Definitions
- the present invention generally relates to a system and a method for curing a composition on a substrate.
- the composition comprises an organoborane complex and a radical polymerizable compound.
- OEM automotive finish coatings and aftermarket refinish automotive coatings are two-part compositions that require physical mixing of two condensed phases. This mixing typically limits control of curing, increases cure times, and makes application of the coatings to complex shapes and sequestered surfaces difficult.
- the coatings are applied to automobile parts which are then passed through the ovens to cure the coatings.
- use of the ovens is very energy intensive, expensive, and has an adverse impact on the environment.
- OEM automobile production facilities the ovens occupy large footprints and are cumbersome to use.
- This technology includes use of gaseous atmospheres with UV light and irradiation of coatings in gaseous atmospheres.
- the gaseous atmospheres limit amounts of oxygen that are present during curing thereby limiting oxygen surface inhibition.
- UV and radiation sources used in this type technology are typically disposed at great distances from the coatings such that incomplete curing is reduced but not eliminated. Since radiation sources typically emit large amounts of heat, it is difficult to bring the radiation sources within the gaseous atmospheres and shorten the distances between the radiation sources and the coatings. The heat from the radiation sources causes strong vortexing in the gaseous atmospheres and contaminates the atmospheres with oxygen, thus negating the benefits of using this technology.
- the present invention includes a system for curing a composition comprising an organoborane complex and a radical polymerizable compound on a substrate.
- the system comprises at least one vessel storing the composition comprising the organoborane complex and the radical polymerizable compound and at least one applicator coupled to the vessel for applying the organoborane complex and radical polymerizable compound to the substrate.
- the system also includes a booth having an inlet, an outlet, and a gas sink disposed below the inlet and the outlet.
- a conveyor extends through the gas sink for moving the substrate through the gas sink.
- a gas source is in communication with the gas sink for introducing to the gas sink a displacing gas heavier than oxygen to displace oxygen from the gas sink.
- a controller is in communication with the gas source for controlling the introduction of the displacing gas to the gas sink to control oxygen surface inhibition as the displacing gas decomplexes the organoborane complex for polymerization of the radical polymerizable compound as the conveyor moves the substrate through the gas sink.
- the invention also includes a method of curing a composition comprising an organoborane complex and a radical polymerizable compound on a substrate in a gas sink.
- the method comprises applying the organoborane complex and the radical polymerizable compound to the substrate.
- the method further includes lowering the substrate into the gas sink from the inlet.
- the method also comprises introducing a displacing gas selected from the group of carbon dioxide, sulfur dioxide, sulfuric anhydride, and combinations thereof to the gas sink in a greater concentration than in ambient air to displace oxygen from the gas sink to control oxygen surface inhibition as the displacing gas decomplexes the organoborane complex for polymerization of the radical polymerizable compound.
- the method also includes raising the substrate from the gas sink to the outlet to remove the substrate from the gas sink.
- the displacing gas being heavier than oxygen, the displacing gas settles in the gas sink.
- the substrate is simply lowered into the gas sink from the inlet to decomplex the organoborane complex for polymerization of the radical polymerizable compound.
- the controller controls the introduction of the displacing gas to control the concentration of oxygen in the gas sink to advantageously control oxygen surface inhibition, which can disadvantageously cause incomplete curing of the composition.
- Decomplexing of the organoborane complex in the gas sink allows for the polymerization of the radical polymerizable compound at room temperature without the need for UV light, curing ovens, etc. This greatly reduces production costs, complexities, and times, decreases a number of synthetic steps required, and increases product yields and concentrations. In addition, this reduces a carbon footprint of the instant invention and saves energy.
- the organoborane complex also allows the composition to rapidly cure at reduced temperatures and to bond to various substrates, including low energy substrates. This increases production efficiency and speed and further reduces production costs and energy expenditure associated with heating and/or using radiation for curing.

Abstract
L'invention porte sur un système pour durcir une composition, lequel système comprend une cabine ayant une entrée, une sortie et une évacuation de gaz. La composition comprend un complexe organoborane et un composé polymérisable radical, et est appliquée à un substrat. Le système comprend un transporteur s'étendant à travers l'évacuation de gaz pour déplacer le substrat à travers l'évacuation de gaz. Une source de gaz est en communication avec l'évacuation de gaz pour introduire dans l'évacuation de gaz un gaz en déplacement. Le gaz en déplacement est plus lourd que l'oxygène, de façon à déplacer l'oxygène à partir de l'évacuation de gaz. Un dispositif de commande est en communication avec la source de gaz pour commander l'introduction du gaz en déplacement vers l'évacuation de gaz. L'introduction du gaz en déplacement est commandée de façon à commander une inhibition de surface d'oxygène lorsque le gaz en déplacement décomplexe le complexe organoborane pour la polymérisation du composé polymérisable radical lorsque le transporteur déplace le substrat à travers l'évacuation de gaz.
