Low Toxicity Sealants Used to Join Stiff Supports

摘要

Polysulfide sealants are products based on aliphatic polymers,which are classified as elastomers (rubbers).The subject of this paper is two pack polysulfide sealants.Two pack polysulfide sealants have as main constituents:polysulfide polymer included in the so called A component;oxidative agent included in the so called B component.The sealant results by mixing these two components in a certain mixing ratio at normal temperature by polymerization.
