Moldova Differences in water-based mineral oil Free of silicone defoamers(3)





The larger the molecular weight, the stronger the control ability of its surface state, and the better its skid resistance and adhesion resistance, such as the 1070 and 1071 series products of the friction chemical industry.
There are two methods for bonding modified polyester or polyether to siloxanes: one is a silicon oxygen bond; The other is silicon carbon chains, which generally have less thermal stability and water resistance than the latter.
The compatibility of polyether and polyester modified siloxanes with resins has been greatly improved, reducing surface tension, controlling surface flow, increasing slip resistance, anti shrinkage, and anti adhesion. Some products also have interlayer adhesion issues. In particular, polyether modified polysiloxanes have poor thermal stability and are prone to foam stabilization. It is important to pay attention to the negative effects of these products when applying them.

替换城市  Waterborne mineral oil Free of silicone defoamers are suitable for use in water-based systems with weak emulsifying properties, such as latex paints, coatings, adhesives, inks, and other systems with low emulsifying properties. They are easy to emulsify and form uniform distribution in water-based systems, thereby reducing the likelihood of surface defects such as shrinkage and loss of gloss, and also reducing microbubbles. However, it should be noted that mineral oils and waxes, which contain a small amount of organosilicon, and adopt special preparation processes, have excellent product storage stability, and are not prone to separation or sedimentation even after long-term storage.
