addition high transparent food grade liquid silicone rubber for cake molding

Descripation:

RTV-2 mold making addition silicone rubber is generally named as two-part silicone rubber that vulcanizes at room temperature.Part A is a flow able liquid ,part B is the platinum catalyst.

Characteristical:

• Easy to use

• Almost nil shrinkage

• Use platinum catalyst

• Excellent non-stick effect

• High degree of precision in reproduction
• High dimensional stability over time and non-deformability

• Food grade silicone (environmental,odorless and nontoxic)

• High resistance to high temperature and aging(resist -60 to 200°C)

• High chemical resistance to aggressive components of some types of resins
• Good tear strength (this feature ensures higher resistance to wearing and shearing)

Application:

• PU resin casting

• General mold making

• GRC and concrete molding

• Superior manual mold design

• Food grade molding application

• Rapid prototyping(urethane casting/silicone tooling/vacuum casting)

Parameter:

Catalyst

Silicone

How to make mold?

1.Mixing

Please weight 10 Part A base and 1 parts of platinum Catalyst 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 catalyst.

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.

2.Pouring the mixture and curing

Pour the mixed Part A base silicone and part B platinum catalyst as soon as possible onto the original,avoiding air entrapment.The catalyzed material will cure to a flexible rubber within 24 hours(or faster by different mixing ratio or room temperature).

Storage:

When stored at or below 30°C in the original unopened containers,SILASTIC Base and platinum Catalyst 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.
