MIXING:
TC-5024 A/B is processed by adding curing agent "B" at a ratio of 10 parts by weight to 100 parts by weight of "A". TC-5024 "B" side is tinted blue so that when mixing the "A" and "B" sides together, the colorant in the "B" side will provide a visible means of insuring that a uniform mix is acquired. Mix for 2 to 3 minutes in a clean container, then transfer material to another clean container and mix for another 2 to 3 minutes.
INHIBITION:
New molds made with tin catalyzed silicones often have a tendency to inhibit the cure ofsofter elastomericand aliphatic urethanesthat are cast against the silicone. Post curinga new mold at 150F for 24 hours may reduce the cure inhibition problem in most cases. It is also recommended that the mold surface be washed thoroughly with soap and warm water then dried before use.
