Liquid Mold Making Silicone Rubber RTV2 Tin Silicone Concrete, Plaster Molds

Product Specification

Description of MCSIL-20 series RTV2 silicone liquid rubber:

MCSIL-20 series 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.

 

Advantages of MCSIL-20 series RTV2 silicone liquid rubber:

 

1.Good flowability (20000~24000Cps)

2.Long working time(30~40min, 60~80min,90~100min)

3. Medium hardness

4. High tear and tensile strength

5. Easy de-mould from complex replica parts

6. Acid and alkali-resistance

7. Low linear shrinkage(0.2%)

 

Applications of MCSIL-20 series RTV2 silicone liquid rubber:
 

MCSIL-20series RTV2 silicone rubber also can be applied in the reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. Etc.

INSTRUCTION of Tin Cured RTV2 silicone liquid rubber:

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 2 parts of Curing Agent in a clean container.Thoroughly stir Part A base silicone before use, as filler separation may occur uponprolonged storage. Mixing Part A and Part B evenly until the CA30 completely dispersed in the base. 

It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 3-5 mins under vacuum,the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.

Pouring the mixture and curing

Pour the mixed Part A base silicone and part B the curing agent as soon as possible onto the original, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 6 hours (or faster by different mixing ratio or room temperature), we advice youde-mold after 24 hours, it is will improve the replicate times of silicone mold.

Package of MCSIL-20 series Tin Cured RTV2 silicone liquid rubber:

Part A base silicone: 1kg /Jar; 5kg per bucket, 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 250g, 800g/bottle, 1kg/bottle

Storage

When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, Silicone Base and Curing agent have a usable life of 12 months from the date of production. After 12 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
