Applications of LS-AS312 3-(1,3-dimethylbutylidene)aminopropylmethyldiethoxysilane
1. One-component polyurethane sealants and adhesives
Used as latent adhesion promoter or curing support additive in 1K polyurethane systems. Verify cartridge stability, cure profile, adhesion, foaming tendency, modulus, and elongation in the target formulation.
2. Epoxy adhesives and sealants
Used in epoxy adhesive and sealant systems requiring latent amine functionality and dialkoxysilane reactivity. Verify cure behavior, pot life, adhesion, and storage stability before use.
3. Flexible sealant and coating systems
Used in sealant and coating formulations requiring controlled crosslinking and flexible cured properties. Verify impact resistance, flexibility, wet adhesion, and film properties by application testing.
4. Composite and filler treatment
Used for glass fiber, mineral filler, and inorganic surface treatment. Verify dispersion, compatibility, interfacial adhesion, and composite properties in the target polymer system.
5. Inks and casting resin systems
Used in printing ink and casting resin systems requiring latent amine functionality and alkoxysilane reactivity. Verify moisture resistance, adhesion, mechanical properties, and storage stability in the final formulation.
6. Moisture-sensitive formulations
Used where delayed amine reactivity or moisture-triggered amine generation is required. Verify compatibility, dosage, and by-product profile by formulation testing.
Packing of LS-AS312 3-(1,3-dimethylbutylidene)aminopropylmethyldiethoxysilane
In 200L drum and 1000L IBC.
Safety and Storage of LS-AS312 3-(1,3-dimethylbutylidene)aminopropylmethyldiethoxysilane
Store in a cool, dry, well-ventilated environment. Keep away from direct sunlight, heat, and open flames.
The ketimine structure is moisture-sensitive; premature moisture exposure causes hydrolysis, releasing MIBK and active amines.
Keep away from acids and alkalis; both accelerate hydrolysis.
Assess MIBK and ethanol VOC, toxicity, and workplace exposure per local regulations.
Shelf life: 12 months minimum from manufacture date when stored at ≤25°C in original tightly sealed unopened containers.
