New choice for single-end reactive silicone oil! IOTA-2170 enhances resin modification


1. Product structure features: The single-end alcohol hydroxyl design has significant advantages
Anhui Aiyouta dual-alcohol hydroxyl single-end capped silicone oil IOTA-2170 has a double-alcohol hydroxyl active group at one end of the molecule and an inert silicon oxide chain segment at the other end. The unique single-end capping structure can avoid excessive cross-linking problems. While introducing the low surface energy, temperature resistance, and flexibility characteristics of silicone, it retains the original mechanical properties of the organic matrix, making it suitable for various resin system modification needs.


2. Main application scenarios, expanding the boundary of material modification
This product can be used for modification of polyurethane, polyester and other resin systems, improving the smoothness of the paint film, weather resistance and scratch resistance. It can also be used in coatings, elastomers and other fields. The reactive hydroxyl groups can undergo chemical bonding with the base resin and will not cause the migration or precipitation of additives. The modification effect can be long-lasting and stable.


3. Customer frequently asked questions, clarifying product usage points
Q: What is the biggest difference between IOTA-2170 and ordinary double-end hydroxyl silicone oil in usage?
A: Ordinary double-end hydroxyl silicone oil can react at both ends, easily forming large-scale cross-linking, causing a significant increase in the viscosity of the system; IOTA-2170 has a single-end capping structure, with only one end having an active group, allowing for controllable grafting modification, and is less prone to gelation. The tolerance of the formulation adjustment is higher.

Q: What are the storage conditions for the product?
A: Store it sealed in a cool and dry environment, away from water vapor and high temperatures. Avoid mixing with strong acidic or strong alkaline materials. Under normal storage conditions, the shelf life is stable.


4. Formula adjustment tips, facilitating production implementation
During the formula addition stage, it is recommended to conduct a small-scale trial to determine the optimal addition ratio. Prioritize pre-mixing evenly with the polyol components before participating in the reaction. The testing of small-batch samples is a key step before mass production, which can verify compatibility, film formation effect and other indicators in advance, reducing production risks.
