DESCRIPATION
SILASTIC RTV328 moldmaking rubber is a two-componet material,consisting of Part A base silicone and Part B CA30 curing agent,cures at room temperature by a condensation reaction. These materials can be cast into the cured silicone mold:plaster,polyurethane,PU,GRC,cement,resin,polyester,wax etc..
How to make the silicone mold?
l 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,pls use a suitable mold release agent such as soap water,detergent,waseline or petroleum jelly.
Silastic RTV silicone rubber Mixing
Please weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container.Thoroughly stir Part A base silicone before use, as filler separation may accour upon prolonged storage. Mixing Part A and Part B evenly until the CA30 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.
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 1—2 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 accour on vacuum de-airing the mixture. So a suitably large container should be chosen.
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.
Silastic RTV silicone rubber STORAGE
When stored at or below 30 C(85F) in the original unopened containers, HY RTV 638 SILICONE Base and CA30 Curing agent have a usable life of 12months.from the date of production.
