Multi Specification Liquid Silicone Rubber For Different Workshop
Molding Processes
Description
Tin cured liquid silicone rubber, also known as condensed liquid
silicone rubber, is composed of AB components, usually mixed in a
ratio of 100:2. Tin cured can cure at room temperature, so it is
called RTV silicone rubber
Application
HN-620 A/B is industrial liquid silicone rubber specially designed
for construction mold fabrication. It is ideal for replicating
molds of large stone, gypsum products, cement components, cultural
stone, artificial stone, Roman columns, stone carvings and other
architectural & decorative pieces. Additionally, it can be made
into split molds for resin crafts, gypsum artworks, handmade soap,
tire casting molds and various craft items.
Feature
1. Suitable viscosity to adapt to pouring or brushing molds.
2. No oil output
3. Good tear resistance and easy demolding
4. Can replicate very fine patterns
5. Multiple times of mold flipping
6. Stable chemical resistance, heat resistance, corrosion
resistance, and aging resistance.
7. Low shrinkage rate
8. Shelf life of 12 months
Operation method:
1. Mix the mold adhesive and curing agent in a weight ratio of
100:2-3 and stir evenly;
2. Place the mixed and stirred silicone gel into a vacuum machine
for vacuum exhaust bubble treatment. The advantage of doing so is
to make the product smooth and free of bubbles (without a vacuum
machine, the curing time can be extended to allow bubbles to
naturally discharge, but the effect is not very ideal);
3. Spray (apply) a layer of release agent on the already made mold
and mold frame, fix the mold in the middle, and slowly and steadily
pour the liquid silicone that has discharged the bubbles into the
mold frame until the silicone completely covers the mold, and then
let it rest until it fully solidifies;
4. Wait until the silicone gel of the mold is fully cured before
demolding, and remove the silicone mold for edge treatment;
5. It is recommended to leave the silicone mold for 24 hours before
putting it into use, in order to achieve the best use effect of the
mold.
Storage and Transportation
1. Put the silicone in the cool and dry place.
2. Transport as non-dangerous products.
3. Avoid contact with skin with hardener ofTin cure silicone. In
case of contact,wipe itof with a cloth and wash it off with soap
andwater.
4. Please read the "MSDS" Materials safetyData Sheet of the product
carefully before use.
