What is the difference between mold Star 15 and mold Star 30?
Mold Star™ mold rubbers are easy to use platinum silicones which are mixed 1A:1B by volume (no weighing scale necessary). Mold Star™ silicones feature relatively low viscosities and vacuum degassing is not required for most applications. Mold Star™ 30 is a harder material, with a 30A Shore hardness.
How long does mold Star 15 take to cure?
4 hours
The pot life of Mold Star™ 15 SLOW is 50 minutes and cure time is 4 hours at room temperature.
Which silicone is best for molding?
One of the best materials for making detailed molds is silicone RTV mold-making rubber. The RTV stands for “Room Temperature Vulcanizing,” which means that once you mix up the materials, you don’t need to put it in an oven to cure it.
Can you put rubber in a silicone mold?
Generally, silicone RTV mold making rubber does not stick to anything, and nothing will stick to it.
What is platinum grade silicone?
Platinum silicone is a type of silicone that uses only platinum (precious metal) as a catalyser, which increases its quality, apart from silicone’s other properties. This is the ideal material for manufacturing moulds or products that will come into contact with food.
How long does it take mold Star 30 to cure?
6 hours

How do you use an ease release?
Instructions
- Shake well before using.
- Hold spritzer pump 6 in./ 15 cm. from surface to be sprayed.
- Apply a light mist coating to all surfaces that will contact the rubber or casting material including model or mold surface and surrounding forms.
- Using a soft brush, brush the release agent over all surfaces.
How long will a silicone mold last?
Platinum catalyst silicone molds (like our Food Grade silicone or silicone putty) last 20+ years when stored properly. Latex molds last 10-20 years when stored properly. Urethane rubber molds (like our 75A urethane rubber) last 20+ years when stored properly.
What is Mould release spray?
Mould Release Spray is designed to give fast, efficient and clean release with faithful reproduction of the mould profile however complex the mould or minute the detail. Suitable for use on all plastic and rubber mould tools including injection, compression and blow mouldings.
What material can you use to make a silicone mold?
The basic material for the production of silicone molds is silicone rubber. You can get it at your local dealer. Silicone rubber is a soft mass that hardens very quickly and is then extremely elastic.
What material can I use in silicone mold?
The silicone RTV system can be used to make any kind of mold. Silicone exhibits very low shrinkage and excellent long-term retention of rubber proprieties. Casting enthusiasts favor silicone when casting cement, vinyl, wax, plaster, low-melt metals, and various kinds of resin.
How long does it take for mold star 15 slow silicone to dry?
Curing – Allow Mold Star 15 SLOW silicone rubber to cure for 4 hours at room temperature (73°F/23°C) before demolding. Vacuum Degassing – Although not necessary, vacuum degassing helps eliminate any entrapped air in pourable silicone rubber Mold Performance – The physical life of the mold depends on how you use it (materials cast, frequency, etc.).
What type of silicones are used in mold star Rubber?
Mold Star rubbers are easy to use platinum silicones which are mixed 1A:1B by volume (no weighing scale necessary). Mold Star silicones feature relatively low viscosities and vacuum degassing is not required for most applications. Mold Star silicones cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage.
What is the pot life of mold star™ 15 slow?
The pot life of Mold Star™ 15 SLOW is 50 minutes and cure time is 4 hours at room temperature. Mold Star™ silicones cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage. Molds made with Mold Star™ will last a long time in your mold library and are good for casting wax, gypsum, resins, and other materials.
What is mold star 15 made of?
Mold Star™ 15 reflects perfect detail. Mold Star™ 15 is an easy to use Shore 15A platinum silicone that is mixed 1A:1B by volume (no weighing scale necessary). It features a relatively low viscosity and vacuum degassing is not required for most applications.
