- 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.

Technical Details & Test Data
- 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.
Storage & Handling
- Product Handling and Storage
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.
