DESCRIPATION
MCSIL-2025 is a condensation cured silicone (tin catalyzed ) which is used to make rubber molds that can be used to cast polyurethanes, epoxy's, polyester unsaturated resins, cement, concrete, soap, wax, plaster, etc. It is easy to mix and de-air, and will cure at room temperature over virtually any surface. MCSIL-2025 is useful for applications where superior physical properties are required.
PRODUCT FEATURES
1. Good flow ability and long working time
2. High duplication times
3. Excellent tear strength
4. Easy de-mould from complex replica parts
5. Acid and alkali-resistance
6. Long library life
Technical Data
USING INSTRUCTION
1. Shake Part B catalyst well before using.
2. Weigh 100 parts base to 2 parts catalyst using an accurate scale and clean mixing cup.
3. Vigorously mix and scrape walls of container while mixing until color is uniform.
4. Place the silicone mixture in a vacuum chamber & degass. If you do not have a vacuum machine, pour the mixture 2'-3' above the pattern in a very thin stream.
5. Allow the silicone to cure and demold with care.
APPLICATIONS
RTV-2 silicones are specifically designed to replicate stones, marble, wood, and other construction materials, producing outstanding fidelity for every detail, including veins and surface texture. The various grades of architectural molding silicones enable builders to replicate accurately the look they desire while providing long mold life and excellent resistance against casting materials.
Package
Part A base silicone: 5kg, 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 250g, 800g/bottle, 1kg/bottle
Certificates
Storage
When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, Silicone Base and 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.
