Low-dust joint compound composition with dust reduction additive
A recently granted patent (Publication Number: US12000158B2) discloses a low-dust joint compound composition designed to reduce dust generation during sanding. The composition includes a dust reduction additive emulsion containing colloidally-protected wax-based microstructures and a first water component. The wax core of the microstructure consists of a paraffin component and a non-paraffin component, while the polymeric shell includes various polymers such as polyvinyl alcohol. Additionally, the composition may contain fillers, binders, thickeners, non-leveling agents, preservatives, rheology modifiers, and surfactants to enhance its properties.
Furthermore, the patent details methods for using the low-dust joint compound composition, including applying it to wallboard panels, allowing it to dry, and sanding the dried compound. Another method involves adding the dust-reduction additive emulsion to an existing joint-compound composition to reduce dust generation during sanding. The goal is to achieve a significant reduction in dust production, with claims stating reductions of at least 5% and up to 80% in dust quantity. The composition's unique formulation aims to improve the overall sanding experience and reduce airborne dust particles, enhancing safety and cleanliness during construction activities.
