What is the right application for Carnauba Wax Aerosol Spray?

CAPLINQ has been field­ing ques­tions about what exact­ly the right time is to use car­nau­ba wax aerosol spray. To get bet­ter insight into this ques­tion, it may be best to start with the oppo­site ques­tion, and work our way back.

MJ Gordon Carnauba Wax

Even before we address this, let me start by say­ing that car­nau­ba wax, in its sol­id form is used by most epoxy mold com­pound for­mu­la­tors as one of the wax­es used to pre­vent mold stick­ing in the first place, and that car­nau­ba wax itself is then obvi­ous­ly com­pat­i­ble with epoxy mold com­pounds them­selves. Now let’s get back to the question.

In an ide­al pro­duc­tion envi­ron­ment, the prod­uct mix would be low, the vol­ume would be high, and there would be no mold-chase changes, stuck plungers, clean­ing or main­te­nance repair. There would be a sin­gle epoxy-mold com­pound used with the per­fect bal­ance of adhe­sion pro­mot­ers to stick to the sub­strate (lead­frame or lam­i­nate) with the right lev­el of wax­es to per­fect­ly release from the mold and not cause any plunger stick­ing. In a case like this, not only would car­nau­ba wax aerosol spray be unnec­es­sary, mold release prod­ucts across the board would no longer be needed.

In a flex­i­ble, high-mix pro­duc­tion envi­ron­ment, sprays will always have a place

Tak­ing it a step toward real­i­ty, we’ll throw in that reg­u­lar clean­ing and main­te­nance are a giv­en and every now and then a plunger may get stuck. Still, the prod­uct mix is low and vol­ume is high. In cas­es like this, the ide­al solu­tion would use a trans­fer mold­able mold con­di­tion­er after clean­ing which is less oper­a­tor depen­dent than an aerosol spray. Still, in this case, the car­nau­ba wax aerosol spray would be used to clean the plunger should it stick.

Look­ing at an even more real­is­tic sit­u­a­tion, the pro­duc­tion envi­ron­ment has a high­er mix-vol­ume, mul­ti­ple prod­ucts are made in the same mold and mul­ti­ple mold com­pounds are used in the man­u­fac­ture of the semi­con­duc­tor devices. Fur­ther­more, mold com­pound tri­als to eval­u­ate new prod­ucts and new designs are test­ed. In this case, car­nau­ba wax aerosol spray has mul­ti­ple uses. As before, the prod­uct is used to clean stuck plungers, but it should also be used pri­or to test­ing of any new prod­ucts and after each time the mold is cleaned. It is also used to break in new mold tools and return oth­er ones to ser­vice after maintenance.

In sum­ma­ry, most pro­duc­tion envi­ron­ments would pre­fer not to use a spray, but the real­i­ty is that every pro­duc­tion floor DOES use a spray. The sprays used are typ­i­cal­ly sil­i­cone or PTFE (Teflon) based prod­ucts that are NOT com­pat­i­ble with epoxy mold­ing prod­ucts. These prod­ucts then DO con­t­a­m­i­nate the mold, may cause prod­uct delam­i­na­tion and often are very oper­a­tor sen­si­tive — which is a major rea­son why man­u­fac­tur­ers do look to go to a mold-con­di­tion­er type prod­ucts instead of aerosol sprays.

In these cas­es, car­nau­ba wax aerosol spray is a much supe­ri­or (albeit more expen­sive) prod­uct for the fol­low­ing reasons:

  • Unlike sil­i­cone and PTFE (Teflon) sprays, Car­nau­ba wax aerosol spray is com­pat­i­ble with epox­ies and engi­neer­ing plas­tics and can also be used for a wide-vari­ety of epoxy types instead of care­ful­ly select­ed mold-conditioner
  • Car­nau­ba wax aerosol sprays are flex­i­ble because of the com­pat­i­bil­i­ty with a wide range of epoxy mold­ing compounds
  • The “Green” #909C Car­nau­ba Wax Aerosol Spray uses a “non-flam­ma­ble” sol­vent mak­ing it safe but rapid-drying

In short, high-vol­ume, sin­gle-prod­uct mold­ing lines may ben­e­fit from mov­ing to a less oper­a­tor-depen­dent aerosol spray appli­ca­tion; but in a flex­i­ble, high-mix pro­duc­tion envi­ron­ment, sprays will always have a place, and car­nau­ba wax aerosol sprays are by far the pre­ferred choice in terms of com­pat­i­bil­i­ty and per­for­mance for both epox­ies and oth­er engi­neer­ing plastics.

  1. I have just recent­ly pur­chased a prod­uct of clean­ing wax. It is basi­cal­ly a water­less wax. I have nev­er come across a prod­uct that is so, so good. So good does not real­ly describe this mag­nif­i­cent prod­uct. I pur­chased 2 cans at the time and I have almost gone through all of it. It con­tains CARNAUBA. Tru­ly a mag­nif­i­cent product.

  2. We are devel­op­ing a extrusion/molding process for an oral care prod­uct, por­tions of which will ulti­mate­ly be ingest­ed by the user.

    I found your descrip­tion of your mold release agents inter­est­ing. Espe­cial­ly the Water Sus­pen­sion ver­sion (Blue Label pack­age) as it implies a water emul­sion of the Car­nau­ba Wax. Is the emul­si­fi­er sys­tem in the Blue Label suit­able for use in a process where it will be in con­tact with an oral­ly ingest­ed product?

    I sup­pose that is a nice way of ask­ing what else is in the prod­uct besides Car­nau­ba Wax that we would need to be con­cerned about from a reg­u­la­to­ry sta­tus sit­u­a­tion where we would have to dis­close all chem­i­cals that might be found in trace quan­ti­ties upon analysis?

  3. Dear Dr. Ira Hill,

    It is a nice way of ask­ing indeed, and in return I will offer a nice answer! 

    There are only three ingre­di­ents in the MJ Gor­don Car­nau­ba Wax:
    1 — Water (Approx. 69% by weight)
    2 — Dimethyl Ether (Approx. 30% by weight)
    3 — Car­nau­ba Wax (Approx. 1% by weight)

    The Dimethyl Ether is used as the pro­pel­lant (non CFC of course). As far as dis­clos­ing chem­i­cals for reg­u­la­to­ry pur­pos­es, of course we must also com­ply. The com­plete Mate­r­i­al Safe­ty Data Sheet (MSDS) for Gor­don’s Per­masil #808 Car­nau­ba Wax Mold Release
    (Blue Label) can be found on MJ Gor­don’s Web­site.

  4. Dear sir very use­ful infor­ma­tions about car­nau­ba wax as a mold releas­ing agent, i want to use car­nau­ba wax in aerosol as a fur­ni­ture pol­ish please guide me for this appli­ca­tion. Thank you.

  5. Muham­mad,

    Car­nau­ba Wax has many appli­ca­tions and as you have under­stood, CAPLINQ are experts in the use of Car­nau­ba Wax Aerosol Sprays as mold release agents for semi­con­duc­tors and oth­er crit­i­cal applications.

    Though Car­nau­ba Wax is used in fur­ni­ture pol­ish, it is often one of the raw mate­ri­als used in com­bi­na­tions with bee wax (as described here) due to its high­er melt­ing point, and not as the sole ingredient.

    We do not pro­fess to know if Car­nau­ba Wax alone is suit­able as a fur­ni­ture pol­ish, but if you have pre­vi­ous­ly suc­cess­ful­ly used a sol­id ver­sion of car­nau­ba wax for this pur­pose, then an aerosol ver­sion is avail­able in one of our MJ Gor­don’s Car­nau­ba Wax Aerosol Sprays.

  6. Do you think we can use car­nau­ba wax in aerosol to seal cop­per jew­el­ry? We are des­per­ate try­ing to find a way to make anti tar­nish cop­per jew­el­ry. Thank you very much

  7. This is a ques­tion we can’t answer. If car­nau­ba wax is what you need to make an anti-tar­nish prod­uct, then yes. Unfor­tu­nate­ly, we don’t have much exper­tise in the area of jew­el­ry mak­ing, so we can­not advise whether car­nau­ba wax (aerosol or oth­er­wise) is suit­able to your process.

  8. Dear Sir /Madam,
    Could you tell me whether the Gor­dons Car­nau­ba Wax Aerosols com­ply with the Euro­pean Aerosol Dis­pensers Direc­tive 75/324/EEC, there is no infor­ma­tion on the cans like the reversed epsilon to say they do.

  9. I’m sor­ry, I am not 100% sure whether the MJ Gor­don Car­nau­ba Wax #909C Green does or not. We do sup­ply it exten­sive­ly through Europe and use PostNL (for­mer­ly TNT Post) for deliv­ery with­out any issues.

  10. Hel­lo Sir/Madam,

    Could you tell me if Gor­don car­nau­va wax has an effect on plas­tics or met­als when using on the tem­per­a­ture ranges 180–190 degress cel­cius? Because recent­ly 1 of the prod­ucts in the com­pa­ny that I was work­ing encoun­tered dis­col­oration on the base­plate of the­p­rod­ucts. I am won­der­ing if car­nau­va wax has an effect on the prob­lem that encoun­tered recent­ly or if exces­sive appli­ca­tion of car­nau­va wax has an effect while the prod­ucts was soaked at the M‑pyrol solution.

  11. It is very unlike­ly that the car­nau­ba wax caused any dis­col­oration. It is used often on all sorts of plas­tics and met­als, and there is no inter­ac­tion between the two that would cause dis­col­oration. What is more like­ly is that the SOLVENTS with­in the car­nau­ba wax spray could have caused this. Car­nau­ba wax itself is non-aggre­sive, but it is a sol­id. In order to make this prod­uct liq­uid to be able to apply it, it needs to either be heat­ed up, or emul­si­fied, which is a process that adds sol­vents to make the car­nau­ba wax liq­uid at room tem­per­a­ture. The prod­ucts we sell con­tain a non-flam­ma­ble sol­vent to emul­si­fy the car­nau­ba wax which has a sim­i­lar neu­tral effect on plas­tics and metals.

  12. Hi,

    We have encoun­tered vis­i­ble con­t­a­m­i­na­tion on the base­plate after soak­ing to heat­ed M‑pyrol and the only mate­r­i­al added dur­ing mold­ing the is the car­nau­ba wax(aerosol). Can M‑pyrol wash-off car­nau­ba wax? I have read that M‑pyrol is a poly­mer­iza­tion medi­um for poly­ester, would this mean that instead to be removed car­nau­ba wax tend to make a poly­mer/chain/cross-link that adhere on the baseplate?

  13. It is not impos­si­ble that the car­nau­ba wax is absorbed into the matrix of the prod­uct upon cure. Typ­i­cal­ly, car­nau­ba wax is used in a num­ber of ther­moset mate­ri­als to pro­vide a “self-release” mech­a­nism to release the ther­mo­plas­tic after cure. How­ev­er, the lev­els of car­nau­ba wax used with­in these mate­ri­als is nor­mal­ly quite low, much less than 1%. In aerosol form, the car­nau­ba wax is present local­ly at a much high­er lev­el, so it is unlike­ly that it is all absorbed into the M‑pyrol matrix. This said how­ev­er, we do not have expe­ri­ence with M‑pyrol, so we can com­ment on this spe­cif­ic sub­stance specif­i­cal­ly. Hope this helps you fix your issue.

    Hi! does your prod­uct is real­ly safe? because I saw in the label that your prod­uct is con­tain­ing a chem­i­cal which is known to the State of Cal­i­for­nia that is caus­ing birth defect and oth­er repro­duc­tive harm to human.
