General Information about Resin8 Heat-Resistant Epoxy Resin
This resin is specifically designed for coating, although works really well as a clear top for coasters and placemats. Resin8 Heat-Resistant Epoxy Resin will be touch dry in 24 hours, but needs a full 7 days to reach optimum heat-resistance properties, provided you mix the minimum recommended amount of 200g. If you do mix less than 200g total, you will need to allow more time for the resin to reach full cure.
NOTE: Please be aware that adding anything to epoxy resin will change its properties and may reduce its non-toxicity. If you are adding alcohol inks DO NOT use a flame to remove bubbles, as alcohol is flammable. Resin8 Heat-Resistant Epoxy Resin is designed to be used clear. The addition of pigments, powders, alcohol, silicone and other elements will alter its chemical properties, potentially reduce its non-toxicity and affect the final cure time. We advise a final clear layer of Resin8 Heat-Resistant Epoxy Resin is applied on top of the finished piece to boost it's heat-resistance.
Resin8 Heat-Resistant Epoxy Resin has been certified by the ASTM (American Society for Testing and Materials) as non-toxic when used as directed and conforms to ASTM D-4236. It contains no VOCs, no solvents and doesn't give off fumes when used at room temperature. It is non-flammable and has a very mild odour and therefore safe for home use.
Health & Safety
Resin8 Heat-Resistant Epoxy Resin is a modern formulation of the safest epoxy chemicals available. However, all epoxy resins are chemicals and they do come with Health & Safety implications.
Here are the important downloads which we advise you to read before you start working with this resin:
More information on health & safety while working with epoxy resins can be read on our Health & Safety page.
- You MUST wear nitrile gloves (or use a specialist resin barrier cream on your hands)
- You MUST wear a respirator when sanding partially-cured resin
- Ensure you work with this resin in a well ventilated room
- We advise you to wear safety goggles
- Avoid skin contact
- We advise against eating, drinking or smoking while working
- In case of eye contamination wash with plenty of water for 15 minutes and consult medical advice immediately
It is CRITICAL that you follow the instructions accurately. Do NOT change the mixing ratio - this will alter the properties of the resin and cause it to remain tacky.
This resin is fairly runny and can be easily mixed. It is less effective when mixed in small quantities so we advise you to mix at least 200g of this resin. Use 2 parts resin to 1 part hardener by volume or weight (2:1) to ensure a hard finish once set. Use separate, clean volumetric mixing cups for each part. We advise you to pour the hardener first and then the resin into one clean, larger cup. The mixed components should be thoroughly stirred for 3 minutes to ensure an even consistency - this is a long time... set a timer on your phone.
Resin8 Heat-Resistant Epoxy Resin has a pot life of around 60 minutes, depending on the temperature of your workspace. If you prefer to weigh your resin, use accurate digital scales (not the old fashioned kitchen kind) and use the ratio of 100g resin to 50g hardener pro-rata.
This resin is designed to be used as a clear coating but it can also be coloured with our any non-water based pigments and powders on our site - opaque, transparent, metallic, etc. Apply by brush, roller or pouring. Temperature should be between 18 to 25ºC and humidity level below 70% (i.e. do not use in a room with drying laundry). A 2:1 mix will provide a hard, glossy finish. Make sure your resin piece is level. Pop any bubbles by hand using a cocktail stick, or use a heat gun or naked flame for a couple of seconds to aid bubble release. Avoid dimpling by holding the blowtorch or heat gun at least 30cm away. Use silicone dispersion media such as resi-BLAST to create lacing and cellular effects.
If cured at 20ºC and used as a coating, this resin should be touch dry within 24 hours and be fully cured after 7 days. We advise you to cure your resin pieces in a dust free environment, and keep in the dark for as long as possible. Resin8 Heat-Resistant Epoxy Resin needs 7-10 days to reach maximum cured properties and temperature resistance. The addition of pigments (inks, powders and pastes) as well as other resin additives (resi-BLAST, silicone, lubricants, alcohol or solvents) will lower its temperature resistance - because pigment substances themselves have a very low temperature threshold. The higher the addition rate of pigments & additives which are added or mixed into Resin8 Heat-Resistant Epoxy Resin, the more the thermal withstand of the cured mass is lowered and compromised. In this case, we recommend a final clear topcoat is applied on top of the pigmented layer to bolster its resistance against hot objects placed on it.
