Week 13 Students B

This week’s group assignment was to review the safety data sheets for our molding and casting materials and to compare test casts of each: Dariyah Strachan, Dylan Ferro, Ginny Foster, Stuart Christhilf, and David Tian.

Mixing: Stuart and David

We mixed the three material listed below. We mixed the 1:1 ratio of each material into seperate cups and left them to cure for their respective cure times.

What We Learned and Comparison: Ginny and Dariyah

Material Pot Life Cure Time Viscosity Durability (measured in tensile strength) Mixing Ratio Material Description Use For Making A Hard Cast
MoldStar (A) with MoldStar 16 fast (B) 6 minutes 30 minutes 12,500 cps, low 400 psi 1A:1B blue, very flexible Mold making
TASK-8 2.5 minutes 15 minutes 100 cps, very low, water-like 5,840 psi 1A:1B off-white, very hard Casting
MoldStar 31T 5 minutes 23 minutes 11,000 cps, low 423 psi, low 1A:1B cloudy, flexible Mold making

Data Sheets Review

MoldStar 31T TASK-8 MoldStar 16 fast - Flush eyes if contact is made with eyes - Wash skin if contact is made with skin, contact a physician to treat any chemical burns from TASK-8 - If ingested do not induce vomiting unless instrusted by a physican, drink water in small amounts if TASK-8 is ingested - Wear rubber or vinyl gloves when using any of the materials - Have good ventilation or wear a respirator - Wear safety glasses
