Rimlex Underhead Sealants
The Anochrome Group is able to offer a proprietary product called Rimlex®, together with a range of other flexible organic non-reactive materials, for sealing underhead fasteners, rivets and other components requiring gaskets. They can also be used in conjunction with thread sealants and locking patches applied by the Anochrome Group application centres at Inlex Locking Ltd in Wolverhampton and Anocote Ltd in the Czech Republic.
Rimlex is a peripheral seal, which can be applied to the underhead bearing surfaces of bespoke fasteners, or other suitable components. Rimlex can replace copper, aluminum and other more expensive sealing washers. When components are assembled, the material is forced into any gaps between mating surfaces to form a robust seal. Different grades of the material exhibit various properties, but fuel, oil, brake fluid and antifreeze resistant sealants are available. Some varieties exhibits excellent re-use capabilities, and even when under torsional pressure, will seal after 12 or more re-uses. In most cases Rimlex does not significantly alter torque tension characteristics of threaded components.
Rimlex, and other seals or gaskets such as Dymax 482 or Precote® 15, is applied using computer controlled multi-axis dispensing equipment. The equipment can produce complex shaped gaskets on a variety of components. Gaskets can be a variety of heights, shapes and sizes as a gap filling self-levelling bead or with a low slump convex profile.
Visual and dimensional checks can be made using either laser or visual measurement equipment. The height and positional accuracy can be measured automatically at a number of points on the bead profile to an accuracy of 0.001mm.
The interface geometry of mating components is critical to correct functioning and reuse of the Rimlex seal. The mating hole, as a minimum, should be burr free, chamfered and/or engineered to ensure Rimlex material is not stripped or cut away during installation. In most cases an SAE J2244-1 (ISO 6149-1) hole form is suitable.
To meet torque/tension requirements, the Rimlex seal co-efficient of friction can be modified with the addition of materials such as TT15®.
The products can be readily applied to most electroplated finishes as well as aluminum, brass, stainless steel and organic coatings. Some room temperature cure materials are suitable for GRP(glass reinforced plastic) and plastics.
