Modrin MF - silicone moldmaking compound

 

Characteristics

 
Pourable, condensation-curing,two-component silicone rubber that vulcanizes at room temperature.

 

Special characteristics

• Very good flowability and self-deaeration

• Medium Shore A hardness (approx. 20-25)

• Very good resistance to common casting resins

 

Application


MODRIN is a general-purpose mold-making material suitable for casting resins, wax, gypsum, etc. MODRIN is preferred when undercuts are involved and a certain inherent stability of the mold is required.

 


Processing

 

MODRIN   is cured by adding 3% of Catalyst C-88.
