Surfactant IOTA245 enhances the quality of water-based coatings and resolves the problem of paint shrinkage cavities.
Wetting agent IOTA 245-IOTA
1. The surfactant IOTA245 belongs to the polyether-modified silicone oil type additive.
It has a colorless to light yellow liquid appearance and possesses low surface tension. It has excellent wetting and penetration properties on substrates, good water solubility, and can be compatible with both water-based and some solvent-based systems. It is widely applicable to water-based industrial paints, water-based wood coatings, water-based polyurethane, printing pastes, water-based varnish, adhesives, etc., and can also be used in butyl rubber glove coating scenarios. Its high-temperature resistance is suitable for many high-temperature processing techniques. The product can reduce the friction on the coating surface, improve the leveling effect, and reduce common coating defects such as orange peel and shrinkage cavities.
2. Practical application guide to control the reasonable addition range
The recommended addition amount of this product is 0.1%-0.5% of the total formula of coatings and inks. It can be directly mixed and added during the production stage, and has good compatibility with other additives in the system, without the risk of stratification or precipitation. The product should be stored in a cool, dry, and normal temperature environment. It is packaged in a sealed plastic bucket to avoid direct sunlight exposure and low-temperature freezing, ensuring the stability of the additive.
3. Customer frequently asked questions to clarify usage concerns
Q: Will adding IOTA245 affect the re-coating of the coating?
A: When used within the normal addition range, it will not damage the re-coating adhesion. It can be stably used in multi-layer coating schemes. This is one of the advantages of this additive.
Q: Can it only be used in water-based systems, or can solvent-based paints be tested?
A: The water-based system has the best effect and also has certain anti-shrinkage capabilities. For solvent-based systems, a small-scale test can be conducted to confirm compatibility before mass production.
4. Market implementation feedback, steadily improving the product yield rate
Many coating production sites have reported that after introducing IOTA245, the uneven wetting of the substrate caused by missed coating and frosting problems have significantly decreased, and the coating flatness has improved. The addition ratio of this additive is low, and it has a controllable impact on the formula cost. It balances processing stability and product appearance, becoming a common choice for optimizing water-based coatings and inks formulas.
