Abstract: A high performing low viscosity tire sealant includes about 15% to about 75% by weight of a biobased aliphatic diol, about 5% to about 50% by weight natural rubber latex, and about 2% to about 50% by weight synthetic rubber latex. The tire sealant exhibits excellent performance at temperatures of -40 degrees Celsius and lower.

Abstract: A two part adhesive formulation is provided that is REACH and RoHS compliant and cures at room temperature of 23 degrees Celsius at 1 atm. The two part adhesive has a first component part (component A) that is a resin that is a blend of epoxy and modified epoxy resins with fillers, thixotropes, solvent, and colorant, and a second component part (component B) that is a curative that is a blend of amines, fillers, solvent, and colorant. A toughening agent and an impact modifier is in at least one of the adhesive part or the activator part, part B. The adhesive formulation is designed with the right balance of viscosity and thixotropic behavior to enable seamless dispensing through a micro-orifice in an auto dispenser that is used for application of adhesive on to magnetic elements or other electronic or microelectronic components.
