What is RTV-2 platinum cured liquid silicone rubber
Addition cure silicone rubber Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone
system that cures (RTV) to a flexible rubber. The polymerization can be accelerated by applying heat. The
silicone components are delivered as liquids, which once mixed and
cured into elastic and resistant material.
What are the Advantages of RTV-2 platinum cured silicone rubber
#Convenient to operate because the RTV property
#Easy to mix due to the low viscosity (6000~9000Cps)
#High duplication because of high tear and tensile strength
#Long library life with low shrinkage(0.01%)
#Food Safe,Skin Safe, Odor-free
What are the Applications of RTV-2 platinum cured silicone rubber
1.mold making for various materials
polyurethane and other reactive resins
Small pieces of cement,plaster,gypsum,concrete products.
Food like chocolate,fondants,desserts
Wax,candle,soap;
2.casting body parts,silicone dolls ,shoe insole.
Processing and Instructions of Addition Cure Liquid Silicones
Step 1
The ideal working temperature is around a constant 25°C. Best
results can be obtained at constant temperatures between 21°C and
26°C, in a clean, dry, dust-free environment. Avoid working in high
humidity.
Step 2
Measure product in accordance with your intended use. Prepare 1
part A to 1 part B by weight and pour into a clean, smooth-sided
container large enough to hold all the liquid and allow room for
mixing.
Step 3
The material must be mixed thoroughly for at least 5 minutes. make
sure to scrape the container sides, bottom, and corners as you mix.
Be careful not to whip excessive air into the mixture.
Step 4
Prepare a container(not silicone material),add the item and keep
them face up.
Pour the mixed silicone onto the container and distribute evenly to
cover the top of the item by at least 6-7mm
Step 5
Adjust the position and then let it cure, the bubbles will melt
gradually.
Step 6
Pull the item out of the mold
Note:
Contamination from sulfur (e.g., sulfur-based clay), amines, tin
compounds, cured polyester resin, some paints and some silicone
rubbers may inhibit surface cure of platinum-cured rubbers.
Apply a release agent, Although not usually necessary, a release
agent will make demolding easier when casting into most surfaces.
