Rope Caulk is a sealant which is designed primarily as an allpurpose weatherstripping for use around windows and door frames, etc. It can be prepared and extruded only in heavy duty type of equipment. The selection of the ingredients and the ratio in which they are used have to be carefully made to achieve the necessary properties. Rope caulk must be non-drying, have good adhesion to surfaces and also have sufficient strength after extruding so that it will maintain its rope form even after much handling. For best results the ingredients should be added in the order given and the mixing continued for some time after the pigments have been added so as to insure complete and uniform incorporation Petrolatum/45 lb "SNOWFLAKE" WHITE/450 soya Fatty Acids/8 lb "TiPure" R-510/25 lb "Indopol" H-1500/379 lb 5-R Asbestos Fiber/475 lb
