PR3 glueing work at Kashiwa

Members: Tatsumi-san, Manuel

Before making the glueing work it is necessary to pour First Contact polymer on the central area of mirror surface. We tried to do that but we had some troubles. I attach the pictures to show the problem. If the flow from the bottle is not continuous, the liquid splatters around and so we got some droplets in the area which is not to be covered by FirstContact. So we had to add FirstContact on the droplets and peel it up to clean them. The droplets went also on the edge and we had to apply the FirstContact with a brush. and using a smaller bottle.
