Cosmetic -- 2016-08-04

The main function of the surfactant incosmetics include emulsification, dispersion, solubilization, foaming,cleaning, lubrication and soft like. Surfactants have widely used in cosmetics,it plays an important role. Cosmetics utilized in the performance of asurfactant which is not only a single performance, but to use its moreproperties. Therefore, the surface-active agent in the production of cosmeticsis an indispensable raw material, widely used in cosmetics. Cosmetics refers tothe smear, spray ...

Characterization of amino silicone oil -- 2016-08-03

Usually ammonia value, viscosity andreactivity of three parameters to characterize the molecular structure of aminosilicone oil.(1) Amine valueAmino silicone oil to produce soft fibers,smoothing effect, largely related to the number of amino groups in themolecule. Ammonia is a value characterizing the form of amino group content,namely the amino silicone and 1g consumed concentration 1mol • L-1volume of hydrochloric acid. Fabric softening agent used as the N-β- aminoethyl-γ- aminopropyl methy ...

Selection and use of silicone defoamers should pay attention to the problem -- 2016-08-02

And other non-silicone defoamers assilicone defoamers are also subject to restrictions on the use of environmentalconditions. Binding conditions and different defoamer performance liveenvironment to determine the appropriate species. When necessary, it isdesirable foaming liquid sample to simulate the actual conditions of use anddefoaming experiments to determine the amount of anti-foaming agent.In actual use, the bubbling liquid siliconedefoamers added amount of 1 × 10-6 ~ 100 × 10-6 can getv ...

UV-curable silicone releasing agent -- 2016-08-01

UV-curable anti-blocking agent is fasterthan the above heat-curable anti-adhesive curing speed. And in principle, withheating, ideal for low heat resistance of the substrate. As release-treatedpolyethylene, polypropylene, polyvinyl chloride film. UV-curable siliconereleasing agent and by product form can be divided into solvent-free andsolvent-based. The latter is mainly used for coating film thickness of 0.5μm orless. Press the curing reaction by type, mainly in the following four kinds: Merca ...

Formulation suitable for mechanical bonding with the label release paper silicone release agent -- 2016-07-29

Mechanical bonding labels and adhesivetape, peel speed large. Easy to make and release paper tape vibrate, generatingsound, affecting operating environment. And affect the tape, label positioningaccuracy of fit. Allyl-modified polyorganosiloxane and allyl amide groupmodified polysiloxane release films made from the combination may have beenstripped of vibration, does not emit sound peeling. Allyl amide group-modifiedpolyorganosiloxane-containing substituent polydimethyl siloxane substituentgroup ...

Improving the storage stability of the release film -- 2016-07-28

Polyorganosiloxane molecule radicalreactive functional group content is large, it can improve the electron beamcuring type silicone releasing agent curability. However, due to the polarityincreased, also release film hardness and surface tension becomes large, leadingto peeling deteriorates. Especially acrylics adhesives, small initial peelforce after placing larger. Phenolic antioxidant added to allylgroup-containing polyorganosiloxane, it is possible to improve the storagestability of the peel ...

Addition-curing silicone emulsion releasing agent -- 2016-07-26

Compared with solvent-addition siliconerelease agent emulsion having safety and no environmental pollution. However,the narrow temperature range, the curing time, curing conditions typicalvarieties of 120 ~ 150 ℃, 30 ~ 40s. Due to limitations dosage range and peel force byemulsion type addition silicone releasing agent is mainly used fornon-pressure-sensitive adhesive. Such as rubber, asphalt and other stickysubstances packaging, sticky food packaging. Some varieties can also be usedfor wallpap ...

Solvent type addition cure silicone releasing agent -- 2016-07-25

Solids solvent-addition silicone releaseagent is generally 30%. When diluted with toluene, n-hexane, etc. to a solidcontent of 2% to 10%, dubbed a catalyst coating liquid. To minimize the amountof solvent can also be formulated as solids content of the coating liquid 10%to 30%. Concentration or viscosity of the coating liquid to the substratewettability, curing and the use of others have subtle effects. It is generallythe concentration should be specified merchandise conditions to prepare acoati ...

Addition silicone releasing agent has the following five characteristics -- 2016-07-22

1. Low curing temperature and curing isgood, can be used for double-sided coating, does not produce adhesion.2. Formulation design flexibility, you canuse the crosslinking density of the release properties make appropriateadjustments.3. Peeling speed on small peel force.4. It can be used acetylene alcohol,dibasic acids containing double bonds and lipids as platinum catalystinhibitors that extend the use of the coating solution.5. Easily poisoned platinum catalyst losesactivity, should be avoided ...
