MRE-C909 replaces MJGordon Permasil #909C

Long con­sid­ered an indus­try stan­dard, MJ Gor­don Per­masil #909C car­nau­ba wax spray is no longer avail­able and is now replaced by Chem­linq MRE-C909.

If any man­u­fac­tur­er of semi­con­duc­tor devices were ever asked what they used to release epoxy mold com­pound from the mold, their answer was always the same: MJ Gor­don Per­masil #909C. Long con­sid­ered an indus­try stan­dard, M.J. Gor­don’s Car­nau­ba Wax Mold Release is dubbed as the “World’s Finest Car­nau­ba Wax Mold Release”. The rea­son for this pres­ti­gious hon­or was sim­ply because it worked so well.

What is MJ Gordon #909C?

MJ Gor­don Per­masil #909C is a non-flam­ma­ble, car­nau­ba wax aerosol spray used as a mold release agent for epoxy mold­ing com­pounds and oth­er ther­moset plas­tics. Not only did was the car­nau­ba wax com­pat­i­ble with epoxy, in some cas­es, it actu­al­ly enhances the final prop­er­ties, includ­ing ten­sile strength and max­i­mum dis­place­ment. 

What is so spe­cial about M.J Gor­don’s Car­nau­ba Wax Release is not nec­es­sar­i­ly the car­nau­ba wax itself (though this is also an impor­tant con­sid­er­a­tion), but the patent­ed process of mak­ing it avail­able in aerosol spray form. Typ­i­cal­ly, car­nau­ba wax is only avail­able in flakes, pow­der or clumps. These clumps are the same ones typ­i­cal­ly used by semi­con­duc­tor man­u­fac­tur­ers to wax the mold plunger or break in new molds. What the car­nau­ba wax aerosol spray ver­sion allows is uni­for­mi­ty, con­trol, and the con­ve­nience of an aerosol spray.

MJ Gordon Permasil 909C uses non-REACH-registered ingredients

Trou­bles with Per­masil #909C began back in June of 2007 when the Euro­pean Union intro­duced REACH, essen­tial­ly forc­ing man­u­fac­tur­ers to com­ply with new dis­clo­sure and reg­is­tra­tion reg­u­la­tions. As a long-time rep­re­sen­ta­tive of MJ Gor­don, CAPLINQ reached out to Allan B Gor­don of MJ Gor­don to dis­cuss alter­na­tives to the ingre­di­ents to be able to ensure con­tin­u­ous sup­ply after REACH was ful­ly intro­duced in 2018.

At the time, CAPLINQ was informed that there were no planned devel­op­ments or replace­ments for the MJ Gor­don Per­masil #909C.

Sens­ing the dan­ger this rep­re­sent­ed to CAPLIN­Q’s semi­con­duc­tor cus­tomers, we set about to start to devel­op our own alter­na­tive to the Per­masil 909C car­nau­ba wax for­mu­la­tion. After almost 10 years of devel­op­ment, this devel­op­ment result­ed in our Chem­linq MRE-C909 car­nau­ba wax aerosol epoxy mold release.

M.J. Gordon stop supplying Permasil 909C

In ear­ly 2019, CAPLINQ start­ed get­ting many phone calls, emails and inquiries about our abil­i­ty to sup­ply the MJ Gor­don #909C. We tried reach­ing out to Allan Gor­don and com­pa­ny but received no replies to any of the emails, or phone calls. 

Since CAPLINQ was just one of two dis­trib­u­tors for MJ Gor­don in Europe, the oth­er being Kemtron in the UK, we reached out to Kemtron to see if they expe­ri­enced the same thing. They informed us that they also had the same expe­ri­ence, they had also tried tele­phon­ing, email­ing etc but received no reply. They even con­tact­ed the Pitts­field local Police and asked if they could check to see if there had been a fam­i­ly dis­as­ter but received no reply.

In July of 2019, Kemtron ran out of stock and have had to pre­sume that the MJ Gor­don Per­masil 909C was no longer avail­able. Kemtron then con­tact­ed all of their cus­tomers and advised them to con­tact CAPLINQ as we had suc­cess­ful­ly devel­oped an alter­na­tive to 909C.

Below is the let­ter Kemtron had writ­ten to their cus­tomers:

I am writ­ing to advise you that we have not been able to con­tact MJ Gor­don Co for the last 6 weeks. This is very strange, and we can only pre­sume that the com­pa­ny is no longer trad­ing. We have spo­ken to their oth­er dis­trib­u­tors in the Nether­lands (CAPLINQ) and Sin­ga­pore and they report the same and have also had no com­mu­ni­ca­tion from them. Inter­net search­es and com­pa­ny reports have proved neg­a­tive in find­ing infor­ma­tion as to what could have hap­pened. MJ Gor­don was a very small com­pa­ny of just 2–3 peo­ple.

Our stocks of Per­masil 909C are now down to 2 box­es (24 cans) and when these have gone we will not be in a posi­tion to sup­ply this prod­uct any­more.

There is a prod­uct that may be able to replace the Gor­dons 909C which is avail­able from CAPLINQ. Please see https://www.caplinq.com/mre-c909-carnauba-wax-non-silicone-epoxy-mold-release-spray-mre-c909-series.html

I sug­gest you con­tact Caplinq direct­ly, the cus­tomer ser­vice con­tact is Mar­jette Oost­er­veen and she can be reached by email at orders@caplinq.com.

CAPLINQ MRE-C909 is a proven alternative to MJ Gordon 909C

For­tu­nate­ly for CAPLINQ and our cus­tomers, we had been prepar­ing for such a ter­ri­ble turn of events. Since the devel­op­ment of the MRE-C909, we had suc­cess­ful­ly con­vert­ed more than 20 cus­tomers from Per­masil 909C to our Chem­linq MRE-C909. Each cus­tomer spent 2–3 month val­i­dat­ing the prod­uct and each one then con­firmed back to CAPLINQ that this MRE-C909 car­nau­ba wax aerosol spray for epoxy mold­ing com­pound behaved the same as its pre­de­ces­sor. 

Please vis­it our web­site to view our entire range of semi­con­duc­tor mold main­te­nance prod­ucts includ­ing our semi­con­duc­tor epoxy mold release agents and specif­i­cal­ly our Chem­linq MRE-C909. You can also con­tact us about if you have any ques­tions about the MJ Gor­don 909C prod­uct.
