DynaPlast® T-1 Tooling Plaster

DynaPlast® T-1 Tooling Plaster is a good general purpose tooling plaster. It has good plasticity and can be easily re-tempered with water to extend the material’s open time. It is strong and has low expansion.

T-1 applications include but are not limited to; models, case molds, and mold backup.


Set-time – 20-30 minutes
Use Consistency – 38-42cc/100 grams
Expansion (max.) – 0.085%
Compressive Strength – 6,000 psi
Dry Density – 103.15 pcf



Sift plaster into water and let soak for 1 minute using a 38 – 42 use consistency.
Mix for no more than 3 minutes


Sift plaster into water and let soak for 1 minute using a 46 use consistency.
Machine mix no more than 2 minutes.

Over mixing can reduce working time, decrease strength and increase expansion. Using a slightly higher use consistency (43-46cc) when machine mixing will help compensate for the additional mix energy being imparted into the slurry.

If a lower use consistency is used when machine mixing, reduce the mixing time and decrease the rpm of the mixer if possible.
