Superior Substrate Wetting and Penetration

One of the most outstanding features of IOTA 245 is its low surface tension. This property allows it to quickly spread and wet the substrate, ensuring good adhesion. Whether it is a porous surface like wood in water - based wood coatings or a smooth surface like metal in waterborne industrial paint, IOTA 245 can effectively penetrate and cover the surface. This not only improves the initial adhesion of the coating but also helps in preventing issues such as peeling and flaking over time.

Defect Prevention

IOTA 245 is highly effective in reducing surface friction. This reduction in friction helps to prevent the formation of common coating defects such as shrinkage and orange peel. Shrinkage occurs when the coating retracts from certain areas of the substrate, leaving uneven patches. Orange peel, on the other hand, gives the coating surface an uneven, textured appearance similar to the skin of an orange. By reducing surface tension and friction, IOTA 245 promotes a more uniform flow of the coating, resulting in a smooth and defect - free finish.

High - Temperature Resistance and Compatibility

The wetting agent's high - temperature resistance makes it suitable for applications where the coated material may be exposed to elevated temperatures. For example, in some industrial settings, parts may be subjected to heat during the manufacturing process or in their end - use environment. IOTA 245 can maintain its properties under such conditions, ensuring that the coating remains intact and functional. Additionally, its good compatibility with other substances means that it can be easily incorporated into complex paint and ink formulations. It can be used in combination with various resins, pigments, and other additives without causing adverse reactions. This is especially useful in applications like coating nitrile gloves, where a combination of substances is used to achieve the desired properties of the glove coating.

Hole - Shrinking Ability

In both water and solvent systems, IOTA 245 exhibits a strong ability to shrink holes. This is particularly beneficial in water - borne polyurethane coatings. Holes or pinholes in a coating can be a major problem as they can compromise the integrity of the coating, allowing moisture and other contaminants to penetrate. IOTA 245's ability to close these holes improves the barrier properties of the coating, making it more durable and resistant to environmental factors.

Compatibility with Other Additives and Recoat Ability

IOTA 245 has excellent solubility with other additives commonly used in the coating and ink industry. This means that it can be easily combined with dispersants, thickeners, and other wetting agents to achieve a synergistic effect. Moreover, it does not have a negative impact on the recoat ability of the paint or ink. Recoating is often necessary to enhance the appearance or protective properties of the coating. IOTA 245 ensures that subsequent coats can adhere well to the previous one, without any issues such as poor adhesion or delamination.
