ABSTRACT

The stimulus for the above extra research effort can be cited in a variety of factors which affect the manufacturing reproducibility and economic costs. It should be obvious that when two or more reactive liquids or paste combinations must be mixed shortly before use that increased production costs are necessarily involved in the metering, mixing, and degassing of the separate components. Further, as the pot-life of the multiple mix materials becomes shorter, the possibilities increase for premature thickening or gelling before adequately wetting the surface. All these factors can significantly reduce the reliability of finding consistently strong and equally durable joints in service.
