LS-AM121 Methyl [n-(dimethoxymethyl)silylmethyl]carbamate
CAS NO.: 23432-65-7

Name: LS-AM121 Methyl [n-(dimethoxymethyl)silylmethyl]carbamate
Brand: Nanjing Silfluo New Material Co., Ltd.
Availability: InStock

Silfluo LS-AM121 is Methyl N-[(dimethoxymethylsilyl)methyl]carbamate, an alpha-functional carbamate silane.

The molecule contains a carbamate group and a methyldimethoxysilyl group connected through a methylene bridge.

The alpha-silane structure gives different hydrolysis and moisture-scavenging behavior compared with conventional gamma-functional silanes.

Unlike trialkoxysilanes, LS-AM121 carries a dialkoxysilane structure, giving controlled crosslink density in moisture-curing systems.

Used as moisture-scavenging additive, reactive silane component, or chain-extending silane in silane-terminated polymer, SMP, SPUR, polyurethane, and hybrid adhesive or sealant systems.

Moisture-scavenging performance, viscosity stability, cure behavior, modulus, elongation, and storage stability require verification in the target formulation.

Performance equivalent to Wacker GENIOSIL XL 65.

Applications of LS-AM121 Methyl [n-(dimethoxymethyl)silylmethyl]carbamate

1. SMP, SPUR, and silane-terminated polymer systems

Used as reactive silane component, moisture-scavenging additive, or chain-extending silane in silane-modified polymer and silyl-terminated polyurethane systems. Verify moisture content, viscosity, cure profile, modulus, elongation, and storage stability in the target formulation.

2. Low-modulus sealant formulations

Used in sealant systems requiring controlled crosslinking and flexible cured properties. Test modulus, movement capability, adhesion, and aging behavior in the final sealant formulation.

3. Moisture-curing polyurethane and hybrid adhesives

Used in 1K polyurethane and hybrid adhesive systems requiring moisture control and alkoxysilane functionality. Verify CO₂ formation, foaming tendency, cure behavior, and pot life by formulation testing.

4. Construction and industrial sealants

Used in construction and industrial sealant formulations. Test adhesion, weathering resistance, movement capability, and mechanical properties per the target application.

5. Moisture-sensitive formulations

Used as moisture-control additive in moisture-sensitive systems. Confirm compatibility, dosage, storage stability, and final cure behavior before scale-up.

Packaging of LS-AM121 Methyl [n-(dimethoxymethyl)silylmethyl]carbamate

In 500g, 1000g, 25kg pail, 200kg drum.

Safety and Storage of LS-AM121 Methyl [n-(dimethoxymethyl)silylmethyl]carbamate

Storage Conditions: Keep tightly closed in a cool, strictly dry, and well-ventilated area. Protect from direct sunlight and ambient moisture. Premature exposure to humidity will trigger rapid hydrolysis.

Shelf Life: Minimum 9 months when stored in the original, unopened containers under proper conditions.

Transportation: Shipped as a non-hazardous substance according to transport regulations.
