Methyltris(methylethylketoxime)silane Typical Properties

Methyltris(methylethylketoxime)silane Properties

1. Methyltris(methylethylketoxime)silane is an oxime silane-based crosslinker 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.

2. Methyltris(methylethylketoxime)silane is a clear colorless to pale yellow fluid with a typical smell (MEKO). The product readily hydrolyzes upon contact with moisture.

Methyltris(methylethylketoxime)silane Application

1. Be used as a cross-linking agent for RTV.

2. Methyltris(methylethylketoxime) silane 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.
