Optimal Selection of Leveling Agent for Paints and Coatings - koipdd66 - 03-04-2022
Dyeing auxiliaries are defined as chemicals or formulated chemicals which enables a processing operation in dyeing to be carried out more effectively. Dyeing auxiliary includes dye fixing agents, cationizing agent, dispersing & leveling agents etc. They help in stabilizing the dyeing bath to improve the exhaustion, achieve level dyeing and improve fastness properties.
Need for Leveling Agents
It is admitted for many paints that a perfect appearance means also a perfect leveling. Poor leveling (like orange peel or ghosting) may not influence significantly the paint parameters in time, as it is more aesthetic orientated. But the leveling agent itself may cause some severe issues.
A correct leveling agent helps in reaching the wanted leveling and final film finish. But a wrong choice may lead to surface defects such as craters, pinholes, loss of gloss or even inter-coat adhesion problems. Therefore, to understand the leveling, it is important to understand the influence of the surface tension on the paint and finding a balance is critical:
Acrylic resins feature excellent transparency and durability, and are used in a broad range of applications from consumer items like lenses to industrial products like molding materials, coatings and adhesives.
About Acrylic Resins
Acrylic resins feature excellent transparency and durability, and are used in a broad range of applications from consumer items like lenses to industrial products like molding materials, coatings and adhesives. In addition, acrylic resins are also used in other areas, such as binders for paper/fiber processing, PC screens, display windows for cellular phones and light guide panels for liquid crystal display (LCD) backlights.
Due to their excellent durability and weatherability as coating materials, acrylic resins are used extensively in applications such as automotive, architectural and plastic coatings.
Acrylic resins have the below general characteristics.
WHAT IS THE DIFFERENCE BETWEEN A DEGREASER AND A CONTACT CLEANER?
Degreasers are intended to remove oil, grease, oxides and handling contamination from equipment and assemblies, while a contact cleaner does the same thing specifically for electrical contacts.
A contact cleaner (also called electrical cleaner, switch cleaner, electrical contact cleaner, and (specific for automotive repair) battery terminal cleaner removes contamination from electrical contacts, the conductive surfaces of connectors, switches and other electrical and electronic components with moving surface contacts.
