White Tin Cure Molds Making RTV2 Liquid Silicone Rubber 15 Shore A
White Tin Cure Molds Making RTV2 Liquid Silicone Rubber 15 shore A
Description of Mold Making RTV2 Silicone Rubber:
MCSIL-2015 Mold Making RTV2 Silicone Rubber is generally named as two-part room temperature cure silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.
Various Applications of Mold Making RTV2 Silicone Rubber:
A: Cultural relic duplication, architectural decoration, statues
B: Polyester Resin crafts
C: Lighting ornaments, soap, candles molding
D: Plaster, Gypsum, Cement, Concrete decorations
F: Model design, product exploitation, etc.

Operation instructions of Mold Making RTV2 Silicone Rubber:
Correct mixing ratio
Component A is silicone rubber, and component B is curing agent or vulcanizing agent. Usually the mixing ratio will be 2-3%, e. G. To 100g silicone rubber should be added 2g catalyst and then mix them thoroughly. (Note: The weight of the silicone and catalyst should be weighed correctly).
Pouring the mixture and curing
Pour the misxed Part A base silicone and CA-30 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 you de-mold after 24 hours, it is will improve the replicate times of silicone mold.
Benefits of MC Silicone
Ease of processing
High resin resistance increasing the number of cast parts
Low linear shrinkage for greater accuracy
Easy release of shapes, including large pieces and complex geometries
High compatibility with water-rich casting materials such as gypsum
Increased compatibility with high performance concrete
Dimensional stability due to very low shrinkage
High mechanical properties over a range of flexibility
Certificates
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.
Package
Part A base silicone: 5kg, 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 250g, 800g/bottle, 1kg/bottle
