Advances in One Part Polysulfide Sealant Technology

Source

One of the major drawbacks of one part polysulfide sealants is their extremely slow cure rates compared to other types of sealants.

Major studies have been conducted in an effort to find ways of accelerating the cure of one part polysulfide sealants. New formulating techniques and new developments in curative technology have shown that one part polysulfide sealants can be formulated that have cure rates similar to other generic types of sealants while maintaining good shelf life stability.

Sealants will be discussed that have been formulated based on these studies. These sealants have been tested and found to meet all the requirements of ASTM C-920.
