Tim Pione, vice president, Advanced Packaging and Converting, Adhesives, at Arkema discusses the company’s pressure-sensitive adhesive products, including hot-melt, waterborne, UV, and specialty solution acrylics technologies.
Self-adhering flashing tapes work in concert with products like roof underlayment and water-resistive barriers (commonly called housewrap) to help ensure that a structure’s building envelope can maintain the desired interior environment while providing protection from elements outside. To that end, flashing tapes effectively serve as gaskets that are used around the fenestration, air vents, and pipe penetrations that are common culprits for moisture ingress and air movement.
Newly developed UV-activated, dual-cure silicones can protect sensors in autonomous vehicles from the heat, cold, moisture, and stress that result from the rigors of the automotive environment.
May 11, 2022
Automobile manufacturers have identified approximately 200 sensor areas around the vehicle that will be instrumental in achieving commercialization and meeting safety goals for autonomous vehicles. The main commonality is the need to protectively seal these key sensor platform areas from the heat, cold, moisture, and stress that result from the rigors of the automotive environment.
A new solution has been developed in the form of pre-dispersed masterbatches of core-shell particles in (meth)acrylate monomers. These new liquid toughener dispersions are stable and have been proven to increase the toughness of acrylic materials. The utility of these tougheners has been demonstrated in light-curable thermoset formulations and in 2K acrylic structural adhesives.
