Application of silicone resinSilicone resin is excellent in thermaloxidation stability, cold resistance, weather resistance, electricalinsulation, water repellency and releasability release the like. Accordingly,the silicone is widely used as insulation resistance, high temperature paint.Such as H-class electrical appliances used to impregnate the coil has beenreached with the insulation, impregnated peel ply, fiberglass and asbestoscloth, made of electrical insulation casing and electrical insu ...

Characterization of amino silicone oilUsually 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 ...

Selection and use of silicone defoamersshould pay attention to the problemAnd 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 ...

UV-curable silicone releasing agentUV-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 ...

Formulation suitable for mechanical bondingwith the label release paper silicone release agentMechanical 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 ...

Improving the storage stability of therelease filmPolyorganosiloxane 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,leading to peeling deteriorates. Especially acrylics adhesives, small initialpeel force after placing larger. Phenolic antioxidant added to allylgroup-containing polyorganosiloxane, it is po ...

Addition-curing silicone emulsion releasingagentCompared 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 packa ...

Solvent type addition cure siliconereleasing agentSolids 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 ...

Addition silicone releasing agent has thefollowing five characteristics1. 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 solutio ...

Silicone release agent species and productformSilicone anti-blocking agent bycross-linking mechanism can be divided into condensation type, addition typeand radiation type. From the comparison of the degree of curing, working time,release properties, blocking resistance and coating formulations and otheraspects of design freedom, plus molded advantage more condensed than iscurrently the main varieties of organic silicon release agent. Ultravioletlight and electron beam radiation curing many theo ...
