In the modern industrial coatings and printing inks sector, traditional additives often struggle to fully meet production demands when faced with diverse substrates and increasingly stringent process requirements. This product is a multifunctional additive based on specially modified polysiloxane copolymer technology. It is not merely a simple performance modifier but is precisely designed at the molecular structure level to simultaneously address key issues such as substrate wetting, anti-cratering, flow promotion, and defoaming, providing a one-stop, efficient solution for water-based systems.
The core value of this product lies in its exceptional substrate wetting capability. Many low-surface-energy substrates, such as certain plastics, aged coatings, or specially treated metal surfaces, exhibit strong repellency towards water-based coatings, easily leading to uneven application, fisheyes, or cratering defects. This product significantly reduces the surface tension of the system, enabling it to spread rapidly and adhere firmly to these difficult-to-wet surfaces, forming a uniform and complete film. This powerful wetting capability is suitable not only for conventional brushing and roller coating but also adeptly handles high-speed roll coating, spraying, and other production processes with high dynamic wetting requirements, ensuring stable application performance even under high-speed operation.
Regarding cratering prevention, this product demonstrates unique advantages. Cratering often stems from uneven system surface tension or local contamination. Through its unique molecular structure, this product effectively homogenizes the surface tension of the coating film, eliminating local shrinkage caused by differences in substrate surface energy or contaminants like oils, thereby fundamentally preventing the formation of craters and safeguarding the appearance quality and protective performance of the film.
Beyond the two core functions of wetting and anti-cratering, this product also possesses additional properties of promoting flow and defoaming. It improves the leveling of the coating, resulting in a smoother film surface and enhancing the final product's aesthetic grade. Simultaneously, its unique "foam-free" characteristic is another standout feature. During high-speed mixing, spraying, or roller coating, air can easily be introduced into the system, generating bubbles. If these bubbles remain trapped in the film, they can cause pinhole defects. This product effectively suppresses bubble formation and aids in the elimination of existing bubbles, resulting in a dense, flawless coating.
In terms of application scope, this product exhibits broad compatibility and applicability. It can be stably used in mainstream water-based systems such as water-based polyurethane, water-based acrylic, and water-based epoxy resins, without adversely reacting with other components in the formulation, ensuring stability. Specifically, in industrial wood coatings, metal coatings, and plastic coatings, it significantly improves the wetting of complex substrates and the success rate of application; in the printing inks industry, it ensures clear patterns and good adhesion on various substrates, reducing printing defects; in synthetic leather manufacturing, when used for wetting release paper, it ensures uniform coating separation and enhances the surface texture of the synthetic leather.
In summary, this specially modified polysiloxane copolymer additive is a highly comprehensive product. Through a single innovative technology, it simultaneously and efficiently addresses multiple common challenges in the production and application of water-based systems—difficult wetting, susceptibility to cratering, poor leveling, and excessive bubbling. It not only enhances the quality and yield of the final product but also provides robust support for process optimization and efficiency improvements, making it an ideal choice for advancing water-based technology to higher levels of application.
