Week 11: Molding and Casting

Group Assignment:

• Review the safety data sheets for each of your molding and casting materials

Group Assignment:

• Review the safety data sheets for each of your molding and casting materials

Safety:

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 safer than others, to reduce the risk of accidental 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 two sets of vinyl gloves on top of each other, tied any loose clothing with tape, wore plastic aprons, a set of goggles, and an industrial mask on top of our existing masks.

Mold Max 14NV:

Advantages:

• Fast cure time (4 hours)

• Doesn’t require vacuum degassing

• Has low viscosity for easy mixing and pouring

Disadvantages:

• Has to be measured by weight not volume

• Not safe to touch skin

• Has limited shelf life

Safety:

• requires a lot of safety measures as it is dangerous to touch the skin and to inhale.

Safety datasheet:

Casting:

EpoxAcast™ 690

Advantages:

• Nice finishing

• Rigid if done properly

• Pure and crystal look

Disadvantages:

• Curing Time 24 hours, Pot time is 5 hours which won’t be practical if we need to add colors or other items to the cast since we have to wait until we start the next step

• Ratio 100:30 by weight which means that we need to be careful while taking the measurements

• Result is full of bubbles if heat/vacuum is not used

Safety:

• requires a lot of safety measures as it is dangerous to touch the skin and to inhale.
