Applications of Silfluo LS-M81 3-(Diethylamino)propyltrimethoxysilane
1. Neutral-cure RTV silicone sealants
Used as autocatalytic crosslinker and adhesion promoter in one-part neutral-cure RTV silicone sealants. Verify deep-section cure rate, unprimed substrate adhesion, and storage stability in the target formulation.
2. SPUR and MS polymer systems
Used as reactive silane additive in silyl-terminated polyurethane and MS polymer systems. Verify cure profile, adhesion, color stability, and storage stability in the final formulation.
3. Coatings and primers
Used as surface primer and reactive additive in coating systems for metallic and inorganic substrates. Verify wet adhesion and corrosion resistance in the target system.
4. Mineral filler treatment
Used as surface modifier for inorganic fillers in composite compounding. Verify viscosity change, filler dispersion, and compatibility in the target compound.
