What is a Stouffer Scale and how does it work?
The best exposure test for basic exposure hardness is a Stouffer 21-step Transmission Gray Scale, a 5.5″ camera film positive opaque at one end, and clear at the other with 21 steps in between. The 21 steps simulate 21 different exposures, and you get visual feedback to make clear judgments without guessing.
With the Nova PT™ series a solid 15 to 16 should be obtained. With the Exterior material, a solid 12 to 13 should be obtained.
Can you cut metal and plastic with the shear I purchased?
In order to cut metal and plastic, you would need a separate metal cutting blade (upper and lower).
What substrate options do I have with exterior polymer?
We offer an aluminum 20″x30″ sheet or a 22″x26″ steel sheet. Learn more about our exterior polymer, Novacryl® EX™ Series.
