TinSil® 80-Series Silicone Rubber
The TinSil® 80-Series is a line of tin-cured silicone mold rubbers that are designed to offer reduced shrinkage upon cure and during casting, longer storage/library life once cured and longer useable mold life than other tin-cured systems. The highest performance materials and processes have been used to develop this next-generation tin silicone for the most demanding casting applications.
- Shore A15, A30 & A40 hardness liquid mold rubbers
- Slightly longer library life compared to 70-Series tin silicones
- Release agent not necessary for most casting materials
- Excellent chemical resistance
- Reproduces finest detail
- Can be accelerated for rapid cure
- Ideal for the most demanding resin casting application
- These rubbers can be poured as supplied or thickened with TinThix liquid thickener for brush-on molds.
- resin casting (e.g., polyurethane, polyester, epoxy)
- foam casting
- plaster casting
- prototyping applications
- art foundry wax casting
- sculpture and décor reproduction
- hobby, craft, prop and display mold making and casting projects

NOTE: TinSil molds can inhibit the following casting materials: polyurethane rubbers and Poly-Optic 14-Series Casting Resins. This is especially the case in new tin-cured molds. Do not cast platinum-cured silicone in TinSil molds; they will not cure properly. Consider a platinum silicone rubber when using these casting materials.
|Product||Mix Ratio by Weight||Shore Hardness||Pour Time||Demold Time||Cured Color|
|TinSil® 80-15||1A:10B||A15||30 min.||24 hr.||Peach|
|TinSil® 80-30||1A:10B||A30||45 min.||24 hr.||Peach|
|TinSil® 80-40||1A:10B||A40||45 min.||24 hr.||Peach|
|Softener||Add Silicone Fluid 50cs to TinSil products for a lower-viscosity mix and a softer rubber.|
|Thickener||Add TinThix liquid thickener to thicken the liquid mix for application by brush or trowel.|
|Accelerator||Use TinSil FastCat in place of any TinSil Part A in order to accelerate cure and shorten demold time.|
