Sealants and adhesives

Thioplast^® G polysulfides a liquid polysulfide polymer, is the leading product used to make polysulfide sealants and help manufacturers fully meet and exceed the uncompromising standards of the aerospace industry. 
 
Polysulfide sealants have excellent adhesive properties and gas tightness which guarantee superior insulation against cold and heat from the outside to save energy. Elasticity and pronounced chemical resistance are additional key properties of polysulfide sealants. 
 
In addition to the aerospace industry, you find polysulfide-based sealants performing exceptionally well at gas stations, bridges, facades, and runways. 
 
In our portfolio, we also have the Thioplast^® EPS polysulfides product line. An epoxy terminated polysulfide polymer with low viscosity, which combines the excellent properties of Thioplast^® G polysulfides with those of epoxy resins. Thioplast^® EPS polysulfides is used in coatings and adhesives on various substrates such as steel, aluminum, and concrete, across a variety of applications including aerospace, automotive and construction.

Adhesives offer many advantages over other binding techniques. They facilitate the binding of different materials, distribute stress across the joint more efficiently, improve the esthetic outcome and they increase design flexibility. 
 
Depending on the specific application our Levasil^® CT products can be added to improve heat resistance and shear strength and to reduce drying time. In addition, colloidal silica can be used to adjust the viscosity of adhesive formulations, without needing additional thickeners.
