Abstract

The use of benzoate plasticizers in two-component insulating glass adhesives/sealants based on polysulfide polymers or polymercaptan polymers enables simpler production due to the low viscosity thereof. Improved miscibility of the two components and an improved rate of curing are observed. In addition, the use of phthalate plasticizers, which may possibly cause an endocrinal effect in humans and animals, is avoided.
