    Tough Cast 65D Black

    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.

    65d tough cast

    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

    First time

    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.

    Great stuff

    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.

    Great resin

    Great resin with excellent strength! Semi flexible in thinner cross regions but ridged in thicker pours. My go to resin! Customer service from specialty resin is top notch aswell! Highly reccomend the tough cast 65d black

    TOUGH-CAST 65D BLACK

    Overall the product was easy to work with and was very strong but I was not expecting it to flex as much as it does. Also I ordered Black and it is clearly not black the bottles clearly say Black on them I asked the question but no has resonded back

    I have used other products from SRC and have been happy with them but I’m most impressed with Tough-Cast 65D. I used it initially to duplicate hand grips for dumbbells. They came out identical to the factory originals. The casting went quick becaus

    It worked so well that this is my second order of Tough-Cast.
