Applications of LS-MVOS Vinylmethylbis(methylethylketoximino)silane
1. Neutral-cure RTV silicone sealants
Used as modifying co-crosslinker in oxime-cure RTV silicone sealants. Verify cure profile, skin-over time, through-cure, modulus, elongation, and storage stability in the target formulation.
2. Low-modulus sealant formulations
Used in sealant systems requiring lower modulus and flexible cured properties. Test movement capability, adhesion, and aging behavior in the final sealant formulation.
3. Soft silicone elastomers
Used in RTV silicone elastomers requiring softer cured properties. Verify hardness, tensile strength, elongation, tear strength, and compression behavior in the target system.
4. Electronic potting and encapsulation
Used in stress-relief silicone potting materials. Verify modulus, adhesion, dielectric properties, thermal cycling behavior, and compatibility with electronic components before use.
5. Customized oxime crosslinker blends
Blended with trifunctional oxime crosslinkers for formulation adjustment. Verify blend ratio, viscosity, cure profile, by-product profile, and storage stability by formulation testing.
