Hockmeyer’s rapid flow and recirculation technologies play a crucial role in the dispersion process, ensuring the consistent and tight particle size distributions that are vital for maintaining high product quality in paper coatings. Machines like the HCP Immersion Mill, the HHL line of dispersers/mixers, the HCP Immersion Mill, and the HVI Hoist Mounted Disperser are all great options for manufacturing paper coatings. Furthermore, Hockmeyer’s innovative equipment improves efficiency, overall operational effectiveness, and productivity by drastically reducing process times.

Yes! We understand that the process of finding the right equipment can be challenging, so we have equipped our testing facility with laboratory and scalable pilot models of our most popular offerings. We also offer free initial testing to help you evaluate the performance of the equipment and find the paper coatings solution that best fits your needs.

Coatings are applied in layers of different substances to improve qualities like printability, smoothness, gloss, and durability, and the paper coating process is vital for enhancing the finished product’s properties and performance for specific uses. The process involves several steps, including coating formulation preparation (mixing pigments, binders, additives, and solvents to create a coating mixture), mixing and dispersion to ensure a uniform mixture to prevent clumping or settling, and applying the coating using methods like roll coating, blade coating, air knife coating, or size press coating based on thickness, paper type, and formulation. The process is completed through drying or curing, which removes solvents and enhances binder adhesion and durability through drying or chemical reactions.

Particle coating methods are vital in paper coating manufacturing, providing various techniques for enhancing paper properties and achieving specific effects on the paper’s surface. Air knife coating uses controlled air to deposit particle-laden fluid uniformly onto the paper. This method ensures even coatings with controlled thickness. In press coating, the paper passes through a particle-laden liquid bath that enhances properties like smoothness and printability. Spray coating involves dispersing particles in liquid and applying the mixture with precision. This method is versatile, allowing for textured surfaces and visual effects. Gravure coating employs engraved rollers to transfer the coating, providing high-quality, consistent fine coatings.

Other methods include offset printing with dry powder, which modifies offset presses to apply powders, adding specific visual effects to printed materials. Electrostatic coating charges particles and applies them using an electric field, a process that is useful for toner-based printing and textures. Finally, hot melt coating melts solid coatings, applying them as a fluid that solidifies upon cooling, serving various applications.
