Epoxy!
Intro:
This page is not an scientific
essay! Neither a chemical one! If you don't have a certain humor ,
please hit the Browser "Back" button ! It shall help you to
understand with what you are dealing or want to. Just a basic intro
into epoxy. For the use and different mixes please use the
appropriate page from Tips and
Tricks section , thank you ! And to make
the whole story easier from the beginning on we change the
word
Epoxy - to - Chicken
soupHope you like chicken soup
and now let's go in the kitchen to make some !
What is this stuff
?
Like it is with chicken soup you mix a lot of
stuff together, Epoxy ... or what is sold as Epoxy in most shops is
a mixture of different chemicals. Ciba is producing 2000 different
epoxies! Quite a lot for making a few thousands of chicken soup!
Each different and with other properties -or taste! So how do you
know what you get ? Guess it is the same like with the soup in the
restaurant - big surprise - you have to try it ... don't believe
that the epoxy from one supplier is the perfect for you and for
every job - what is good for wood is not good for concrete - and
vice versa ! Before every job test your resin / hardener mix if it
is suitable for your purpose, temperature in your workshop, material
where you apply it and to you in form of chemical reaction! Like you
have to find your perfect restaurant - you have also to look out for
your perfect supplier !
Where do I get the perfect
stuff ?
My honest opinion is that you have to find
him by yourself - the perfect supplier is one who has an open ear
and mind for you where you can ask questions and get answers! If you
describe him your problem - he tries to find the solution -
sometimes it's the small shop around the corner - sometimes it
is a supplier a half continent away - the basic resin from one
supplier can be modified to your need's with the correct additives
in the correct mix ... I know that if you buy a few gallon most of
them don't really care - but if you shop around - you will find some
who do and most give samples so you can test them out ! Stay in
contact with him and tell him what bugs you ... would you eat a
salty chicken soup in your favorite restaurant without telling the
waiter how lousy it was ... the same is with your resin ... you can
only get the perfect resin if you describe what you like and don't
like.
How do I know it is right
?
Here are the answers as much as there are
applications ... you have to use different resins during the year to
adapt to changes in humidity, temperature and application - except
you are doing always the same in a 100% stable environment ... lucky
you ...or perhaps boring since you can't screw up! Still an epoxy
which you apply to a concrete structure does not need flex, on a
wooden boat it should have a certain amount, for laminating
fiberglass you don't need leveling characteristics but for you're
sealing it makes a big difference if you have fish eye's or not !
Tell your supplier for what kind of applications you need it and he
might pick a good choice on the spot! Still check it out and never
throw your old mixing pot right away in the garbage can he is the
best "quality control" you have.
I use old yoghourt cups for mixing through mark the
date and leave them a week - after that the resin is 100% cured
(most of them) squeeze the pot and see how your resin behaves ...
you can learn a lot from your mixing pot.
Technical Data sheets
!
These wonderful papers come normally with
your first order ! They are more or less the Nutrition facts of your
chicken soup or the waiters comment "it's still hot - don't get
burned". Even if they look sometimes like the description of a
space shuttle part and you have no clue whatsoever is written there
... please try to look them through - they are not in the package to
fill it up but they have important info on how dangerous the stuff
is how flammable and what to use to extinguish the fire ...perhaps
read before the fire reaches your shops ceiling and have the correct
extinguisher around medical first aid might be useful if your kid
took a sniff from it or somebody stored the remaining MEK in a
sprite can with no label ..., Hand - Eye and other body part
protection ...and so on ... please read before opening the first can
- if not - it might be your last.
So guess this are enough smart words on
chicken soup and if you still need more answers, please look through
our other pages of resin - applications, resin - filler ...as they
get posted ! |
