Simrit develops solutions for abrasion and friction issues in aerospace applications

Simrit today announced that it will showcase its material and coating innovations that address abrasion and friction issues in critical aerospace applications during the 49th International Paris Air Show. Simrit, a global supplier of customized material and technology solutions for the aerospace industry, will demonstrate its new low-temperature polyurethane material and low-friction coating process during the show that runs from June 20 to 26 in Le Bourget, France.

"Our friction and abrasion solutions offer reduced friction and greater abrasion resistance for lower cost while providing improved sealing versus other solutions," said Vinay Nilkanth, vice president global sales aerospace, Simrit.

To address abrasion concerns associated with such things as aerodynamic seals, Simrit developed the low-temperature polyurethane solution. Offering a brittle point of minus 59 degrees Celsius, this 70 durometer, high-tensile material has a tensile strength of 4,000 pounds per square inch. The Tear Die B (300 pixels per inch) material also demonstrates superior adhesion and bonding to substrates and elongation in excess of 400 percent.

During the show, Simrit will also showcase its low friction / low static coating for door seals and low pressure dynamic seals, as well as applications where "nipping" occurs. The new coating dramatically reduces surface friction and stiction to silicone rubber. The coating offers excellent cohesion to silicone substrates and release properties, and can be easily applied to finished components. Unlike traditional coatings, Simrit's solution does not affect the "sealability" of the silicone surface and can be incorporated for minimal cost on existing components.

As an example, an emergency exit door seal was nipping on closure due to friction. The solution was to add the coating and this successfully eliminated the nipping, but did not reduce the sealability.
