Introduction
In the vast landscape of the coating and ink industry, the quality and performance of the final product are significantly influenced by the additives used. Among these additives, wetting agents play a crucial role in ensuring that the coating adheres well to the substrate, spreads evenly, and exhibits a smooth finish. Wetting agent IOTA 245 has emerged as a game - changer, offering a unique set of properties that make it a preferred choice for a wide range of applications.
Product Overview
Wetting agent IOTA 245 is a remarkable chemical compound, specifically a polyether - modified silicone oil. This composition endows it with a combination of properties that are highly desirable in the coating and ink sectors. Its appearance ranges from colorless to light yellow liquid, which is not only aesthetically pleasing but also indicates its purity and quality. With an effective content of over 99.8%, it is a concentrated and potent additive.
Technical Indicators: The Building Blocks of Performance
Appearance
The colorless to light yellow liquid appearance of IOTA 245 is not just a matter of visual appeal. It also serves as an indicator of its purity and manufacturing quality. A consistent and clear appearance reflects the absence of impurities that could potentially affect its performance in the coating or ink system.
Effective Content
The high effective content of >99.8% is a testament to the product's potency. This means that a relatively small amount of IOTA 245 can have a significant impact on the properties of the paint or ink. It ensures that the active ingredients responsible for wetting, leveling, and other beneficial effects are present in sufficient quantities to deliver optimal results.
Specific Gravity
With a specific gravity in the range of 1.025 - 1.049g/cm³, IOTA 245 has a density that allows it to blend well with different paint and ink formulations. This property is crucial for ensuring uniform distribution of the wetting agent throughout the mixture, which in turn is essential for consistent performance across the coated surface.
Refractive Index
The refractive index of IOTA 245, measured at 25℃ and falling between 1.449 - 1.451, provides insights into its optical properties. This parameter can influence the appearance of the final coating, especially in terms of its transparency and gloss. In applications where a clear and shiny finish is desired, such as in water - based light oils or certain types of coatings, the refractive index of IOTA 245 plays a vital role.
Viscosity
The viscosity of IOTA 245, ranging from 10 - 100cP at 25℃, is another key factor. It determines how easily the wetting agent can flow and mix with the paint or ink. A relatively low viscosity allows for better dispersion, ensuring that the IOTA 245 can quickly and effectively interact with the other components of the formulation. This is particularly important during the manufacturing process and when applying the coating, as it helps to prevent clumping and ensures a smooth application.
Cloud Point
The cloud point of IOTA 245, which lies between 50 - 60℃, is significant in terms of its stability in different temperature conditions. Above the cloud point, the wetting agent may start to separate or become less effective. However, within the normal operating temperature ranges of most coating and ink applications, IOTA 245 remains stable, maintaining its excellent wetting and leveling properties.
Solubility
The fact that IOTA 245 is soluble in water is a major advantage. It enables its use in a wide variety of water - based coating and ink systems, which are becoming increasingly popular due to their environmental friendliness. Water - based formulations are often preferred over solvent - based ones as they emit fewer volatile organic compounds (VOCs). IOTA 245's water solubility makes it an ideal additive for these systems, without sacrificing performance.
