****************************************************
All molds are made with high quality platinum cure silicone that is suitable for casting resin or concrete. Molds with this material are made to last, however, molds will degrade over time/usage. There are many factors that determine how fast a mold degrades. Here are several things to take into consideration:
- Heat wears molds out. Using a torch on molds will damage them. Please stay away from using heat on molds!
- Slow curing resins place greater stress on molds.
- Mold releases extend a mold's life.
- Pouring thicker than the resin's recommended depth may damage molds due to heat from the exothermic reaction.
- Bubbles formed on the surface of a mold (especially 3D molds) can scrape the molds during the demolding process. Please make sure that there are no bubbles on mold's surface.
- Overstretching molds might cause permanent damage to them.
...and many more. Even though these are high quality molds, misuse can damage or degrade them.
