It’s made on the Central Coast NSW, one of the reason we use acrylic in our mix is for the Uv protection. Think of Perspex that is an acrylic resin. Also most external house paints are acrylic.
PMMA is UV stable and very clear plus strong and once cured very good wear resistance .
Before we brought to the market we painted normal paving stones (one coat) with all the leading epoxies and put them outside left them there 24/7 for a year after a year of rain hail and shine only ours and one other still had a covering and after 2 years we were the only one that still had (just) a cover.
Sounds good.....I'll grab some soon and have a play ......the MSDS will be interesting .
