Thioplast G21F

Thioplast - polysulfides

This grade´s unique combination of strength, elasticity, weatherability and gas tightness makes it the industry's first choice for insulating glass sealants. Formulators tailor properties like pot-life, tensile strength, adhesion and elongation at break by choosing from various compatible plasticizers, fillers and other additives. The viscosity, degree of branching and SH content can easily be adjusted by blending this grade with others to generate your tailored Thioplast polysulfide.
