Alumilite Explains: Epoxy Heat Resistance vs Heat Deflection Temperature
Вставка
- Опубліковано 8 сер 2024
- Unsure what the heat resistance of epoxy is, or why it matters? What about heat deflection temperature?
In this newest explains video, Jordan walks through the heat ratings for Alumilite epoxies compared to each other and our competitors. Learn a bit about how heat resistance is calculated, and what the heat deflection temperature of resin actually means.
No more worrying about your epoxy melting in a hot car. We've got an explanation for you, and we're here to help.
What else do you want us to explain? Let us know in the comments below!
In this video we provide the acronym ASTM as the Automotive Standardized Testing Method - it actually stands for the American Society for Testing Materials. We stand corrected and apologize.

These videos are So helpful! I come back and re-watch often as I don't use the info often enough to memorize it, however it's required at times and would be in a mess without them. Thank you!
I’ve been searching and reading in the internet about the safety of cured resin ashtray, & how much degree I could match my thermochromic materials with other projects, ‘never thought I would find my answers in UA-cam video,
❤Thank you for this.
Loving these little science education videos...... Very helpful info. Thank you for making them! 🙂
Thanks so much for watching - we're glad you enjoyed it!
Are those temperatures in degrees Celsius or Fahrenheit?
I've been working with epoxy for over a year now... why haven't I been following you guys until now. Lol
Another great video!! Thanks for putting out such great information!!
Thank you so much!!
Good info to know! Thanks.
This is why I Love and will always use Alumilite. They give info, they do not BS, and I can learn and better utilize their materials for my off the wall projects, because I know what they know now. S'wild man.
Great Vid, Im trying to replicate an interior car dome light cover... what epoxy resin can you recommend that stands up to the interior heat which can go higher than the heat deflection of 130F?
I love all the resin education videos! Is heat reflection temperature the baseline of how much heat an epoxy can be subjected to before it starts to release fumes?
Please make a Explain video on Durability and Strength of Epoxy Resin. Please clear our doubts. Thank You 😊
It's in the works!! Keep the great ideas coming!!
Ever learning. Thanks! 8-)
We're happy you liked it!! :)
Also, there must be fillers that increase the HDT? Not sure if silica alone does this. Does compositing by infusion of glass or carbon fibers as opposed to layered over woven fabric layers, increase HDT or still only modulus and tensile strength?
Im trying to build a lava lamp out of epoxy, and wanted to know if it gets it as hot as 150 for a few hrs a day, and many years, will the color change?
I have noticed the trend of applying heat with a torch or heat gun to remove bubbles after pouring. I am curious how much momentary heat Clear Cast can tolerate directly after pouring?
Can this resin be casted in a silicon mold?
Is it resistant to wax heat resistant?
I want to know what clear resin will I use to make molds of fog light lenses. Original is glass, item gets quit warm. I would assume that I will use the one that will have the highest head deflection temperature. but I also would need one that has the clarity of glass.
For this we would recommend using our Alumilite Water Clear or (if you're worried about heat) our Alumilite Clear Slow. With both products you'll want to use a pressure pot - Water Clear will have the most clarity but Clear Slow will have a better handle on the heat.
So I can make a ACC mold and inject melted plastic into it and the mold will not melt 180°. Is this right
I'm curious how you prepare your test specimens for HDT testing.
That is a great question! All of our testing is done in a lab at a different location - if you reach out to our customer service team at info@alumilite.com, they may be able to get you that answer!
Hello, can HDT of resin be increased with post curing ?
The heat deflection temperature and the heat resistance won't ever change, though post curing will just speed up the overall curing process.
i have a question that non of the channels i have seen have answered... what epoxy would be best for places or countries that have heatwaves up to 50C degrees
You would want an epoxy with a pretty high Heat resistance. Our Amazing Clear Cast epoxy has a heat deflection temperature of 130°F (about 54°C) so it should be able to handle those high heatwaves - though it may start to get slightly soft/bouncy at those high temps, it should return to normal once cooled down! You find it here: www.alumilite.com/resins/amazing-clear-cast/
I was just wondering about this very subject, and stumbled across your video. Thank you!
So it looks like I can put an Amazing Clear Cast cast in boiling water for a bit, and it will be pretty okay after I take it out and it cools. I assume temperatures are in Celsius...
Hi Brian - not sure what you mean about boiling water. What are you looking to do with Amazing Clear Cast? Also, all temperatures used in this video are in Farenheit. Let us know if there's anything else we can help you clarify!
@@AlumiliteCorporation Oh... good to know.
Never mind. I was trying to think of a way to burn away an inclusion (such as made of wax) leaving a negative space in the Clear Cast, but I realized the heat of the curing resin would probably be hot enough to ruin anything like that. Stupid idea. Sorry.
@@brianlindsay9097 There are no stupid ideas! Brainstorming is how awesome projects come to be!! Keep thinking outside the box!!
Can u recomend high temperature resin? I want make headlamp cover
Pleaseee reply🙏
How much heat can us resin stand up to?
Does it mean we cant use rasin container for candle , as the vandle will burn too hot , container will melt!!!
Yes we do not recommend putting any flames or extreme heat next to resin
Is this resin good for coasters? I'm looking for a great quality resin that can withstand the heat of hot mugs/cups.
Yes.
It depends on which resin you’re talking about! Our Amazing Clear Cast epoxy and our Amazing Clear Cast Plus epoxy are both perfect for making coasters!
Best one for coasters?
Amazing Clear Cast epoxy is usually our go to!
Nice. Could you reccomand any resin with HDT around 200 C degree? My target is casting 3d printed parts in a resin to use these parts in an heated chamber (they should also have decent mechanical properties, at least comparable to PLA but, unlike it, keep them at 150-200 C
So none of our resins have HDTs above around 130°F. The Heat Resistance of most of our epoxies is up the 400°F range but this is when permanent damage will occur.
@@AlumiliteCorporation Thanks for the answer. 130F is about 54 C so still no advantage vs ABS. maybe also 300 F might be enough, but as application is mechanical it should also keep mostly the shape (and double the HDT seems it would definetly deform). I will figure out something else. Best regards.
I’m looking at coating printed parts with high temp coatings and just need the part to survive the curing process.
Did you ever find a solution?
I too am looking for a resin top coat that will protect from items around 300f being in direct contact. Anyone find one?
Pls tell me which metal does not heat on fire. Like i through it on fire in an hour but the metal is still normal
Not sure what you mean here - we don't work with metals. We sell resin silicone mold making rubbers and resin casting supplies.
Can you tell me when the UV resin will be back in stock? I'm waiting anxiously! Thank you so much!
We're hoping it will be back in stock in the next few weeks!!
What unit are you talking in???
All of our temperatures are in Fahrenheit!
So there's obviously a big gap between HDT and TR. HDT would be similar to a plastic's glass transient temperature, right? So my main question is, what about that 300+ degree gap in temps? A curve would be much better suited showing the transient to failure exposure times. Such as, exposure to 500f will result in full failure at 10 seconds exposure. What do we get for say, 5 or 10 minutes exposure at 300 degrees? It seems like it would deform permanently yet not catastrophically fail.
Ideally there'd be a video showing timelapsed identical projects at 100, 200, 300, 400, 500 maybe 5 second intervals over an hour. Also, the required cooling temp to reach to exit glass transience.
Thanks! Pretty "cool" information...
Thanks for watching, Lewis!! 😂

F° Aaaagh 😑 any way what resin withstand pressure and heat ?
Assuming it's fahrenheit?
Correct!
It’s not Automotive, it’s American Society for Testing and Materials.
Thank you for the correction - we were given some inaccurate information about the topic. We have added a note in the description addressing the mistake!
@@AlumiliteCorporation Sorry but you still have it wrong. The organization name is now "ASTM International".
I hope this is measured in Celsius, not Fahrenheit.
100 degrees in what scale? DOH...
ASTM stands for American Society for Testing and Materials NOT Automotive standards testing method.
Yes, we have a disclaimer in the description noting the error!
No, No, No! ASTM stands for American Society for Testing and Materials. This organization has nothing to do with the automotive industry. Please stop confusing folks!!!
You are totally right, Mike! We were given incorrect information and apologize for sharing that. Thank you for correcting us and providing us with an opportunity to do more research on the topic!
