Product Description

 
GTSIL-Tin cured Series:
Tin cure silicone rubber,which is  also named condersation silicone rubber,is generally a type of two-parts silicone rubber vulcanized at room temperature.
It is mainly used for model designin work of all kinds of products either with simple or intricate patterns,such as artificial/culutural stones,craft stones,gypsum crafts,GRC/GFRC/GRG for restoration,fireplaces,fountains,ornaments,resin crafts,resin marble works,shoe soles,art sculptures,decorative parts,candles,soaps,PU furniture moldings,etc.
With good resistance to deformation,heat,acid&alkali and expansion,finished silicone molds have very good performance in reproduction process of every fine details on designing models.
Application
GTSIL-T Series silicones are good for making molds for resin, polyester, pu, wax, plaster, gypsum, natural and synthetic cement ( artificial stone ),GRC, soap, etc….detailed application like following:
  1. Art and decoration: soap, candle, aquarium decoration, crafts molds.
  2. Furniture: concrete ,GFRC furniture, artificial stone molds
  3. Architecture: column, fountain molds, architectural restoration.
How to use
 
1.Substrate Preparation
The surface of the original should be clean and free of loose material. If necessary, and in particular with porous substrates, use a suitable release agent such as petroleum jelly or soap solution.


2. Mixing
Thoroughly stir Part A (silicone base) before use as filler separation may occur upon prolonged storage.
Weigh 100 grams Part A (silicone base) and 3 grams Part B (curing agent)  in a clean container. Mix together until the curing agent is completely dispersed in the base. Hand or mechanical mixing can be used, but do not mix for an extended period of time or allow the temperature to exceed 35°C (95°F). Mix suitably small quantities to ensure thorough mixing of the par A (silicone base) and part B (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 minutes 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.
Caution: prolonged vacuum will remove volatile components from the mix and may result in poor thick section cure and non-typical properties.
Note: If no vacuum de-airing equipment is available, air entrapment can be minimized by mixing a small quantity of par A (silicone base) and part B (curing agent), then using a brush, painting the original with a 1-2mm layer. Leave at room temperature until the surface is bubble free and the layer has begun to cure. Mix a further quantity of base and curing agent and proceed as follows to produce a final mold.

3. Pouring the Mixture and Curing
Pour the mixed Par A (silicone base) and Part B (curing agent) as soon as possible onto the original, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 24 hours at room temperature (22°C-24°C/ 71.6°F - 75.2°F) and the mold can then be separated from the original. If the working temperature is significantly lower, the cure time will be longer. If the room temperature or humidity is very high, the working time of the catalyzed mixture will be reduced. The final mechanical properties of the mold will be reached within 7 days.

How to make a mold in a pouring way?

2022 RTV-2 LSR Liquid Silicone Rubber Tin Silicone for Candle Molds Making

It's quite easy to make a mold with silicone rubber. However, we usually need to learn some knowledge about silicone before we start. As we know, silicone rubber, especially for mold-making, is a kind of wondrous molding material for many kinds of objects either in small size or big size. It is because there are so many advantages when using silicone rubber to make molds, such as odorless, non-toxic, high resistance to tearing, resistance to extreme temperature, high simulation precision, clear texture and lines, good performance, etc.
Now, let's learn a detailed method of how to make a mold with our magic silicone rubber.

1. Get a perfect original model ready.
Find a perfect original model. If the model is smooth and flawless enough, then we can definitely make a perfect mold with it. 

2. Fasten the frame and set the model.
Every piece of the frame must be sealed well to prevent silicone from leaking. Then, fix the model in the middle of the frame.

3. Metering, mixing.
Let's set tin cure silicone rubber for example, the mixing ratio of part A and part B is generally 100:2 or 100:3. You may use an electronic scale to measure the amount accurately. 

Then stirring the mixture evenly.

4. Pouring the mixture.
Pour 1/3 of the mixture into the frame from one of the angles slowly to avoid extra bubbles. Then pour the rest of the part into the frame.

5. Demoulding.
Take out the model when the mold gets cured completely (normally the curing time is 4h~6h). Then clean and trim the finished mold. 

Now, we come to the final step - set the mold in a cool and dry place. You may put it into production after 24hrs.

How to make a mold in a brushing way?
2022 RTV-2 LSR Liquid Silicone Rubber Tin Silicone for Candle Molds Making

Making a part mold is a little bit complicated than that in a pouring way.

2-part brush-on molds are ideal for replicating complex shapes that would otherwise be impossible with a pour (block) mold or glove mold. Using a brush-on technique gives the silicone more flex when demolding and require less silicone than pour molds. Splitting the mold into two parts can allow you to work around undercuts in a mold.

Note that you can add more than one mold part line, however this will increase the complexity of your mold.

With a good knowledge of silicones in advance, now we can just get down to the point.

1. Get a perfect original model ready.
Find a perfect original model. If the model is smooth and flawless enough, then we can definitely make a perfect mold with it. 

Examine your model and determine the best position for the part line. Remember to keep an eye out for undercuts and other awkward geometry.

Make registration keys. You may use a few nuts and filled the centers with clay. Build the part line out of clay and embed the registration keys.

Spray the model with mold release. This will aid in releasing the model after it has been molded.

2. Molding Side I

Once the mold release has had a few minutes to set, begin mixing the first batch of silicone.

Measure out an equal volume of part A and B. The first coat will be very thin so mix just enough to cover the entire model lightly.

In a new container combine parts A and B. Mix completely and begin applying to the model with a brush.

This layer will determine how accurately the mold captures the model, so be very precise and try to get every detail.

Be sure to brush gently, as the clay is soft and easily damaged by the brush.

The silicone will want to run off your model, you'll have to catch the bits that run off and reapply them to the model.

As the silicone begins to cure, the drips will become less frequent. GTSIL- P 20 has a 25 minute pot life so be patient, you may have to stand there for quite a while until it stops.

Once the first coat has partially cured (no longer tacky, dry to the touch), The second layer will be thicker than the first. I find it easier to apply the next few layers with a spatula like device than a brush.

On the final layers a thickening agent can be added to the silicone to keep it from dripping off the model and allow you to build up certain areas, like the part line. You only need a few drops of thickening agent to make it stiff enough. Keep applying layers until you have a consistent .25"-.5" wall thickness on the model. Try to make the outer layer as smooth as possible. This will aid in releasing the mother mold from the silicone mold later.

3. Molding Side II

Once the first half of your mold has cured completely, remove the clay part line barrier.

Be sure to remove all registration keys that may be embedded in the silicone.

Clean up the silicone part line as best as possible and spray the second half of the mold with release agent. Because silicone will be applied directly to more silicone on the part line, it is a good idea to make sure there is a lot of release agent in that area. Apply several coats of release agent, wait a few minutes between each coat. If the part line fuses it'll be difficult or even impossible to separate the two halves and your model will be trapped inside.

After the mold release has set, apply silicone to the second half of the mold as you did for the first half. Remember to build some thickness along the part line.
