GS-A30 hardness of 30 shore A,platinum cure silicone rubber
GS-A30 platinum cure silicone rubber addition silicone rubber food grade silicone rubber
GS-A30 is addition silicone rubber. It is two component ,flexible and good flowalibity.translucent , no smell ,non-toxic,the shrinkage is lower than 0.1% ,and it has a higher tear&tensile strength ,It is suitable to make mold for concrete castin,cement stone , resin crafted ,jewellry mold ,GRC casting,gypsum casting ,vaccum molding,etc.... The hardness of GS-A30 is moderate ,so it is better to make mould by pouring and brushing,it is best suitable for middle size product.Besides, the GS-A30 addition silicone is Eco-friendly , it can resist high temperature 240 centigrade without deformation.
Feature
1,Flexible and good flowability
2,easy to operation and demould
3,long lifetime
4,High tear&tensile strength
5,Food grade , no smell and non-toxic
6,high temperature resistent
Datasheet:
Item | Appearance | Hardness(shore A°) | Viscosity(CS) | Tensile strength(kgf /cm2) | Tear strength(kgf /cm2 ) |
GS-A30 | Translucent | 28±2 | 10000±1000 | ≥45 | ≥20 |
Elongation-break(%) | Mix ratio | Operation time(25 ℃ ) | Curing time (25 ℃ ) | shrinkage(%) | |
≥450 | 10:1/1:1 | 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 .
Note:
Pls kindly avoid to mix with the material as below. As this model is platinum cure silicone ,if it mixed with the below material ,it may cause that the silicone rubber will be not cured or it will be uncured fully. So, if your tools has used for condensation silicone , pls do remember thoroughly clean it before you use platinum silicone rubber.
1. Liquid condensation silicone ( condensation silicone not completely cured or organic
tin compounds )
2 .Sulphur, sulfide and sulfur rubber materials.
3. Amine compounds as well as contains the amine materials.
4 .Pewter solder flux.
