Hello!
I bought high density polyurethane foam, 200 kg m3, it is supposed to be suitable for depths of 100 meters, I need it for 50 meters, so I think I will not have a problem, the question is, according to what I have read, high density foam is still porous and if I do not seal it one day I could have problems related to the change of its properties, also from what I can see when touching the foam, it releases small particles, the solution would be to seal it with some type of product, on your page there is a section in which you recommend a few brands of sealants, attached:
Foam Surface Sealants
• MV85LE Mold Sealant + Release (Meguiar’s USA)
• ZYVAX Sealer GP (ZYVAX Inc.)
• DURATEC Polyester Sealer (Hawkeye Industries)
• Sanding sealer for wood products (various
manufacturers)
• Concrete sealers (both water and
solvent-based types)
• Varathane® Diamond Finish (Flecto Company)
I live in Europe and I can’t find distributors within the European Union for the products you recommend. I would need to know about similar products within the European Union, generic or specific.
Can you help me or guide me on the best way to seal the polyurethane foam? They are small pieces (35mmx35mmx35mm) which I don’t want to increase the volume or geometry, preferably I think it would be better to apply it with a spray or air gun but if this doesn’t exist I could also apply it with a brush.
In other forum topics I have seen people who have applied Epoxy resin but in the recommendations I don’t see anything similar, so I want to make sure of the best method to be able to safely and comfortably seal the machined pieces of high density polyurethane foam.
Thanks!!!
