Hi,Mike !!!
Here are the specifications apply to both the rubber 70 shore and 90 shore
TECHNICAL
Before Catalysis
Appearance component A thick liquid beige
Appearance component B: transparent thick liquid
Specific gravity A + B: 1.200 kg. / Lt.
Viscosity A + B: 2200 CpS
Mixing ratio: 1:1 by weight
During Catalysis
Workability time (pot life): 30-35 minutes
Demoulding time: 24 hours
Full cure: 72 hours
It is recommended to avoid catalysis of the product at temperatures above +30 ° C
After the Catalysis
Appearance: beige rubber elastic
Tear strength: 43 N / mm (very high)
Elongation at break: 600% (high)
Linear shrinkage after 5 days. (ISO 4823): <0.1%
For coloring the product can I use powder pigments or aniline greases, adding the dye to the first component A ?
