  • Publication number: 20250101277
    Abstract: Commercially available waterbased adhesives can be used to adequately secure unmodified TPO roofing membrane to a roof substrate only by using a two-sided (contact bond) application. Alternatively, commercially available waterbased adhesives may be used a single-sided application using TPO membrane that is modified at manufacture with an additional backing (“fleece back”). Disclosed herein is a water-based adhesive formulation that will bond unmodified TPO membrane to the roof with a one-sided application, saving money and increasing productivity. The disclosed adhesive is applicable by high pressure canister application, facilitating the efficiency of its use.

  • Patent number: 12259711
    Abstract: An example monitoring system for data collection includes a data collector including a plurality of sensor. The system includes a data storage to store a collector route template for the plurality of sensors with a sensor collection routine defining how the plurality of sensors. The system includes a data acquisition and analysis circuit to receive detection signals and evaluate the detection values with respect to a rule, and further, based on the evaluation of the detection values with respect to the rule, to modify the sensor collection routine.

  • Patent number: 11866617
    Abstract: Adhesive compositions are described that are suitable for securing building materials, such as TPO membrane roofing to a structural element, such as a roof deck. The adhesive compositions are very high-solids, wet-set adhesives that provide a peel strength that meets or exceeds industry standards, while requiring application to only one of two surfaces to be joined. The adhesive compositions comprise a liquid modifier with hydroxyl functionality, a chlorinated polyolefin and a silylated polymer. Methods of use are also disclosed.
