Kuwonongeka kwa mphira-yochiritsidwa kwambiri{1}}kutentha kwambiri kwa mphira wa silikoni kumatheka kudzera muzowonjezera za hydrosilane. Kutentha, magulu a silane mu hydrogen{3}}yokhala ndi mafuta a silikoni ndi magulu a vinilu mu raba ya methyl vinyl yaiwisi amakhudzidwa ndi chloroplatinic acid, potero amapanga mtanda{4}}wolumikizana:
Kuwonjeza{{0}ochiritsidwa kwambiri-rabala ya silikoni yotenthedwa ndi kutentha akhoza kugawidwa m'magulu amodzi-ndi mitundu iwiri-yamitundu iwiri. Chimodzi-chinthu chowonjezera{{6}chochiritsidwa kwambiri-labala ya silikoni yotentha kwambiri ndi mtundu wa labala wa silikoni womwe ukukula mofulumira kwambiri. Chifukwa cha kukhalapo kwa sulfidation inhibitors (monga, etc.), kukhazikika kwake kosungirako kumatha kuyambira miyezi iwiri mpaka miyezi 12. Pawiri ya mphira yomwe imagwiritsidwa ntchito potulutsa imatha kusungidwa mokhazikika kwa miyezi iwiri, pomwe mphira wopangira mphira amatha kusungidwa kwa miyezi 12. Nthawi yosungira{15}magawo awiri-ochiritsidwa kwambiri{17}}rabala ya silikoni yotentha kwambiri ndi yotalikirapo kuposa{18}}rabala imodzi. Kusakaniza kwa zigawo ziwirizi kungakhale 1: 1 kapena 100: 1.5.
The A chigawo chimodzi cha mphira pawiri ndi kusakaniza chiŵerengero cha 1: 1 tichipeza m'munsi mphira, crosslinking agent ndi vulcanization inhibitor, pamene B chigawo tichipeza m'munsi mphira ndi platinamu chothandizira. Mu 100: 1.5 mphira pawiri, zigawo zikuluzikulu ndi mphira maziko, crosslinking agent ndi inhibitor, pamene chigawo chapamwamba ndi mphira m'munsi ndi wowonjezera wothandizira wothandizira.
Ubwino umodzi waukulu wowonjezera-kutentha kwambiri{1}}rabala ya silikoni yotenthedwa ndi kutentha ndikuti kuchuluka kwake kumakhala kochepa kwambiri panthawi yavulcanization, zomwe zili chifukwa chakuti palibe{2}}mankhwala omwe amapangidwa pochiritsa. Komabe, popeza machiritso amafunikira kugwiritsa ntchito chothandizira cha platinamu, sichiyenera kukumana ndi mankhwala omwe angayambitse poizoni panthawi yogwiritsidwa ntchito, monga mankhwala omwe ali ndi zinthu monga nayitrogeni, phosphorous, ndi sulfure, mankhwala opangidwa ndi magulu othamanga, ndi zitsulo za ayoni monga malata, lead, mercury, ndi bismuth. Zoonadi, nthawi zina mankhwala otere amawonjezeredwa kuzinthu monga zoletsa kuti apititse patsogolo kusunga kwawo.
