Polymer Base:

Polyvinyltoluene

Refractive Index:

1.58

Vapor Pressure:

Is vacuum-compatible

Coefficient of Linear Expansion:

7.8 x10 - 5 below +67° C

Light Output vs. Temperature:

at +60° C, L. O. =95% of that at +20° C
No change from +20° C to -60° C

Chemical Compatability:

Is attacked by aromatic solvents, chlorinated solvents, ketones, solvent bonding cements, etc.
It is stable in water, dilute acids and alkalis, lower alcohols and silicone greases. It is safe to use most epoxies and " super glues" with
