Hits: 274 img

1、Anti-foaming agent field:

Improve the high temperature resistance, strong alkali resistance and foam inhibition performance of defoamer

1.1. MQ can be used to prepare silicone defoamer with high temperature and strong alkali resistance.

Application in high temperature and strong alkali defoamer: mainly through the addition of medium and high viscosity hydroxyl silicone oil and MQ silicone resin to synthesize a high degree of branched polymer, in order to improve the defoamer's resistance to high temperature and strong alkali performance, the dosage is between 5-10%.

1.2 Preparation of antifoam agent by compounding MQ silicone resin and polyether modified silicone oil.

The smaller the MQ ratio, the more complex its spatial network structure, the more conducive to improving the antifoaming agent foam inhibition performance, but too small is difficult to dissolve in methyl silicone oil.

2、Field of mold releasing agent:

Improve the demolding durability of the release agent, and the demolding effect is more ideal for high adhesive resins (such as polyurethane, epoxy resin, etc.);

3、Waterproofing agent field:

The structure of polysiloxane determines that silicone resin has hydrophobicity, and its contact angle with water is greater than 90 ° and is used in waterproof materials.

4、Silicone rubber reinforcing filler:

With MQ silicone resin as reinforcing agent, liquid silicone rubber products have a certain mechanical strength and high transmittance, good fluidity of the rubber before vulcanization;

5、Silicone pressure-sensitive adhesive reinforcing and tackifying agent:

Regulate cohesion, adhesion and initial adhesion;

6、Cosmetic field:

For surface protective coating, can eliminate the viscosity of silicone oil, improve the slipperiness, scratch resistance, and improve the gloss;

7, plus molding anti-adhesive peel regulator:

Vinyl MQ silicone resin can be used as the peeling regulator of the anti-adhesive agent for adding molding;

8、Hydrogen-containing MQ silicone resin is mainly used as a crosslinking agent for silicone-hydrogen addition of vulcanized silicone rubber and other raw materials for modified MQ silicone resin;
