Silicon-based coupling agent F-5
Products introduction
F-5, is a coupling agent for the transparency of our company for the transparent polymer materials and rubber powder modified products of the new coupling agent, the product at room temperature under the micro
transparent white solid, thermally dissolved after as a transparent liquid. In addition to the product characteristics with a more self coupling agent can enhance the transparency of products and products of the effectiveness of the surface brightness is a unique, nontoxic, harmless to environment-friendly agents.

Application
l Ultrafine sodium sulfate, wollastonite, white carbon black, talc powder and various silicate, magnesium hydroxide, aluminum hydroxide, clay, light (weight), such as calcium carbonate.
l Brightener and quality can be directly used for a variety of rubber and lubricant products.
Usage
l Mixer in the interval: first measurement of the powder heated to remove water, and then measurement of the goods, or divided into small crumb into the silo mixer, the material temperature of 110-130 expected, had screen, the rapid cooling can be reference to the activation time for 5-8 minutes.
l Continuous activation device may be the goods in the stainless steel container heated to 70-100 dissolved into a liquid, and then by the use of flow measurement.
Dosage
l Powder dosage of 0.5 ~ 2%, generally 1%.
l Large specific surface area of powders can be used, otherwise less.
l Depending on the application of powder-activated targeted.
1. Products require high mechanical strength can be more appropriate.
2. Products requiring high surface brightness may be more appropriate.
3. Transparency of the powder products can be demanding more appropriate.
4. The best use of the experimental results, as its discretion.
