High Strength Mold Making RTV-2 Silicone Rubber For Plaster Concrete Mold Making

MCSIL-930 RTV2 silicone rubber is a kind of two-component material, that is the mold making silicone rubber made up of Part A base silicone and Part B curing agent. The mixed Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction,then become a silicone rubber mold that can be used for objects reproduction.

 

FEATURES

・Good flow ability and long working time

・Medium hardness

・High tear and tensile strength

・Easy de-mould from complex replica parts

・Acid and alkali-resistance

・Low linear shrinkage

 

APPLICATIONS

MC Silicone MCSIL-930 suited for reproduction of plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds, etc.

How to make the silicone mold?

  • The surface of the original should be clean and free of loose material. If your products with thin flower patterns, and especially with porous substrates, please use a suitable mold release agent such as soap water, detergent, Vaseline or petroleum jelly.
  • Mixing

Please weight 100 Part A base and 10 parts of CA30-10 Curing Agent in a clean container. Thoroughly stir Part A base silicone before use, as filler separation may occur upon prolonged storage. Mixing Part A and Part B evenly until the CA30-10 completely dispersed in the base. Hand or mechanical mixing can be used, but do not for an extended period of time or allow the temperature to exceed 35C (95F). Mix suitably small quantities to ensure thorough mixing of base and curing agent.

 

Pouring the mixture and curing

Pour the mixed Part A base silicone and CA30-10 curing agent as soon as possible onto the original, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 8 hours (or faster by different mixing ratio or room temperature), we advice you de-mold after 24 hours, it is will improve the replicate times of silicone mold.

STORAGE

When stored at or below 30 C (85F) in the original unopened containers, MC silicone RTV9920 Base and CA30-10 Curing agent have a usable life of 10 months from the date of production. After 10 months stock, please use the Stir to mixing the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
