Name: Evonik Dynasylan M2-O2 Dimethyldibutanoneoximesilane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Evonik Dynasylan M2-O2 Dimethyldibutanoneoximesilane

Highly reactive bis-silane coupling agent with two hydrolyzable butanone oxime groups per molecule.
Excellent shelf stability in anhydrous conditions due to the sterically hindered butanone oxime leaving group.
Enables efficient covalent bonding between organic polymers and inorganic substrates such as glass, metals, and minerals.
Low volatility and reduced odor compared to acetoxysilanes, supporting safer industrial handling.
Compatible with moisture-cure RTV silicones, hybrid polymers, and silane-modified polymers (SMPs).

Typical Applications Of Evonik Dynasylan M2-O2 Dimethyldibutanoneoximesilane

Adhesion promoters in high-performance automotive sealants and structural bonding agents.
Surface modifier for fillers and pigments in coatings, adhesives, and elastomers.
Crosslinker in silane-terminated polymer (STP) formulations for construction sealants.
Reactive additive in fiber-reinforced composites to enhance fiber–matrix interfacial strength.
Key ingredient in corrosion-inhibiting primers for aluminum and steel substrates.
