600-251 Flowable White Filled Encapsulant/Pottant

(2-part silicone)

600-251 is a platinum catalyzed, room temperature, addition cure silicone for potting and encapsulant applications requiring thermal conductivity.

UL 94 V-0 certification is pending for 600-251.
600-251 is a platinum catalyzed, room temperature, addition cure silicone for potting and encapsulant applications requiring thermal conductivity. The cure rate of 600-251 can be dramatically accelerated with moderate heat. 600-251 has good flowability and moderate thermal conductivity, with excellent dielectric properties and flame resistance.

600-251 is easy to process and calibrate on the manufacturing floor, featuring a 1:1 mix ratio with similar viscosities of Part A and Part B. Long working times facilitate deaeration. Application methods include manual mixing and pouring, or automated mixing and dispensing.
