The adhesive used on the Weatherproof Direct Thermal material is a rubber-based adhesive. If you are looking for an acrylic-based adhesive, I would suggest our Standard White Direct Thermal material. The Standard White Direct Thermal material, however, is not considered weatherproof and would not be recommended for applications that expose it to moisture.
