frequently asked questions
Why epoxy resins?
Epoxy resins have very good adhesion and load-bearing properties. They are free of solvents and can also be processed under sunlight. Cured epoxy resin laminates are characterised by a high water vapour density and are therefore the ideal material for areas with permanent water exposure.
Can I also get different quantities?
Yes, no problem! Simply add individual components to the shopping basket and order. Alternatively: send a short enquiry by e-mail or use the contact form.
What weather conditions are suitable for such a project?
Temperatures between 15-25 °C and a maximum humidity of 70 %, as well as sufficient air circulation are optimal. In general, epoxy resins are not sensitive to sunlight during application, as is the case with polyester resins, for example. If necessary, you should have a cover ready to protect the fresh laminate from rain, dust or similar. For larger and longer-lasting projects, it is generally advisable to construct a kind of tent roof.
Can the HP-E80FS be directly applied to metal?
Yes,
HP-E80FS will adhere directly to metal if the surface is properly pre-treated. Pre-treatment: Sand the metal and clean with acetone. Please refer to the data sheet.
What residual moisture may the substrate have?
HP-E80FS can be used on substrates that still have a residual moisture of approx. 6%.
Is the coating dangerous for my fish?
If our processing instructions are followed, the cured material does not release any substances into the water and is therefore not critical for humans or animals.
Is chlorine pollution or the addition of salt problematic?
If the dosage instructions for the chemicals used for swimming pool hygiene are observed, it is not a problem. If the dosage is too high, the surface or the colour may be affected or changed.
The mixed HP-E80FS is relatively viscous, can I still dilute it?
Yes, it can be thinned with up to 10% thinner
HP-XB, so that it is easier to brush and therefore it penetrates better into the pores.
Within what time do I have to apply the next coat?
Basically, the next coat should be applied as soon as the previous one can be walked on. At approx. 15-20°C, this is possible within approx. 12 hours. The next coat should be applied within 24 hours (at approx. 20°C) at the latest. After that, an intermediate sanding is necessary. This applies to both the primer and the top coat system.
Why does HP-E80FS smell slightly more than other epoxy resin systems?
The hardener contains components that cause a slight aminic inherent odour. It is comparable to an ammonia-like inherent odour.
Is the HP-E30TDS UV stable?
Unfortunately, epoxy resins do not have particularly good UV stability, so they can fade over time when exposed to strong sunlight. To protect them, a clear top coat of
HP-BEL91 UV stabiliser can be applied. Alternatively, our PU topcoat
HP-PUR-PLUS can be used for coating. This system has a particularly good UV stability and can be supplied according to RAL.
Is the HP-E30TDS also available in other colours?
Yes, our epoxy resin top coat systems can be supplied in various colours or are available colourless plus various colour pastes similar to RAL. Alternatively, you can use our PU top coat
HP-PUR-PLUS (delivery according to RAL possible) for coating.
How long do I have to wait before I can add water?
The entire laminate structure (incl. epoxy resin top layer or top coat) must cure for at least 7 days at 20° before the first exposure to water. Higher temperatures over a longer period of time can shorten this time. However, a reliable statement on the time reduction cannot be given due to the wide variety of conditions.
Can I get advice by phone during the procedure?
Yes, of course! Our team is also available at work hours and can advise you by phone.
