Factory price high quality UL94v0 fire sealant rtv2 silicone compound for electronic power supply insulation
Product Description
RTV-2 silicone rubber is generally named as two-part room temperature vulcanized silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% 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.
1.Two part of liquid fluid: liquid white silicone and curing agent.
2.Cure at room-temperature within 4-8 hours, but all performance will act perfectly when it cure within 2-4 hours.
3.Good fluidity and excellent operation.
4.Good resistance to weather, temperature, aging, acid.
5.Excellent tear strength, comfortable duplication times

Product Uses
Using instructions
Step 1: prepare the original molds Prepare an perfect mold modle and clean it totally(the release agent can be detergent, soapy water and Vaseline)before operation .Take 100g silicone material and 2~5g curing agent strictly and mix them evenly. *Notes:Make sure the toys and operation tool cleaned up totally to avoid uncure problem .
Step 2: Vacuum pumping
Without exception, this step takes less than 10 minutes.(normally is 5munites) Otherwise, it will cause cross linking reaction, and no more further steps will be available.
Step 3: Pouring casting or Brushing operation 1. For simple pattern products we suggest use pouring operation way, which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air . (mold with fine and precision patterns with low hardness.) 2.For delicate pattern products we suggest use brushing operation way.which can copy the pattern exactly .brushing way require high viscosity which won’t be easy to flow away and easy to brush(large size molds with high hardness) 3.The amount of the curing agent can be adjusted according to the actual requirements of the customer. If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.but we don’t suggest to add silicone oil avoid oil problem.
Step 4:Demoulding: After 35 hours later, can demould the silicone mold, it's will be better for molf to demould after 24 hours. Notes:The curing temperature and curing time can be adjustable according to the operation conditions.
Storage of Concrete balusters molds casting silicone rubber liquid:
When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, RTV2 Silicone Base and TC30 Curing agent have a usable life of 10 months from the date of production. After 10 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.
Functions
Liuqid Silicone can used for mold making or duplicating for poly resin crafts, PU crafts, PU resin crafts, gypsum crafts, unsaturated resin crafts, lighting and candles crafts, plastic toy, stationery gifts crafts industry, large statue buddha , relievo furniture , artificial fossils and so on.
