Early adhesive uses of butyl rubber generally consisted of solvent-based dispersions, or tape and rope extrusion of formulated solid rubber. Extensive use was made of butyl rubber s inherent tackiness in highly saturated grades of the polymer to make pressure sensitive tapes and precoated films. The polymers are also extensively used as major components of hot-melt adhesives, solid rubber sealing tapes, and caulking grades of sealants and mastics, of which most were high solids content solvent-based formulations. 

After the slotted grids have all been installed, they should be pushed toward the center of the converter and fitted together so that it is not possible for any of the 1/2" quartz pebbles to fall through. Then two or three strands of insulating rope may be used to caulk around the shell of the converter. No caulking should be used between e slotted grid sections as they must be placed to allow for some expansion. 

The solid partition plates must be carefully caulked between each plate and between the plates and the converter shell with several strands of insulating rope. It is extremely important that no gas be able to pass these solid partitioa4)lates. Gas leaks past these solid partition plates will cause poor temperature control and result in loss of conversion efficiency. 

The use of adhesives and sealants dates back thousands of years. The ancient Egyptians used giun arabic and animal glues for bonding papyrus reeds and veneering finniture (Dick, 1987). For several hundred years the crevices between the wooden planks of boat hulls have been caulked with rope and pitch to prevent water leaks.
