1. Description
YJS-535 is a type of hard silicone with hardness Shore A 35. It is a kind of of two- component materials consisting of a flowable part A which when mixed with the curing agent or catalyst,cures at room temperature by a condensation reaction. It is widely used for making molds for artificial stone, gypsum casting, grc, grfc, cement/concrete decorative products and etc.

2. Features
-Amazing fluidity and easy to operate
-Complex design available
-Not Oily
-Stable quality, non-toxic and odorless catalyst provided
-Easy de-molding
-Excellent tension and tear strength
-High performance in duplication
-Shrinkage is almost zero (below 0.2)
-Excellent resistance to weather, temperature, aging, acid and aging-proofing.

4. Using instructions 
Step 1: Prepare and clean the prototype.
You must make sure your original molds perfect. fix the original mold on a board , then using some assistant material(like cardpaper) to make a frame for to surround the prototype. The frame is no need ,if we make the mold by brushing way .
 
 Step 2: Take the silicone and catalyst as the ratio 100:2 (silicone:catalyst=100:2) ,mix the silicone rubber and catalyst evenly. 
*Notes: Molding silicon rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of flowing liquid and part B is the curing agent. Remember to mix part A and part B evenly, otherwise the silicon rubber will be partly solidified and this will bring troubles for your final operation. What’s more, the finished molds will have a short life. All of these will cause a waste of silicon rubber.
 
Step 3: Vacuum pumping
After mixed the silicone evenly, it is better to release the bubble by Vacuum pumping.
Step 4: Pouring cast or brushing cast
After released the bubble, we can pour/brush the silicone rubber on the prototype 
*Notes:Please finished all the steped within the operation time .If not it will cause cross linking reaction, and no more further steps will be available.So,we have to pay attention to the pot life and curing time.

5.Appearance
Part A: Silicone rubber is a white liquid
Part B: Catalyst is a non-toxic and odorless liquid, white transparent color.
ATT: We can provide fast/medium/slow catalyst of for hot, warm or cold season.

6.SHELF LIFE:
When stored at or below 32°C (89.6°F) in the original unopened containers, YJS-5 series Silicone Base and its Curing Agents have a usable life of 10 months.

7.Package
Silicone base:1kg/drum; 20kg/drum;25kg/drum;200kg/drum.
Curing Agent: 30g/bottle; 1kg/bottle

 


Q:How to distinguish between inorganic chemicals and organic chemicals
Organic chemicals is probably the organic, organic concept you can see Encyclopedia details
Q:Hazardous Chemicals Inorganic Classes, Organic Classes What does it mean?
Hazardous chemicals refer to highly toxic chemicals and other chemicals that are harmful to humans, facilities and the environment, which are toxic, corrosive, explosive, burning and burning. Including explosives, compressed and liquefied gases, flammable liquids, flammable solids, spontaneous combustion and wet flammable materials, oxidants and organic peroxides, toxic and corrosive substances, etc.
Q:Storage of organic chemicals in the warehouse, ventilation requirements
The use of anti-static ventilation fan ventilation.
Q:Is the resin a dangerous chemical? Is there any other alias?
Liquid resin containing organic solvent is a dangerous chemical
Q:Calcium fatty acid is an organic or inorganic chemical
Organic chemicals. Most of the carbon compounds in addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.
