1. Unique chemical structure
IOTA 1291 water-soluble silicone oil, whose core structure is polyether-modified polydimethylsiloxane, is a polymer that cleverly combines hydrophilic organic matter with hydrophobic polysiloxane. This unique molecular structure design combines the excellent properties of polydimethylsiloxane, such as low surface tension, good flexibility and chemical stability, with the hydrophilicity of the polyether segment. The introduction of the polyether segment makes the originally hydrophobic polydimethylsiloxane compatible with water, and also gives it some special properties, such as antistatic properties, better emulsification and dispersibility.
2. Excellent performance characteristics
Low surface tension
IOTA 1291 has extremely low surface tension, which enables it to spread quickly in various systems and effectively reduce interfacial free energy. For example, in water-based coatings, low surface tension enables the coating to better wet the surface of the substrate, improve the adhesion and leveling of the coating, avoid surface defects such as shrinkage holes and fish eyes, thereby making the coating surface smoother and smoother, and improving the appearance quality of the product.
Good hydrophilicity
Thanks to the presence of polyether segments, IOTA 1291 has good hydrophilicity and can be miscible with water in any proportion. This hydrophilicity not only enables it to be stably dispersed in water-based systems, but also interacts with water molecules in some application scenarios to exert special effects. For example, in cosmetics, it can help other hydrophilic ingredients to dissolve and disperse better, enhancing the stability and uniformity of the product.
Antistatic, soft and smooth
This product can give the treated material antistatic properties and reduce problems such as dust adsorption caused by static electricity. At the same time, the molecular film formed on the surface of materials such as fabrics and leather can effectively reduce the friction coefficient of the fiber or leather surface, making the material soft and smooth. In fabric finishing, the fabric treated with IOTA 1291 feels comfortable, as if it has been finely polished, and has good drape.
Breathability
The protective film formed by IOTA 1291 on the surface of the material is not completely closed, but has a certain degree of breathability. This feature is particularly important in cosmetics and fabric applications. In cosmetics, it allows the skin to breathe normally, avoiding problems such as stuffiness and clogged pores caused by the use of cosmetics; in fabric finishing, it can keep the fabrics breathable, so that even after finishing, the wearer can still feel comfortable and not stuffy.
