Thioplast G - The Polysulfide

Leading in Performance and Quality

Logo Thioplast-yellow
 

Did you know that polysulfide sealants are the most popular and widely used sealants in insulating glass worldwide? It's the unique combination of chemical and physical properties that make it the industry's first choice.

Thioplast® G, a liquid polysulfide polymer, produced by AkzoNobel in Germany (Greiz) is the leading product used to make polysulfide sealants that save energy and thereby help to reduce climate-changing greenhouse gases.
Polysulfide sealants have excellent adhesive property and gas tightness which guarantee an excellent insulation against cold and heat from the outside to save energy.
Elasticity and pronounced chemical resistance are additional key properties of polysulfide sealants. Thioplast® is therefore ideally suited for the most important application as base polymers for sealants and coatings.

Thioplast® G helps sealant manufacturers fully meet and exceed the uncompromising standards of the aerospace industry. It is instrumental as the functional component in aircraft fuel tank sealants. The product has been the number one choice in this application for over a decade, contributing to the outstanding safety performance of the industry. You'll also find polysulfide based sealants performing exceptionally at gas stations, bridges, facades and runways. Thioplast® G is also used in the production of printing blankets, grinding systems and coatings.

Thioplast® EPS, an epoxy terminated polysulfide polymer with low viscosity, combines the excellent properties of Thioplast® G with those of epoxy resins, including:

  • Excellent adhesion to most surfaces
  • Chemical resistance to many diluted acids, alkalis and solvents
  • Mechanical stability and durability
  • High-speed curing at ambient temperature

Thioplast® EPS is used in adhesives for steel, aluminum, concrete and automotive applications. It also forms important components of anti-corrosive and marine coatings, coatings for chemical plants, as well as mechanically and chemically stressed coatings. Depending on the application, Thioplast® EPS can either be used on its own or in combination with conventional aromatic A/F-glycidyl ethers, novolacs and other epoxies.
