ELASTOSIL® A33 IVORY
Moisture Curing Silicone Rubber (RTV-1)
ELASTOSIL® A33 IVORY is a non-slump RTV-1 silicone rubber, which cures at room temperature. During vulcanization it
splits off an organic amine.
Properties
• amine-curing system
• no use of organotin catalysts
• good heat stability
• excellent primerless adhesion to many substrates
• Recommended service temperature from -45 °C to +200 °C
• max. recommended short term peak temperature exposure 220°C
Specific features
• Non-slump
• Oil resistant
• One-component

Processing
ELASTOSIL® A33 shows good primerless adhesion to many substrates. We recommend running preliminary tests to
optimize conditions for the particular application.
Detailed processing instructions are given in our brochure “ROOM TEMPERATURE VULCANIZING (RTV)
SILICONES - MATERIAL AND PROCESSING GUIDELINES
Packaging and storage
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.
Safety notes
During vulcanization of ELASTOSIL® A33 IVORY, an organic amine is split off. These vapours should not be inhaled for long
periods or in high concentration. Work areas should therefore be well ventilated. Contact of unvulcanized silicone rubber
with eyes and mucous membranes must be avoided as this would cause irritation. However if it does happen, rinse the
affected area thoroughly with water.
Comprehensive instructions are given in the corresponding Material Safety Data Sheets. They are available on request from
WACKER subsidiaries or may be printed via WACKER web site http://www.wacker.com.
