ELASTOSIL® P 7684/40 A/B can be used for molding applications in prosthetics.

Components A and B of ELASTOSIL® P 7684/40 A/B are homogeneously mixed in a ratio of 1 : 1 and vulcanize rapidly at temperatures above 100 °C. In a given application the required curing conditions (temperature and time) will also depend on the size and thickness of the specimen.

 

Detailed instructions for preparation and use are given in the brochure “Room Temperature Vulcanizing (RTV) Silicones - Material and Processing Guidelines”


Important note:
The platinum catalyst is in component A.

Caution!
Only A and B components with the same batch number may be processed together!

Storage

The 'Best use before end' date of each batch is shown on the product label.
