Wacker Chemical Corp. Silicone Rubber Mold Making Compound ELASTOSIL® M4643 A/B

Description
Pourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature. Special features very good flow fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat medium Shore A hardness (approx. 48) high tear strength long-term stability of the vulcanizate’s mechanical properties outstanding resistance to common casting resins Application Due to its outstanding resistance to casting resins as well as its superior mechanical properties ELASTOSIL® M 4643 A/B is perfectly suitable for all molds of models with undercuts that are to be reproduced in casting resins, and a certain inherent rigidity of the molds is required. As a medium-Shore addition-curing RTV-2 silicone rubber that cures without undergoing dimensional shrinkage, ELASTOSIL® M 4643 A/B is also extremely suitable for casting all other common reproduction materials, particularly if absolutely accurate copies of models with undercuts are required.
