Automated UV Bonded Gaskets

Adhesive technologies to assemble large or complex gaskets that meet demanding applications

Stockwell Elastomerics is committed to bringing the best performing materials to OEMs, giving them the competitive edge. Large gasket applications often use sub-par materials due to cost restrictions and wastes associated with traditional cutting. In 2013, Stockwell Elastomerics made a capital investment in a custom, automated ultraviolet (UV) bonding system. This automated process, combined with four in-house waterjets and CNC die cutting, allows for precision bonded gasket joints. UV jointed gaskets offer the benefits of single piece gaskets with additional cost savings.

At a Glance: Benefits of UV Bonded GasketsWhite and red sponge gaskets with monel wrap along the inside edge

  • Bonded corners for sealing against IP64, IP65, IP66, NEMA 4X
  • Cost savings for large gaskets
  • UL 50E recognized gasket materials
  • UL 94 flame rated materials available
  • Excellent memory and compression set resistant
  • Closed cell materials for ingress protection
  • UV and ozone resistant gasket materials
  • Flexible and seal at very low temperatures (-70°F)

Best Gasket Material for Enclosures

Silicone, closed cell silicone foam and closed cell silicone sponge are considered the best enclosure gasket materials. Silicone has excellent long term memory known as compression set resistance – meaning it continually rebounds after being compressed. Stockwell Elastomerics’ silicone foam and silicone sponge materials are UL 50E gasket materials, good for NEMA enclosures. UL 94V-0 recognized gasket materials are also available where flame rating is needed (e.g. gasket for T8 LED fixtures).

Industries Using Automated UV Bonded Gaskets from Stockwell Elastomerics

  • Telecom – base station NEMA enclosures
  • Remote Monitoring – measuring equipment in desert and Arctic
  • Military – globally deployed enclosures and aerospace
  • Digital Displays and Kiosks –environmental gaskets and spill gaskets
  • LED Signage – ingress protection meeting UL 48
