Liquid Silicone for Capitals and Columns Casting

Liquid Silicone for Capitals and Columns Casting feature description:

 A. Workability

The base compound and curing agent are mixed and then poured into the mold to create a silicone rubber mold quickly. Workable time and cure time can be adjusted. 

B. Mold-releasability

The cured rubber releases easily from the mold, so mold-release agents (soapy water, wax, etc.) are unnecessary.

C.Dimensional stability

These rubbers offer good dimensional stability, with little shrinkage.

D. Flowability

They have excellent flowability, so the original form is reproduced accurately. This includes even intricate shapes and details such as fingerprints and wood grain.

E.Heat and chemical resistance

These rubbers have outstanding resistance to heat and chemicals.

F.Deep-section curability

Moldmaking RTV silicone rubber compound cures uniformly throughout the mold, regardless of thickness

G.Non-exothermic

No heat is generated during curing, meaning no adverse effects to the original.

Liquid Silicone for Capitals and Columns Casting curing agent and silicone proportion and reaction(Under room-temperature-25C)

1.Added with 2 percent of curing agent, silicone can still flow within 1.2-1.6 hours, mold can be released in 7-8 hours.
2.Added with 3 percent of curing agent, silicone can still flow within 1-1.2 hours, mold can be released in 6-7 hours.
3.Added with 4 percent of curing agent, silicone can still flow within 40-50 minutes, mold can be released in 5-6 hours.
