Hello to everyone of the community!


I want to share with you a very good source for EPOXY!:

at [B]http://www.breddermann-kunstharze.de/[/B] you will find all that is
necessary to make stunning micarta!

Navigating to: - Epoxidharze/- Deckschichtsysteme/ Versiegelung

you will find a product named E40D.

E stands for Epoxy,
40 minutes pot-time
D stands for Deckschichtsysteme..

It is clear like water, highly viscous, pretty much resisting
UV radiation and most of all:

A LOT LESS STINKY THAN POLYESTER resins!!!

Frequent measurements guarantee that there is far less emission
of butyl alcohol that there would be allowed to be (only 2ppm!)

And now the most interesting aspect:

IT IS AVAILABLE AT A STUNNING PRICE!

E40D 750 g: 14,29 €inkl. Tax. + shipping
E40D 1,5 kg: 22,90 €inkl. Tax. + shipping
E40D 3,0 kg: 36,90 €inkl. Tax. + shipping



WAY CHEAPER THAN ANY POLYESTER offered!

Mr. Breddermann is a chemist, producer, filler and retailer of his own
products. And he´s a friend of mine. And he´s willing to support the
slingshot-community:

If you want to order any of his products, here´s the deal:

If you mention "BeMahoney" or
"Slingshot-Channel", you will get 3% off of the
prices offered at
http://breddermann-kunstharze.de/.
Just like that.


I hope you find this helpful and will enjoy the stunning
high quality micarta made of that as much as I do!

Greetings to everyone,

Be

Good for you Be!

This is what I found on english sites selling E40d. Sealing for metal, wood, plastics, concrete, screed
  • Cause clear, non-gluey surfaces
  • Higher resistant to UV radiation, very slight yellowing
  • Excellent mechanical properties, high impact strength
  • Osmosis protection, filler for wooden porosities
  • Carbon look laminates
  • Water barrier layer, surface protection, varnish

I tried the link, but I got "Page not found"

Does he ship to the US? If so, any idea how costly that would be? I'd like to get some good epoxy, but the stuff I find here is really expensive, even for smaller containers.

If anyone in the US knows a good source of good epoxy that is reasonably priced, I'd love to here your suggestions. I'd love to get some GFlex, but it's a bit more than I want to spend at the moment. Christmas gifts and all that ;)

Nothing is easy!

Hey everybody!

Could be seen as a disappointment,
to accept that I still have to learn a whole lot about
lamination processes, but being old enough to know
that nothing is easy, I´m pleased to have made the
first steps.

Just in case you might like to know:
Working with that E40D epoxy resin is awesome!
It smells way, way less than ordinary paint -
due to the fact that no solvent has to evaporate,
I gave it a try to work with it indoors, not even
wearing a mask, because what the measurement
showed really seems to be true: only very few
particles get into the air (far from MAK-limits /
critical concentrations).

At roughly 19°C the pot-time is indeed very comfortable,
I laminated a pile of 16mm! thickness - which was
strategically a bad decision concerning bubbles..
with not a single moment of stress or hectic pace.
I will have to get myself accurate electronic scales,
and I will be looking for a little evacuation pump at the bay..

But hey: after having built a 14ft canoe with polyester resin
eleven years ago, I must say that the trauma I had from
that (despite using a heavy gas-mask with the right filters)
unimaginable odor is cured now.

Stepping into another universe..

Learning to walk..

Hey everyone,

I´m learning to walk: Made the first try an that epoxy-finishing
resin. And I still have to say: Awesome! This stuff cures slowly
at 20°C, but at the end it is really hard and clear like air!
The first try was with different types of paper.
Rice-paper, hemp-paper and heavy artistic papers, as well
as egg-carton and a secret ingredient :)

Greetings to everyone,

Be

This is what came out of the mold:

The new material

Then I made a slingshot out of that platter.
Before the final finish, I opened all bubbles near to
the surface, cosmetics so to say..

A new infrared-lamp I bought opened another door:
speeding up the process!- At 80°C, finally almost 100°C,
this stuff reveals super-powers ;) It cures within minutes,
which will allow to cure the finishing layers very quickly in
the future, and the hardness of the last layers is even
increasing (while the "body" of the slingshot is rather
"flexible"- in comparison)

The little bumps deriving from pre-filling the "bubbles" will have to be
sanded off, then it´s ready for the final finishing layer...

it took only 0.75ml to varnish the whole slingshot with a
non-grinding scotch pad.

Moin moin,
Unfortunately, epoxy is not a toy ...
If one wants to imitate,
Makes you before smart about the product,
read the safety data that you get from the manufacturer .....

The resins often contain the - shall we say - not health promoting - bisphenol a! And still other substances .... So ventilate - Wear suitable gloves reaction resin - note the permeation time here ..... etc.

Sicherheitsdatenblatt hier mal von R41 :

Epoxi ist leider kein Spielzeug...
Falls es einer nachmachen möchte,
Macht euch über das Produkt vorher schlau,
lest das Sicherheitsdatenblatt, das bekommt man beim Hersteller.....

Die Harze enthalten oft das - sagen wir mal - nicht Gesundheitsfördernde - bisphenol a !!! Und noch andere Stoffe .... also lüften - Reaktionsharz geeignete Handschuhe tragen - hier die durchdringzeit beachten..... usw.

Hey Thorsten,

thanks for taking care!- Mr. Breddermann IS the producer!-
And he will gladly give answers concerning his products.

I talked to him about that fuming issue; He was honest
enough to say that he legally has to say that wearing a
mask and ventilation is very important.

I asked him about working outdoors with that stuff;
he said that he personally would work indoors, and
among not using a mask, he pointed out that the emissions
of his products are frequently measured.-
If someone works with 1 kg! of that stuff at 20°C,
there will be 2! ppm of those butyle alcohols, if I´m
remembering right, 200ppm is the legal boundary value.

(- working in that fume for 8 hours, 200 days p.a. ..)

You are right about Bispenol A (and F), but those need to
get into your body (like when drinking water from plastic
bottles) to have that endocrine effect. (A shocking
documentation about plastics is "Plastic Planet" from an
austrian movie-maker, I highly recommend that one!)

Greetings to Frankfurt,

Be

He certainly send methe technical data sheets;
Might be good to have those.

Hey NyamNyam,

Nur keine Panik! Das Zeug heißt E40D - 40 Minuten
Topfzeit!- Danach ist es immer noch sehr weich!
(eigentlich noch "flüssig")

Die Aushärtezeit (alle Dokumente müssten im Thread
verfügbar sein) ist 20 Stunden. Auch dann ist das Harz
noch weich (Fingernagel macht Spuren..)

Das Harz ist ein Deckharz!- Das Tolle ist, selbst dicke
Papiere werden völlig durchtränkt! 10°C Temperaturerhöhung
halbieren die Aushärtezeit (RGT-Regel).

Das heißt, bei 30°C dauerts 10 Stunden;
bei 40°C dauerts 5 Stunden
bei 50°C dauerts 2,5 Stunden
bei 60°C dauerts 75 Minuten

Ich nehm das Zeug wirklich auch zum "Lackieren",
der Ofen in der Werkstatt (besser nicht den in der Küche..)
ist dabei Gold wert!

Das Zeug wird nach ca. 1 1/2 Tagen knüppelhart!
(Höhere Temperaturen beim Aushärten steigern die
Endfestigkeit..)
Ich bilde mir ein, daß trotzdem die Nötige Zähigkeit vorhanden ist,
um nicht von "spröde" sprechen zu müssen.

Theoretisch kann man noch viel heisser härten (max 120°C)
- z.B bei Holz dehnen sich im Holz "gefangene" Gase dann
aber stark aus und machen Blasen..

Also nur Geduld, das wird!

Liebe Grüße,

Be
