For a long time, the production of building and industrial coatings has been plagued by surface defects such as orange peel, pinholes, and brush marks. Polyether-modified leveling silicone oil has become a standard additive in the formulation, achieving an upgrade in surface flatness by regulating surface tension. During the coating mixing and spraying process, the surface tension of water-based coatings and UV light oil is uneven, and oil stains on the substrate are prone to cause pinhole defects. A small amount of leveling silicone oil can reduce the surface tension of the system, allowing the coating to flow freely and fill fine lines, completely eliminating brush marks and orange peel patterns left by manual painting, and significantly improving the bright gloss of the paint film.
This type of silicone oil molecule has long-wave leveling properties and does not damage the adhesion between multiple coating layers. It can be used for wood coatings, plastic coatings, and industrial baking coatings. The addition amount is only 0.1% - 0.8%, which can achieve the desired effect and will not cause problems such as loss of gloss and oil stains caused by ordinary additives. After the coating is cured, the silicone oil slowly migrates to the surface, forming a thin and smooth silicone film, improving the scratch and stain resistance of the paint surface, and making dust and water stains difficult to adhere.
The domestic IOTA series of leveling silicone oil is compatible with all water-based environmentally friendly systems, with low VOC and no odor, meeting the environmental control standards for home decoration coatings and outdoor industrial coatings. Many wood coating manufacturers have reported that after introducing the dedicated leveling silicone oil, the rework rate of the paint surface has decreased by 70%, and the premium space of high-end furniture paint products has significantly increased. With the complete replacement of solvent-based products by water-based coatings in China, the market demand for leveling modified silicone oil continues to grow steadily, becoming a core essential category of coating additives.
