Sonderhoff’s Fermapor K31 product line creates a barrier gasket to protect industrial assemblies from contaminants.

US-based system supplier of sealing, gluing and potting solutions, Sonderhoff, has introduced the product line Fermapor K31, a two-component, crosslinking polyurethane formed-in-place (FIP) foam sealant.

Fermapor K31 is designed to create a barrier gasket that protects industrial assemblies from moisture, dust, dirt, liquids and other contaminants. Formulated to conform to highly intricate metal and plastic components, the technology effectively seals electrical and electronic housings, lighting enclosures, appliances, automotive components, and other contaminant-sensitive consumer and industrial assemblies.

Two-component Fermapor K31 cures at room-temperature when its resin and hardener are mixed during the dispense process. Ovens are not required, but heat will accelerate cure. The cured gasket operates reliably in temperatures from -40º to +100º C and can withstand up to 160º C for short durations. The material meets REACH/EC 1907/2006 and RoHS standards.

Once applied, Fermapor K31 expands to its full size in seconds, so process-oriented quality control systems can determine whether the seal has achieved its required height over the entire contour. The sealing foam adheres to and seals many different substrates and shapes and provides 100% contact between mating parts.
