ELASTOSIL® M 4643 A/B
Pourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature.
Main application: Making shrink-free molds with excellent reproduction
accuracy.
Food contact (FDA/BfR compliant).
Eigenschaften
- 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
Spezifische Merkmale von ELASTOSIL® M 4643 A/B
- Additionsvernetzend
- Beständigkeit gegenüber Gießharzen
- Fließfähig
- kein chemischer Schrumpf
- zweikomponentig
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.
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 B.
Caution:
A and B components may only be used together if they have the same batch number.
Lagerung
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.
