Includes everything you need to easily and accurately mix anything between a custom sized small batch to a full 500 grams of silicone elastomer resin. Product features: Transparent / Optically Clear when mixed AND when fully cured. Two-part, 10 to 1 mix ratio. Polydimethylsiloxane (PDMS) silicone based elastomer. Good flow and spreadability when mixed. Compare to Dow Corning brand Sylgard 184. Standard curing time profile similar to DC 184. Resistant to cold and heat (up to 392ºF, 200ºC). Does not yellow or discolor under UV light. Suitabe for room temperature cure OR heat cure. Room Temperature (72ºF to 77ºF) full cure to approximately 45 Shore A hardness in 24-28 hours. Room Temperature (72ºF to 77ºF) 50% cure to approximately 20-25 Shore A hardness in 12-14 hours. Heat cure: Curing time at 212ºF is approximately 30-45 minutes (not including recommended one hour standing time at room temperature prior to heating to allow for entrained air bubbles to disappear if not using vacuum debarring).

Review: Less stiff than sylgard 184 - Works in a pinch but the elastic modulus is less than I’m used to, making hole punching unreliable. Could try a hole puncher a size up maybe
