SUBJECT: Perm Rating of Indurall Sample Protecto 401

Procedure A of ASTM 96-66, described in Project 10-002 p 14-30 (February 1979), was used to determine the permeance of the submitted paint sample. Over a period of thirty days in our humidity cabinet, relative humidity (outside the cup) and temperature averaged 48.6% and 78.0 °F (25.6 °C), respectively. Glidden’s Insul-aid was used as the control in this test. The permeance of the Protecto 401 (Q8-2401 [component A] blended with D8- 2401 [component B]) along with the control are shown in the following Table:
