Danlake Posted October 16, 2017 Report Share Posted October 16, 2017 Hi all, Expanding our filteration setup on our Red Sea Reefer 250 with a small refugium for baby fry. As the space is rather limited in the cabinet the tank needs to be custom made with size around 30 x 20 x 40 cm (in clear cast acrylic). Got a quotation for a complete build from a NZ company for 500$ Thought that was rather expensive! so instead I will get the panels pre cut (150$) and do the assembly my self. I thought the build itself would be the difficult part, but appears getting the acrylic solvent is the hard bit... unable to find any Weld On no. 4 or the stronger one no. 40. Also tried looking for the other brand Scigrip. Noticed Scotch 3M has some products in the market here but not sure if they are suitable for acrylic bonding. So question is where do you guys get your acrylic solvent for your DIY tank builds? Thanks! Best Regards Lasse Quote Link to comment Share on other sites More sharing options...
livingart Posted October 16, 2017 Report Share Posted October 16, 2017 Weldon number 16 here. http://www.anythingacrylic.co.nz/anything-acrylic/accessories/acrylic-cement/ Use of acrylic is fairly rare in nz at this stage. Quote Link to comment Share on other sites More sharing options...
Danlake Posted October 17, 2017 Author Report Share Posted October 17, 2017 Thanks, but as it has to be watertight tank Iam looking for a solvent to melt the acrylic. As far as I know no. 16 is more of a glue type used for rough project or repairs. Seems odd there is no off the shelf product a available down here.

alanmin4304 Posted October 17, 2017 Report Share Posted October 17, 2017 All the plastic "solvent cements" are the particular plastic dissolved in a suitable but differing solvent. They "weld" the plastic as the solvent evaporates. Quote Link to comment Share on other sites More sharing options...

Danlake Posted October 18, 2017 Author Report Share Posted October 18, 2017 Hi all, Thanks for replies. I finally managed to find a local distributor selling an equivalent Australian product similiar to Weld On no.4. You can purchase small 100ml bottles: https://www.awardplastics.co.nz/shop/Plastic+Fabrication/Adhesives++Cleaners/Solvent+Adhesives/Acribond+105.html For larger tanks they recommend a stronger adhevise (2 components mixtures), but for small tanks/sump this should be adequate.
