Defoamers need role -- 2016-09-23

Current theories about the formation ofanti-foaming and foam degassing is different. Defoamers the role of the air trapped in the interface. Defoaming agent role in the process andthe coated film after coating is completed, so that the coating film dispersedin the tiny air (microbubbles), rapid rise to the surface. But the practical application is oftennot clearly make this distinction. Defoamers also can eliminate microbubbles tosome extent. Defoamersdefoaming mechanism discussed below in water ...

Foam definitions and concepts -- 2016-09-22

It can be defined as the foam of air bubbles in aliquid medium in a stable dispersion. If the general air into the liquid, thebubble generated can assume a spherical shape. Since the air is lessdense than the liquid, and thus it will migrate to the surface, when the gasreaches the surface of the liquid without surfactant, the bubble will burst, theair inside the bubble dissipates, the liquid surrounding the bubble in theprevious and together. Thus, the pure liquid (liquid containing nosurfactant ...

Definition of Some Surfactants -- 2016-09-21

In many inks and coatings processingproduction process, the need to use surface-active substances to achievespecial effects. Forexample, in the production of water-based paint, water-insoluble base materialproduction, water-insoluble base material is required to deal with the use ofemulsifiers. At the same time,we have to improve substrate wetting and coating pigment dispersion by usingadditives.Surfactant most importantcharacteristic is that they have a tendency to build in the interface, such ...

Low surface energy silicone marine antifouling coatings -- 2016-09-20

Organic silicon antifouling paint has asmooth surface, marine life is difficult in the above attachment, even if notfirmly attached, in water or other external force is very easy to fall off. Studieshave shown that the surface coating can be less than a 12 X10 N / m, in orderto effectively prevent the attachment of marine organisms.

Elastoplastic silicone "three" paint -- 2016-09-19

In the present, all "three"paint, elastoplastic silicone "three" best overall performancecoatings, having a room temperature or low temperature curing, construction andconvenient features. After curing adhesive coating both flexibility, but alsothe smooth transparent surface, and resistant to high and low impact,high-frequency dielectric properties, excellent "three" performance,etc., can meet the whole high and low frequencies and protective coating hybridcircuit. ...

Silicone insulating powder coating -- 2016-09-18

Silicone insulation coatings availablesilicone resin or a silicone-modified epoxy resin, silicone-modified polyesterfilm material, mainly varnishes and enamels classes, both high temperaturecuring type, there are also low-temperature curing type. In a wide frequencyrange, the dielectric constant and dielectric loss is very small, and smallchanges with temperature. At present, most silicone-modified epoxy resins areliquid, powder coating is difficult to meet the requirements. Use of modifiedepoxy ...

Silicone elastomers decorative coatings -- 2016-09-14

Flexible silicone latex decorative coatingsis to introduce a silicone bond in the acrylic resin polymerized into the newfilm material. Add silicone improved weathering resistance and durability of anacrylic resin, coating an elongation of 700% to 300%, fine cracks mask wall,the coating layers to improve the decorative features. General multi-stepemulsion polymerization into a composite polymer latex, the center of a hardresin. Compared with ordinary glue residue, coating flexibility and betterwa ...

"Breathe" silicone waterproof coating -- 2016-09-13

Wall material absorbs moisture will causeserious damage to the wall itself, needs the moisture in the wall of a flowchannel in the form of water vapor evaporation from the wall material. Therefore,reducing the water absorption of building materials, exterior wall materialsgiven "breathing" function, is to improve the building decoration,waterproof important way. Silicone Coating with organopolysiloxane with certainreactive groups as the main film-forming material, its backbone structur ...

Further cross-linked silicone coatings produced above 400 degrees -- 2016-09-12

Insulation coatingsAnother outstanding performance siliconeresin is its excellent electrical insulating properties, insulation performancelevel is 180 ℃, belong to H-class insulation. Its dielectric constant anddielectric loss, insulation resistance of between 0 ~ 250 ℃ littlechange, is a good high-temperature electrical insulation coatings, long-termuse at 200 ℃. And having a coating resistant to moisture, acid and alkaliresistance, radiation resistance, ozone resistance, corona, flame retar ...

Superior performance -- 2016-09-09

In the coating system, the silicone resinin between organic and inorganic fillers, and mineral substrates and coatingsystems containing silicon bonding played a good role. Like fried rice cakemixed resin reinforced soil like those who play enhancement. Because of thisstrong bonding effect, it may be formulated above the critical pigment volumeconcentration (CPVC) containing very high filler Organisation coatings with. Thesecoatings are inherently porous and water vapor through sex - as it protec ...
