Liquid Cement for Splicing Cronar Polyester Cine Films

A. Wasy D'Cruz

The work exploring possible ways to splice Cronar to Cronar using conventional splicing techniques is described. Cronar polyethylene terephthalate film support is chemically inert, presenting major obstacles to conventional splicing. Polyur-ethane mixed with hexafluoroisopropanol and methylene chloride is one typical composition of the new splicing cement, which can be used with standard liquid cement splicing techniques. Satisfactory splices were achieved and, while somewhat slow in attaining full strength, they remained strong and pliable over a range of humidity and temperature conditions. Practical tests made for this bond also are described.
