DESCRIPATION
RXD HY-628 mold making silicone rubber is a two-component material silicone rubber,consisting of Part A base silicone and Part B organic tin 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?
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.
Mixing
Please weight 100 Part A base and 2 parts of organic tin 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 part B 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 35°C. 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 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 organic tin 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.
STORAGE
When stored at or below 30°C in the original unopened containers,SILASTIC RTV-903 Base and Curing agent have a usable life of 12 months.from the date of production.After 12 months stock,pls use the Stir to mixing the Part A silicone for some mins, then the silicone can be use again,no influence for other performance.
