Thioplast® Polysulfides in Adhesives

Adhesives: Key to Advanced Engineering

In the realm of modern industry, where precision, reliability, and efficiency reign supreme, the role of adhesives has transcended mere binding agents to become foundational pillars supporting a myriad of applications. At the heart of every industrial innovation and high-performance undertaking lies the critical contribution of adhesives - the unsung heroes that enable the seamless fusion of materials, the fortification of structures, and the realization of groundbreaking designs.

Boding surfaces where it matters
Within adhesive materials, Thioplast polysulfide-enhanced epoxy adhesives occupy a unique space due to their specialized properties that are tailored for challenging applications and environments. Incorporating Thioplast polysulfide compounds into epoxy systems results in modifications that extend the capabilities of these adhesives. These formulations are widely used where durable and protective qualities are paramount, such as in aerospace, electronics, and other specialized manufacturing sectors.

Thioplast polysulfide-based epoxy adhesives offer a range of benefits that make them highly suitable for various industrial applications. Understanding their key properties can help you choose the right adhesive for specific needs.

Adhesives are essential in modern industry, streamlining the assembly of complex products and enhancing their strength and durability. Their versatile applications reduce costs and enable the use of diverse materials.

 

Key Properties

 

 

Mechanical Strength: Tensile and Peel Strength
Polysulfide-epoxy adhesives are known for their impressive mechanical strength, heavily influenced by the bond substrate and the adhesive's formulation.

  • Tensile Strength: optimal tensile strength is typically achieved with a polysulfide content between 10-30%.
  • Peel Strength: Certain formulations can reach peel strengths up to 3.5 N/mm, providing a robust bond that effectively resists peeling forces.

Heat Resistance
The heat resistance of these adhesives is influenced by the proportion of polysulfide. A moderate proportion, roughly 20%, results in minimal impact on the heat distortion temperature. However, when polysulfide and epoxy are in equal ratios, there is a significant reduction in thermal resistance, restricting the adhesive’s use in high-temperature applications.

Shear strength increase with and without Thioplast EPS 35 Polysulfides on various surfaces.

 

 

Chemical Resistance and Environmental Adaptability
Thioplast polysulfide-epoxy adhesives exhibit excellent resistance to chemicals and environmental conditions, making them suitable for demanding industrial settings:

  • Chemical Resistance: These adhesives can withstand various chemicals and solvents, even under immersion conditions.
  • Water and Corrosion Resistance: Thanks to their low water and water vapor permeability, these adhesives provide superior water and corrosion resistance.

Cure Shrinkage and Low-Temperature Performance
Polysulfide-epoxy adhesives offer minimal cure shrinkage and excellent low-temperature performance. The low cure shrinkage reduces distortion of bonded parts upon curing, unlike traditional epoxy resins. Additionally, these adhesives maintain their integrity and performance during thermal shock and cycling, making them ideal for environments with temperature fluctuations.

These adhesives maintain integrity and performance during thermal shock and cycling, making them ideal for environments subject to temperature fluctuations.
