10. Molding and casting¶
We spent some time to familiarize ourselves with the lab’s safety measure and review the safety data sheets for each of your molding and casting materials.
Molding: SMOOTH ON SILICONE DRAGON SKIN ®
We read the Safety Data Sheet before using the material, especially the first aid measures as shown below to know what to do if you get exposure to the material and the best measure to follow to protect yourself.
the technical data sheet summarize in the follow TD PDF that give the user a clear steps to use the material, I highlighted the important points in yellow.
Casting: ART RESIN®
Before doing the casting by using ARTRESIN® we have to read the Safety Data Sheet to familiarize ourselves with the first aid measures after exposure to the material.
Also we have to go through the Technical Data Sheet to know the mixing ratio 1:1 & other important information about the material to have smooth casting.
For the Casting I’ll use Dragon Skin 30
Warning: You must read the safety Datasheet before using this material
Safety First: Use in a properly ventilated area (“room size” ventilation). Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Wear vinyl gloves only. Latex gloves will inhibit the cure of the rubber. www.smooth-on.com
Follow the instruction in the back of the box
For more Technical Data chick the Technical DataSheet
The most important data are shown in table below. ||| |------|-----| |Pot Life |45 minutes| |Cure Time |16 hours| |Mix Ratio By Volume| 1A:1B| |Mix Ratio By Weight| 1A:1B| |Color |Translucent|
Since all of us were sharing the same working table (large decent one for safety!), while working on different materials, we took the same safety precautions even if some of the martials were labeled as safer than some others, to reduce the risk of serious contamination.
We read the safety precautions in the datasheet and followed it to ensure everyone is safe while working and handling the material. We wore 2 vinyl gloves on top of each other, and tied any loose clothing with scotch tape, wore plastic aprons, a set of goggles, and an industrial mask on top of our existing masks.
The following table is a comparison between the kinds of materials that we used to create the molds in this week’s assignment:
|Student||Design||Mold Type||Ratio||measurements||Curing Time|
|Abdallah Alsafadi||PokeBall||Dragon Skin 30||1:1||133 g||16 H|
|Abdallah Alsafadi||Epoxy resin ( Art Resin)||1:1||30 g||16 H|
