Polysulphide Sealant Metering for Aerospace

Polysulphide sealants protect aircraft structures and fuel tanks. They are thick, two part and unforgiving of ratio errors. Specialist shot metering gives the control and repeatability these critical sealing jobs demand. Rockingham Systems are sole distributors for Nordson sealant equipment in the UK, Ireland and Benelux. The Pro-Meter H2K, A2K and D2K and the Micro-Meter P2K, A2K, D2K and 1K cover everything from heavy duty shots to tiny precision doses. Positive rod displacement metering proportions both materials to an exact volumetric ratio every stroke. Abrasive and heavily filled products that wear out other pump types are handled without losing ratio. Common materials include two part epoxies and polyurethanes for bonding and potting, silicones for gasketing and sealing, MMA for fast structural bonds, and filled thermal compounds for heat management. Rockingham Systems will review the application, the material and the target output, then recommend equipment that fits the job and the budget, rather than selling the biggest machine on the list.

Get the mix and the dose right and everything downstream gets easier. Fewer failures in test, fewer returns and less time cleaning up. Rockingham Systems provide installation, training, spare parts, on and off site servicing and ongoing technical support. Call the UK sales team on +44 (0) 1536 628 734.
