GS-C40 hardness of 40 shore A , condensation silicone rubber
GS-C40 condensation liquid silicone rubber ,mold making silicone rubber
GS-C40 is condensation silicone rubber. It is two component ,mix ratio is 100:3, flexible. It can be used to make concrete casting ,gypsum casting ,resin crafted,manual mold,PU casting ,cement stone casting ,etc... Because the hardness of C40 is a little higher ,the viscosity is also a little higher , so it is better to make mold by brushing ,it is suitable for big size product.
Feature
1,Flexible and good flowability
2,easy to operation and demould
3,long lifetime
4,High tear&tensile strength
Datasheet:
Item | Appearance | Hardness(shore A°) | Viscosity(CS) | Tensile strength(kgf /cm2) | Tear strength(kgf /cm2 ) |
GS-C40 | White | 36±2 | 23000±3000 | ≥43 | ≥19 |
Elongation-break(%) | Mix ratio | Operation time(25 ℃ ) | Curing time (25 ℃ ) | shrinkage(%) | |
≥420 | 100:3 | 30-45 mins | 3~4 h | ≤0.3% |
Operation instuction:
1,weigh the silicone rubber and catalyst with the ratio of 100:3.(If you need to add ur own pigment , pls add the pigment into the silicone as ratio 0.5%)
2,Stiring them evently , then transfer them to the vacuum machine to release the bubble.
3, Pls clean your product before you pour or brush the silione rubber on your product .If your product is very complicated , you can spray some release agent on your product before pour silicone.
4,After 3~4 hours ,the silicone rubber will be dried fully , then you can demould it .
Dear customer , if you have any question or problem about the technique of making mold ,pls feel free to contact us , we will be happy to provide technical supports.
