Adhesive gasketing solutions for industrial flanges and joint faces

      Master adhesive gasketing for rigid and flexible joint faces

Even the slightest failure on a flat gasketing joint can cause critical leaks, lead to industrial contamination, and compromise the safety of your equipment.

The result: reduced efficiency, unplanned downtime, and rising maintenance costs.

Ensuring reliable and durable gasketing on your rigid or flexible joint faces is essential to maintain the performance and continuity of your industrial operations.

Why choose an adhesive gasketing solution?

Our adhesive gasketing solutions provide key benefits:
 

➡️ Eliminate re-tightening operations
 

➡️ Prevent corrosion risks on joint faces
 

➡️ Reduce productivity losses related to sealing issues

Choosing an adhesive gasketing solution ensures a reliable, easy-to-apply, and long-lasting barrier to secure your equipment.

      The 5 main causes of traditional gasket failures

👉 The 5 main causes of traditional gasket failures

❌ Compression set (creep or relaxation)

Traditional gaskets lose thickness over time, leading to leaks and requiring frequent re-tightening.

❌ Surface irregularities

Incomplete contact between the gasket and the joint face creates leak paths.

❌ Gasket displacement

Insufficient compression under high internal pressure can lead to gasket movement and sealing failure.

❌ Joint face deformation

Differences in thermal expansion coefficients between materials cause warping, resulting in leaks.

❌ Gasket extrusion

Under mechanical stress, traditional gaskets can extrude, reducing sealing effectiveness.

👉 Advantages of liquid gasketing solutions

✅ Fills micro-gaps and surface irregularities
 

✅ Eliminates seepage risks
 

✅ Resists vibrations and mechanical shocks
 

✅ Reduces inventory and maintenance costs
 

✅ Improves equipment safety and reliability

      Which product for your application?

The choice of flat gasketing product directly depends on the type of joint face and the mechanical and environmental constraints of the application.

      Surface preparation

Components must be clean and free from impurities such as grease, oil, gasket residues and other sealing products.

Degrease, clean and dry the parts before applying the product.

👉 Discover our complete selection of industrial cleaners and degreasers.

For maintenance and repair operations, remove old gasket residues using a dedicated remover, then clean the surfaces with an industrial degreaser.

If the gasketing product is applied at a temperature below 5 °C, pre-treat the surfaces with an activator.
