ASTM C736 Standard Test Method for Extension-Recovery and Adhesion of Latex Sealants
ASTM C736 covers a laboratory procedure for the determination of the extension-recovery and adhesion of latex sealants.
This test method evaluates the performance of a latex sealant in joints subjected to a limited amount of extension
Summary of Test Method
A joint of prescribed dimensions, between glass and aluminum plates is filled with the sealant.
After an aging period, the joint width is increased 25 %, the force is removed, and the specimen is permitted to recover.
The amount of recovery and the percent of adhesion loss are measured.
Apparatus
Extension Machine that can be operated at a steady rate of 12.7 mm/min (0.5 in./min) and held at constant extension for 5 min.
