2、 name and type of sealant; 7.3 Testing of multi-component sealants c) batch of sealant and age, if possible; Place 500 ml of deionized or distilled water in the graduated glass cylinder (5.3) and read the level of water. Then extrude approximately 50 ml of the sealant from the extrusion device (5.1)
3、 into the water and record the time required. Read and record the level of water for its exact volume. The first extru- sion shall be performed 15 min after beginning of the mixing of the components. Repeat the procedure at least three times, that is, extruding ap- proximately 50 ml each time and re
4、cording the time required and the exact volume. Using the time required for each volume of sealant at suitable intervals of time, develop a volume/time graph so that a curve can be plotted which shows the extruded volume per minute at any time within the application life of the sealant as specified
