Radiation resistant adhesive and coating solutions
A set of alternative solutions and services to existing drilling, welding and sealing with outstanding radioactivity resistance.
Benefits
- Enabling bonding of multiple substrates e.g. stainless steel, concrete, aluminum
- All adhesives and coating available for dry and underwater use
- Durable solution avoiding corrosion and reducing recurring maintenance
- Reduce collective dose (alara principle) by using remote control service to apply adhesive and coating in hard-to-access areas
- Reach conformity and nuclear qualification, approved by european and japanese authorities
- High radiation resistence adhesive material 3mgy (silicone based adhesive) / 10 mgy (epoxy based adhesive)
Issue
Several problems can arise during the manufacturing and maintenance of components, systems and buildings aimed to be used under ionizing radiation:
- Welding is the industry standard for heavy-duty assembly but requires expertise and may not work if the substrates are different (e.g. aluminum to steel). Welds are subjected to corrosion that increases the risk of leakage.
- Bolts allow precise torque control and are removable or replaceable; however, they also require holes to be drilled in the substrate. Screws are commonly used but may not withstand much stress and can be subject to corrosion.
- Rivets are another popular option but require access from both sides to complete the assembly, and they work best with similar substrates.
- Drilling in concrete can influence the durability of the substrate and modify the statics of the building.
- Leakage in hard-to-access areas and underwater areas are difficult to repair.
Today, none of these solutions is fully satisfying for use under radioctive environment.
Solution
We have developed adhesives solutions and services, with multiple benefits as an alternative to the traditional methods. In particular, we can apply adhesive in hard-to-access areas, thanks to a flexible and extendable manipulator system.
Already used in nuclear sector, our radioactive resistant industrial adhesives can flow and conform to the shape of the bond area to fill gaps or to seal a large surface. They provide key benefits over other industrial assembly methods, including:
- Elimination of drilling and holes to reduce labor costs and stress concentration
- Bond dissimilar materials to enable new designs and prevent corrosion
- Bond and seal simultaneously to eliminate process steps
- Coating large or small surface
Our range of adhesives includes:
Epoxy adhesive for strong bonding for concrete and stainless steel (e.g. mounting of construction panels), highly radiation resistant up to 10MGy, heat resistant up to 60°C, high durability, non elastic, useable as coating, self-leveling and suitable for underwater application.
Silicon adhesive for elastic bounds, radiation resistant up to 3MGy, highly heat resistant up to 150°C, high durability, shapeable, shock absorbing, suitable for underwater application.
