Liquid Silicone Rubber for Molds 1:1 R PRO 30 (500 gr)

Perfect, solid compared to others I've used.

This silicone is great, durable, captures detail very well and easy to mix thanks to one side having a yellow pigment. However now that the price has gone up I will be looking elsewhere, as it is just too over priced for what you get. The bottles are a pain as you have a lot of wastage due to not being able to get everything out of them, which again with the price being what it is becomes a bigger issue. I've found an alternative over at Mouldlife and have just paid £36 plus postage for 2kg of a similar silicone.

needed 790g bought 1000g as there may have been wastage mixed it got just under 800g but after pouring lost 60g and fell short really annoyed should have had 210g left over not fall short of 60g hope i can salvage the situation when it has hardened. i mean i hope i can get the object i was trying to cast and reuse it as it was unique. we will see as for the product well so far 0 points for not being acurate to weights and measures, by the way i slit the tubes it came in to slices and scraped every reminant so i know the quantity was incorrect. If anyone wishes to use this product then may i sugest buying twice as much as you need as thats their maths but at this platinum price this will prove very expensive am very disapointed and believe in uk against law to state a weight but not provide it.

Bought this product twice and it failed to cure both times. I figured the first time was my fault as I usually eyeball my silicone mixtures by ratio and never have issues. The second time I got the scales out and did it right and it still failed to cure after a generous 40 hour setting time. Still goopy, sticky and oozing. Not sure if it's a faulty batch or what but it ruined my models and because its a consumable I can't even return it. That's almost 80£ down the pan on a lousy product.

I needed a medium hardness silicone rubber for my moulding process. I mixed the two components as recommended on the instruction label. However, even after 24 hours the mixture was still liquid. I am now left with the problem of how do I clean out my mould and dispose of this mess responsibly. Do not buy this product.

I use casting rubbers all the time and this is the worst product ever, still wet after casting 24 hours later and is not a hard rubber. The price is a complete ripoff . don't waste your money on this product

This product seems way more firm than indicated. Has next to no give when taking items out of mould. Couldn't use this item as intended. I think this would be okay for a flat mould, but not for ministries or D&D dice.

Was a great I’d use it again but pick my container I use a little better am a beginner so my fault not the product loved the colour to nice yellow mold

tres bonne qualité de produit

Ho acquistato la gomma siliconica Reschimica R PRO 30 per realizzare stampi e sono rimasto molto soddisfatto. La miscela 1:1 è semplice da usare, senza bisogno di bilance di precisione. Il tempo di lavorazione è sufficiente per colarla senza fretta, e la vulcanizzazione è rapida. Una volta asciutta, il silicone è flessibile ma resistente alla rottura, con una durezza 30 Shore, perfetta per dettagli precisi. Ho testato stampi con resina epossidica, gesso e cera, e il distacco è sempre risultato facile. in particolare ho provato a fare un battipenna per Fender stratocaster, il risultato è stato eccellente. Inoltre, è non tossica e senza odori fastidiosi. Un ottimo prodotto per chi cerca qualità e facilità d’uso. Lo ricomprerò sicuramente!

mixed well and made a very good mold

Very easy to use and fast curing.

Depuis 2019 j'ai dupliqué les semelles orthopédiques de mon podologue en TPU (Shore 95A et Shore 60A) avec mon imprimante 3D. Pour plus de confort, j'ai voulu tester avec du silicone (Shore 30) J'ai donc imprimé un moule en PLA (marque Dailyfil noir) avec une buse de 0.4mm et une hauteur de couche de 0.1mm. Les 2 parties du moule ont mis chacune 36h d'impression. J'ai alors appliqué un antiadhérent, par sécurité (Trennfix 100ml, vendu sur Amazon), que j'ai laissé sécher 10 minutes. J'ai ensuite refermé le moule avec des vis M4 avec écrous. J'ai mélangé 134g de silicone avec un rapport 1:1. Attention, ce rapport est en poids et non en volume. Il faut donc utiliser une balance (ici 67g de silicone et 67g de durcisseur). Il faut aussi prendre le temps de bien mélanger plusieurs minutes (et non pas quelques secondes !) pour que le durcisseur soit bien en contacte avec tout le silicone et doucement (pour éviter les bulles). Pendant que je coulais le silicone, j'ai tapoté à plusieurs reprises sur le moule pour faire remonter les bulles. J'ai terminé en tapant à plusieurs reprises avec un maillet en caoutchouc. Le temps de séchage indiqué est "3h à 23°C, moins si plus chaud, beaucoup plus si moins chaud". Chez moi il fait 20°C. J'ai donc laissé 7h. Le secret c'est de ne pas chercher à aller trop vite, sinon, comme je l'ai vu sur certains commentaires, le silicone reste collant, car tout simplement toujours entrain de polymériser. Au final le résultat est nickel. Pas de bulle, pas collant, se décolle tout seul, finition parfaite. On voit les traces des lignes d'impression de 0.1mm du moule, donc parfaire réplication. Le moule en PLA n'a pas du tout souffert et pourra donc servir à de nombreuses reprises. Il est cependant dommage que ce soit jaune et non pas transparent ou blanc. Car j'ai aussi testé les colorants mais la couleur se mélange. Ainsi, le bleu devient turquoise par exemple. A noter aussi que si vous utilisez un colorant, le temps de polymérisation devient nettement plus long, mais au final c'est ok.
