ALPHAMAT TECHNICAL SPECIFICATIONS

Furnish: Alpha-cellulose fiber which meets the most stringent standards for stability and permanence.Tests conducted in accordance with TAPPI  Method T-401 OS-74 indicate the board to be free of groundwood and  lignin.
PH Value: An alkaline pH of 8.9 +/-.4 indicated using TAPPI Method T435.
Buffer: Tests conducted by Atomic Absorption Spectroscopy reveal a minimum content of 3% Calcium and Magnesium  Carbonate buffers.
Molecular  Traps: Contains molecular traps  synthesized specifically for adsorption of air pollution gases and  degradative by-products of artwork and photographic media.
Color  Fastness: Fade resistance established using a Carbon Arc type Fade-O-Meter in accordance with ASTM G-25  for 20, 40, 60 and 80 hours. Alphamat colors shifted less than 2.5 points of brightness after exposure.
Bleed  Resistance: No bleed visible  after 48-hour submersion in distilled water.
Resistance to Aging: Samples tested in  an air circulating oven for 12 days at 100 degrees C and for 10 days  in temperature humidity chamber at 100 degrees F and 90% relative humidity. All board components remained unchanged in appearance and strength.
Sizing & Adhesives: Alkaline-based  sizing is used. Water-based alkaline adhesive with no solvents is used to adhere component parts of Alphamat boards.
Meets  and exceeds FACTS guide for mat and mountboards.
