Asɛmfua "platinum-a wɔayɛ no aduru" (anaasɛ "platinum-catalyzed") kyerɛ nnuru a wɔde di dwuma de hyɛ nsu silicone rɔba den ma ɛyɛ nea etwa to, a ɛyɛ mmerɛw.

Nsonsonoe titiriw no da chemistry a ɛwɔ curing akwan horow abien so:Platinum a ɛma nneɛma yɛ kɛse (aduru a wɔde ka ho) vs. peroxide a ɛma nneɛma yɛ kɛse (peroxide aduru).
1. Nsonsonoe titiriw no: nnuru a ɛyɛ adwuma & nneɛma a efi mu ba .
Platinum curing (Ade foforo a wɔde ka ho): .
Saa adeyɛ yi te sɛ nea wɔde molecule "lego birikisi" resi dan. Platinum complex (a catalyst) ma ɛyɛ mmerɛw sɛ adeyɛ bi wɔ base silicone polymers ne cross-nkitahodi ntam. Saa adeyɛ yi yɛ nea etu mpɔn yiye na .ɛmma nnuru a efi mu ba titiriw biara mma ..
Platinum dade no ankasa nyɛ adwuma na ɛda so ara akyea wɔ silicone a wɔayɛ no yiye no mu wɔ dodow ketewaa bi mu, a asiane biara nni ho. Ɛnkɔ so nkɔ.
Peroxide a wɔde yɛ aduru (a wontua hwee-ayɛyɛde a ɛyɛ hu):
Saa adeyɛ yi te sɛ "Breaking ne Re-a ɛka bom" molecule nkɔnsɔnkɔnsɔn no kɛse. Peroxide aduru bi sɛe wɔ ɔhyew ase ma ɛyɛ free radicals a efi ase yɛ aduru. Nanso, saa porɔwee yi .Akyinnye biara nni ho sɛ ɛde nneɛma nketenkete a efi mu ba ba ., te sɛ ketone, aldehydes, anaa nsa.
Saa nneɛma yi taa yɛ "nnuru" anaa "rubbery" hua a emu yɛ den. Bere a wɔde post-production baking (post-curing) di dwuma de yi wɔn mu dodow no ara fi hɔ no, ɛyɛ den sɛ wobeyi afi hɔ koraa, na ɛma asiane a ɛne sɛ nneɛma kakraa bi bɛtu afi hɔ bere kɔ so no, titiriw bere a wɔayɛ no hyew no.
