Product description
Structural formula:
Empirical formula: C13H27N3O3Si
Molecular weight: 301.46
CAS No.: 22984-54-9
Chemical name:
Methyltris(methylethylketoxime)silane
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 smell (MEKO).The product readily hydrolyzes upon contact with moisture.

Reactivity
D-33 readily undergoes 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 and performance
Be used as a cross-linking agengt for RTV.
D-33 is often the main crosslinker of choice for oxime silicone sealants and can be used by itself 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.
Product safety, handling and storage
Customers considering the use of this product should review the latest Material Safety Data Sheet and label for product safety information, handling instructions, personal protective equipment if necessary, and any special storage condition required. The “Best use before end” date of each batch is shown on the
product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
