Product Information

Chemical Name:  Methyl tri methyl ethyl ketoxime silane

Product Code: D-33

Molecular Formula: C₁₃H₂₇N₃O₃Si

Molecular Weight: 301.46

CAS NO.:  22984-54-9

Properties

D-33 is oxime silane-based crosslinkers for producing neutral moisture-curing silicone sealants. Using these silane compounds, hydroxyl-functionalized silicone polymers are crosslinked to obtain a silicone elastomer under the effect of a catalyst and moisture. When using D-33, no acetic acid or amine is released in contrast to acid or alkaline cross- linking systems, but methyl ethylketoxime. As this cleavage product reacts neutrally, sealing compounds based on crosslinker oxime can be used even on sensitive substrates such as marble.

D-33 is a clear colorless to pale yellow fluid with a typical odor (MEKO).The product readily hydrolyzes upon contact with moisture.

Technical Data

Note: the above data is for reference only, cannot be as a technical specification.

Reactivity

D-33 will hydrolysis upon contact with moisture.

D-33 are liquid raw materials for neutral condensation curing silicone sealants. In the presence of a (tin) catalyst these silanes react with hydroxyfunctional silicone polymers; exposure to moisture results in the formation of crosslinked, elastomeric silicones.

Application

Crosslinker for RTV-1 sealant. D-33 is often the main crosslinker for oxime silicone sealants and can be used alone or in combination with other oximesilanes to provide the sealant with targeted properties (such as desired cure rate, adhesion, etc). In contrast to acidic or basic curing systems, no acidic acid or amine, but 2-butanoneoxime is liberated during application. Due to the neutral character of

2-butanoneoxime, sealants based on D-33 can be applied even on (corrosion) sensitive substrates like metals or marble.
