Customer Reviews
This was my first attempt at casting parts in a silicone mold. I found the resin to kick off really fast, especially in the afternoon Texas heat. That created voids in my parts. I started working early and I achieved better results. Newly cured parts seemed a little too flexible for what I wanted, but letting them sit overnight got the results I was looking for. Pretty satisfied
Due to the morons at FedEx giving my order the Grand Tour of the lower 48 states, I haven't had the opportunity to try this product personally. I know it will do the job perfectly once I have it.
Great product, easily casted, gels in 2-3 min. Demolds in 30 min or less. This product renewed my wearing and depressing prototyping while using inferior products. This material enabled me to creat a very strict tolerance part, with bubble free glass finishes. Wish I would have discovered SRC products sooner
Bought the product as a last gasp. Desperation move for a very difficult application. Used it for the first time and I’m beyond happy with the results. Mixing was easy and so far the parts work perfectly. Long-term durability will be my only remaining question.
I have made many ball mounts for my GoPros and bushings for my cars and motorcycles. I have yet to figure out how to eliminate all the bubbles but still more than good enough for my applications.
