WPL-hydroxypropyl silicone oil

[Performance characteristics]

This product is divided into WPL-800 hydroxypropyl silicone oil (molecular weight around 800), WPL-1500 hydroxypropyl silicone oil (molecular weight around 1500), WPL-2500 hydroxypropyl silicone oil (molecular weight 2500) according to the molecular weight.

The common attributes and characteristics of the above three specifications are described as follows: this type of product has a long-chain polydimethylsiloxane segment, and has hydroxypropyl active molecular segments at both ends. It is an excellent polyurethane, poly A block modifier for ester materials, the new polyurethane polyester material after block modification, in addition to the properties of polyurethane and polyester, it also combines the softness, lubricity, and high resistance of polydimethylsiloxane Excellent properties such as high and low temperature properties are brought to new materials, forming a new style and new property materials.

Three kinds of hydroxypropyl silicone oils with different molecular weights, the larger the molecular weight, the more siloxane chains are brought into the modified new material, and the more prominent the flexibility and smoothness of the siloxane. The molecular weight specification to choose depends on the size of your own product structure grid and the compatibility with the system.

This product has limited compatibility with aromatic hydrocarbons and can be diluted with esters, ketones and alcohols.

Structural formula: HO(CH2)3SiO[(CH3)2SiO]mSi(CH2)3OH

[use]

Mainly used in silicone rubber, polyurethane, coating, etc.

1. Used for polyurethane or polyester modification, it has excellent anti-sticking and peeling properties, and improves the softness, smoothness and temperature resistance of synthetic leather.

2. Used in solvent-based coatings, it has good anti-graffiti, anti-fogging, and anti-floating effects, and can obtain a smooth and full hand feeling. The prepared coating has better UV resistance, anti-yellowing performance, and low temperature resistance. Anti-brittle hard properties.

3. As a reactive modifier of organic resins, it improves the fluidity and leveling of resin coatings.

4. When producing paint and modifying other resins, adding this product can improve the compatibility of various components and improve the fluidity.

5. Other applications to be developed.

[Usage and Dosage]

1. Add a small amount (3% to 30%, depending on the required performance) for polyurethane modification to replace the polyol in the original formula.

2. As a release agent and release agent with excellent performance. The recommended amount is usually 3-20%.

[packaging and storage]

Packing: 25kg, 50kg, 200kg plastic drum

Storage: Sealed storage, the storage period at room temperature is 12 months, and contact with tin (such as metal containers) will shorten the storage stability.
