——Replacement of same productsfrom Sweden Perstorp, Japan Daiso—

TMPDE is acompound of three kinds of Allyl Ether, full name is TrimethylolpropaneDiallyl Ether, including Monoallyl Ether, Diallyl Ether, Triallyl Ether.Because of such structure, TMPDE becomes a excellent Air Drying Agent, iswidely used in Unsaturated Polyester Resin, Alkyd Resin, Polyurethane Resin,Epoxy Resin, Soluble Resin, Poly-Putty Base Resin, etc.

Basic ChemicalStructure

TMPDE product isa compound of Trimethylolpropane Monoallyl Ether, Diallyl Ether, Triallyl Etherwith different proportion.

Chemical Performance                                                                

TMPDE products perform very stably underusual temperature and humidity, possessing typical character of ether andalcohol functional group. Ether functional group can offer air dryingcharacter, alcohol functional group can be taken esterify reaction, so TMPDE iswidely applied in synthetic resin.

Along with the continuous advancement ofsociety, market has higher requirement as to special resin character by higherhardness, clearance color, better corrosion resistance environmental character,and quicker speed of drying in the air, and TMPDE can offer such performancewith special molecule structure, better physics character, which win preferenceof professional personage.

TMPDEApplication

TMPDE dosagerise continuously in specialty resin, application includes Unsaturatedpolyester resin, Alkyd, Polyurethane resin, Epoxy resin, Water based resin.

A  Unsaturatedpolyester resin

Traditionalunsaturated polyester resin is mainly synthetic by saturated dibasic acid,unsaturated dibasic acid, polyhydric alcohol and styrene . Such unsaturatedpolyester curing processing is anaerobic, namely keep lasting sticky of surfacetouched by air because of oxygenic polyanion reaction, therefore, when used inmaking coating, widely adopt plastic film covering or add paraffin wax to isolateair, and astrict the wide application in coating.   CurrentlyAir Drying Unsaturated Polyester has been widely applied in coating, andappraised by customer. Air Drying Unsaturated Polyester is mainly leading ‘ AirDrying Sense regimental’ in synthetic resin, like Allyl ether（CH2=CHCH2-O-）, utilizing those sense regimental toabsorb oxygen in air, occur forming curing film action  by dry oil inair, capture oxygen in coating film priority, restrain inhibition reaction offree radical cross linking with oxygen to unsaturated polyester resin, realizespainting film self-drying, whereas TMPDE can offer Allyl ether senseregimental, so adding TMPDE in Synthetic unsaturated polyester resin candevelop polyester air drying character, thereby realizes painting filmself-drying character, develop unsaturated polyester level. Recommendedreference material as follows.

First Step

Second Step

SyntheticProcessing

1.         Protectedby Nitrogen, Plunge first step material into,

2.         Warmup to 155℃ and keep 1 hour,

3.         Warmup by speed 0.2℃/min until to 200℃,

4.         Esterifyuntil acid number reach 70-80mg KOH/g,

5.         Coolinguntil under160℃ then adding second step material,

6.         Warmup to 185℃ or so,esterifying to qualified acid number,

7.         Vacuumdistillation, make polyester reach qualified viscidity, cooling down, Dilution,discharging,

Adding TMPDE inUnsaturated polyester can not only improve air drying character, but also canprovide following

advantage,

a)         Polishingwithout wax,

b)        Improvescuff resistance and corrosion resistance,

c)         Improveheat resistance, solvent resistance, and chemical physics resistance,

d)        Nobecome yellow during drying and aging procedure,

e)         Candry quickly, and only little styrene vaporizes, reduce VOC content.

B  AlkydResin

Adding TMPDE insynthetic alkyd resin procedure can improve some Alkyd character, thereby pushsynthetic alkyd resin to a higher level.

1.         Improvedrying character,

2.         ClearResin Color,

3.         Improvewater resistance,

4.         Havehigher solid content in the same viscidity,

Recommend to add10% TMPDE weight in Synthetic resin formulation.

C  PolyurethaneResin

During Syntheticprocessing of Polyurethane resin, TMPDE can be used in double compositionIsocyanate system, and used in Acylate of Hydroxyl group ----Isocyanate,improving drying character by Allyl Ether functional group.

D  EpoxyResin

TMPDE can beapplied in Epoxy surface coating film binding agent, can receive tough coatingwhich is suitable for inner and outer floor surface.

TMPDE Storage

It need muchcaution towards TMPDE storage, when TMPDE touch with air or exposure under thesunshine, can easily form peroxide.Recommended highest temperature is 25℃，if tank is open,please seal up immediately and clear offensive. odor by inactivegas. If storage time lasts too long, suggest control the peroxide contentbefore using, best way is distillingagain. Over amount of Peroxide content may arouse side reaction, make resincolor deeper, and make viscidity Unsaturatedpolyester arises up too quickly.

TMPDE Touch

The same ascommon chemical material，take suitableventilated equipment and wear protectable appliance to avoid touch with skindirectly when using TMPDE, and TMPDE can arouse irritation of eye system andbreath system, therefore, suggest wear work clothes and protectable when usingit.
