha-functional isocyanurate silane used as a crosslinker and adhesion promoter in tin-free MS/STP sealants, reactive hot-melt adhesives and high-temperature coatings. The alpha-effect enables fast moisture cure without organotin catalysts, and the isocyanurate core keeps adhesion at temperatures up to 200°C.

Manta AM311 is a high-molecular-weight adhesion promoter that combines a highly stable isocyanurate ring with three alpha-functional trimethoxysilyl groups.

Because the silicon atom is separated from the nitrogen atom by only a single methylene group (–CH2–), this unique structure induces the powerful “alpha-effect.” This results in extreme reactivity toward moisture, allowing for ultra-fast hydrolysis and crosslinking without the need for toxic heavy-metal (tin) catalysts.

It provides formulators with the ultimate solution: the exceptional thermal stability of an isocyanurate, combined with the rapid, tin-free curing kinetics of an alpha-silane.

Features

1. Alpha-Effect (Ultra-Fast Cure): The methoxy groups are hyper-reactive due to the alpha-position of the nitrogen atom, driving exceptionally fast moisture-curing kinetics at room temperature.
2. Tin-Free Formulation: Allows for the design of robust crosslinking systems without organotin catalysts, meeting the strictest global environmental and toxicity regulations.
3. Exceptional Thermal Stability: The robust isocyanurate core maintains structural integrity and adhesion even under sustained exposure to elevated temperatures (up to 200°C).
4. Zero Embrittlement: Enhances adhesion to difficult inorganic and organic substrates without over-crosslinking or stiffening the host polymer matrix.

Manta AM311 is specifically engineered for severe-duty and advanced eco-friendly polymer systems:

1. Tin-Free MS/STP Sealants: Functions as a highly reactive crosslinker and adhesion promoter for Silane-Modified Polymers (SMP) where fast curing and heavy-metal-free (tin-free) environmental profiles are strictly required.
2. High-Performance Hot Melt Adhesives (HMA): Acts as the premier silane additive in reactive polyolefin (POR) and polyurethane hot melts (PUR). It prevents vaporization losses during high-temp processing while providing explosive moisture-cure speed post-application.
3. Advanced Automotive & Aerospace Coatings: Utilized in high-temperature industrial coatings and structural adhesives that experience extreme thermal cycling and require uncompromising substrate adhesion.
4. Rapid-Cure Adhesives: Essential for assembly-line adhesives where immediate green strength and ultra-fast deep curing are critical for productivity.
