How to Make
(1) Precisely weigh A-components and B-component
(2) Mixing A,B component at the ratio of 1:1
(3)Deaeration: Put the mixture into vacuum device for defoameragent after stir.In the normal circumstances,there is no longer to deaerate since no bubble . Times for deaeration are about 5min to 10min under 30°C.when no air bubbles the next step can be processed
(4) Injection molding: inject material after Deaeration into mold under some proper condition ,such as press,temperature and time and so on .
Pot life
After the A and B components are mixed,YAC-29XXhight transparent liquid silicone rubber will remain usable for at least 96 hours at room temperature. refrigeration at lower temperature will significantly extend the usable life after mixing.
Notes
(1)Mixing A and B components properly and respectively before use!
(2)Materials should be sealed and stored and be run out during the pot life,otherwise leads to waste causing curing tardily.
(3)Curing condition relate to temperature ,while lower temperature reduce curing speed.
(4)The product belong to non-hazardous article.But flush with large of water when touched with mouth or eyes
Packing
Specification:40kg/group (20KG each of parts A and B ) 400Kg ( 200Kg each of parts A and B )
Storage and delivery
(1)Shelf life:1years(-25°C) at dry place
(2)Belong to non-hazardous article,can according to the general transportation of chemicals.
(3) Must be sealed and preserve carefully in case leaking during transportation!
