MEKP availability

[BoomerangInfo]

I was just talking to Armsmodelit and they tell me you can't get MEKP shipped anymore, and I could only get it from a hardware store. I know Bunnings have it, but 20ml is over $5, compared to $7 for 100ml listed at the casting places.

Anyone had difficulties getting it, or know any way I can get a bigger bottle without needing it transported?

The guy suggested I got for Epoxy or Polyurethane resins instead. Problem is they are nearly 3x more expensive than the Polyester.

Thanks. Russell.

Russell get it from Barnes they will road freight it I think they also have larger bottles.

Ok I'll check it out. They haven't got back to me on my other query yet. The Arms guy was suggesting no courier will ship it anymore - some recent change he reckoned, but we'll see.

Russell,
Try FMS (Fibreglass Material Services) they use to have branches throughout Oz, I am sure they will be able to give you any advise you need on shipping. I use to deal with them when I was building boats for a living and always found them very helpful.
If they can't help you then you could try fgi (Fibreglass International) they are one of the biggest suppliers of composite materials in the country. Links to their websites below.

Thanks Brett,

I've emailed FMS, who have 1 static web page - lol, and will contact FGI later, as they have a web site with no email address! They list a sales centre in Brisbane that I could visit when I get down there.

I know MEK as MethalEthalKetone (Sp) and can be used as a thinner / Cleaning Solvent but what is MEKP

[Bob38S]

Not sure if this helps or what you are using it for but you can get Methyl Ethyl Keytone and an Acetone mix in -

"Bostik Plumb-Weld PVC Priming fluid" from any plumbing supply place - it comes in clear for under $5 for 500mL.

It's a catalyst for Polyester casting resin

From Wikipedia


Methyl ethyl ketone peroxide (MEKP) is an organic peroxide (http://en.wikipedia.org/wiki/Organic_peroxide), a high explosive similar to acetone peroxide (http://en.wikipedia.org/wiki/Acetone_peroxide). MEKP is a colorless, oily liquid whereas acetone peroxide is a white powder at STP (http://en.wikipedia.org/wiki/Standard_conditions_for_temperature_and_pressure); MEKP is slightly less sensitive to shock and temperature, and more stable in storage.
Dilute solutions (http://en.wikipedia.org/wiki/Solution) of 30 to 60% MEKP are used in industry and by hobbyists as the catalyst (http://en.wikipedia.org/wiki/Catalyst) which initiates the polymerization (http://en.wikipedia.org/wiki/Polymerization) of polyester (http://en.wikipedia.org/wiki/Polyester) resins (http://en.wikipedia.org/wiki/Resin) used in glass-reinforced plastic (http://en.wikipedia.org/wiki/Glass-reinforced_plastic), and casting. For this application, MEKP is dissolved in dimethyl phthalate (http://en.wikipedia.org/wiki/Dimethyl_phthalate), cyclohexane peroxide (http://en.wikipedia.org/w/index.php?title=Cyclohexane_peroxide&action=edit&redlink=1), or diallyl phthalate (http://en.wikipedia.org/w/index.php?title=Diallyl_phthalate&action=edit&redlink=1) to reduce sensitivity to shock. Benzoyl peroxide (http://en.wikipedia.org/wiki/Benzoyl_peroxide) can be used for the same purpose.
MEKP is a severe skin irritant and can cause progressive corrosive damage or blindness.
MEKP, acetone peroxide and HMTD have all been reported to be the explosives used in the alleged 2006 transatlantic aircraft plot (http://en.wikipedia.org/wiki/2006_transatlantic_aircraft_plot).

Butanone is a manufactured organic chemical (http://en.wikipedia.org/wiki/Organic_chemistry). It is a colorless liquid with a sharp, sweet butterscotch odor reminiscent of acetone (http://en.wikipedia.org/wiki/Acetone). It is a ketone (http://en.wikipedia.org/wiki/Ketone), also known as methyl ethyl ketone (MEK).
Butanone is produced in large quantities. Nearly half of it is used in paints (http://en.wikipedia.org/wiki/Paint) and other coatings because it will quickly evaporate. It dissolves (http://en.wikipedia.org/wiki/Solvation) many substances and is used as a solvent (http://en.wikipedia.org/wiki/Solvent) in processes involving gums (http://en.wikipedia.org/wiki/Natural_gum), resins (http://en.wikipedia.org/wiki/Resin), cellulose acetate (http://en.wikipedia.org/wiki/Cellulose_acetate) and nitrocellulose (http://en.wikipedia.org/wiki/Cellulose_nitrate) coatings and in vinyl films. It is also used in the synthetic (http://en.wikipedia.org/wiki/Chemical_synthesis) rubber (http://en.wikipedia.org/wiki/Rubber) industry, and as a catalyst for polyester resin (http://en.wikipedia.org/wiki/Polyester_resin) hardening. It is also used in manufacturing plastics, textiles, in the production of paraffin wax (http://en.wikipedia.org/wiki/Paraffin_wax), and in household products such as lacquer (http://en.wikipedia.org/wiki/Lacquer), varnishes (http://en.wikipedia.org/wiki/Varnish), paint remover, a denaturing agent for denatured alcohol (http://en.wikipedia.org/wiki/Denatured_alcohol), glues (http://en.wikipedia.org/wiki/Adhesive) and as a cleaning agent. MEK is also used in dry erase markers as the solvent of the erasable dye. It is used for synthesis of methyl ethyl ketone peroxide (http://en.wikipedia.org/wiki/Methyl_ethyl_ketone_peroxide), a catalyst for some polymerization (http://en.wikipedia.org/wiki/Polymerization) reactions. It is highly flammable (http://en.wikipedia.org/wiki/Flammable). It is not considered a large health threat.
Butanone occurs as a natural product. It is made by some trees and found in some fruits (http://en.wikipedia.org/wiki/Fruit) and vegetables (http://en.wikipedia.org/wiki/Vegetable) in small amounts. It is also released to the air from car (http://en.wikipedia.org/wiki/Automobile) and truck (http://en.wikipedia.org/wiki/Truck) exhausts.
So no, MEK and MEKP are not the same, and I doubt being mixed with Acetone is appropriate as a catalyst either, but thanks anyway.

Well, thanks to Brett's suggestion, it appears the place is Brisbane has a product called Escon which may be a suitable resin, and cheaper than Barnes. However they have no pigments. According to that guy, Polyesthers don't take pigments very well even. They do have the MEKP though as well. The other replace hasn't responded to me.

Barnes will transport 100gm of MEKP, but bigger quantities incurs a hazchem charge apparently.

So, I can pick up some stuff from there, get some stuff delivered cheaper from Armsmodelit than Barnes, but only from Barnes can I get it all from 1 place, as being road transport, there's minimum charges anyway.
