Me Again
The attached data sheet pertains to the most readily available epoxy here in South Africa. This is the UK made by
SP systems. The 115 in the data sheet was made for surfboard blanks and is said to have a slight bluish tinge.
The pot life and gel times look a little short for a first timer working alone on a great big Redbird in a 25 C
(77 F) ambient temperature. Should I bite the bullet and import a nice slow MAS or the tried and tested West?
Could one or two of the Guru’s give the specks a once over and let me know what they think?
Much obliged
Geordie.

Hi Geordie, I read the data and I'm not sure I would want to try the SP 115 even with experience. I believe
West Systems has a distributor in South Africa according to the info I found: Exaton Composites (PTY) Ltd
PO Box 38703
Pinelands 7430

The West Systems 105 resin with 207 hardener might be a better choice.

Hi Guys
The MAS brands of epoxy can be recoated (using the slow hardener)in as little as 6 hours and as long as 12- 20 hours .
We have sped it up just a tiny bit , but not reformulated.
There is still no Amine Blush on our surface.so you never have to wash the surface or worry about contamination
(we've been doing this for 15 years).
Our low viscosity hardener wets out with out having to precoat using either 4oz or 6oz
Fabrics.Look up wood song conoes to see how. Great site. so is Newfound woodworks

I don't think it sounds that scary

Our best selling hardeners are the 610 which is very fast
curing and the 606 which is slow curing. They are mixed at
a ratio of two parts resin to one part hardener. The two to
one ratio epoxies are probably the most popular because
they give a good compromise in ease of use, are low
blushing and have good overall physical properties.
I’ll give a brief description of our two to one epoxies
because these are what our customers most often request.
Depending on the job requirements, you can choose a fast
or slow hardener or a combination at no extra cost. At 77
degrees [F.] the pot life (using 3 mixed ounces) of the fast
hardener-resin mix is about 8 minutes. Three ounces of
slow hardener would give you about 25 minutes of working
time. A mixture using only fast hardener 610, can be used
down to 50 degrees F and suing only slow hardener 606,
should no be used below 60 degrees. A useful feature of
the two hardeners is their ability to be blended together to
customize a cure time for your particular requirements. We
recommend when working under 70 degrees to use a
blend of hardeners if you want a working cure within 24
hours. The majority of our customers divide their
purchase of hardeners into equal amounts of slow and fast.
