## Questions & Answers

**Q: How hot is this get when it is curing?**
A: The exothermic heat the MAX MCR produces during cure is based on the amount or volume of the mixture that is allowed to cure. For example, 1 cup of the mixed MAX MCR will cure within 25 minutes and can produce temperatures of up to 200 to 225 degrees Fahrenheit. Curing 1/2 that size will exotherm less than 180 degrees Fahrenheit and cures to the touch in 45 to 60 minutes. 

We also offer a potting compound for a large volume potting. It offers a longer working time, low exothermic heat, and is thermally conductive to reduce heat build-up. The heat produced for a 4 cup volume is less than 160 deg Fahrenheit.  Please check out our MAX TPC A/B, here is the link;

Check out the description area for further details. Thanks.

**Q: Will this cute at outside temperature (100f)?**
A: Hello,
This resin system, MAX MCR A/B is a room temperature curing resin. The ideal curing temperature is between 65°F to 95°F.  Upon cure, MAX MCR A/B will withstand outdoor temperature exposures of up to 190°F. Here is a video demonstration of the MAX MCR A/B showing its typical mixing and casting application.

The ambient temperature during mixing and curing was 75°F and the MAX MCR cured rigid after 18 hours at the same temperature. Here is the technical data sheet where more engineering data is published;

Thank you.

**Q: What material do you recommend making a reusable mold from?**
A: Hello, 
The best reusable mold material is silicone RTV molds. Here is a link to pictures of this resin system used to encapsulate a high voltage UV lamp base using a Shore Durometer 30A silicone mold that was fabricated specifically for this purpose;

You may also find premade silicone molds by searching AMAZON for 'silicone molds'. This molds are typically used for soapmaking and candle wax casting. They come in different shapes and sizes that may be suitable for your application. Here is an example;

Thanks and I hope this helps.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good viscosity
*by S***Y on January 29, 2020*

I like this over the previous stuff was using because this is a thinner viscosity...pours easier and quicker. Get more done in less time since not waiting for the pour. Overall seems to work well for electronic encapsulation.

### ⭐⭐⭐ product review
*by C***S on April 6, 2023*

Bought two sets of this kit. First set was poured and had to leave it over night. Product was mixed continuously for 10 minutes. after leaving it overnight the product hardened but did not completely cure overnight. some areas are still tacky and leave residue if touched. Second kit was also mixed continuously for 10 minutes. After 52 minutes mix started to heat up and within seconds it was steaming vigorously. By the time I attempted to pour (literally 53 minutes of mixing) it hardened mid pour instantly. Seams like the second batch is working properly but after the 30 working time the material will flash and harden instantly.

### ⭐⭐⭐⭐⭐ Five Stars
