Cholinga cha kafukufuku watsopano chinali kuwunika momwe mavalidwe amakasi amakhudzidwira komanso makulidwe pamachitidwe amakina a makina omalizitsira matabwa a UV-curable multilayered.
Kukhalitsa komanso kukongola kwamitengo yamatabwa kumachokera kuzinthu zomwe zimagwiritsidwa ntchito pamwamba pake. Chifukwa cha liwiro lawo lochizira mwachangu, kachulukidwe wopingasa kwambiri komanso kulimba kwambiri, zokutira zochizika ndi UV nthawi zambiri zimakondedwa ndi malo athyathyathya monga matabwa olimba, matabuleti ndi zitseko. Pankhani ya matabwa olimba, mitundu ingapo ya zowonongeka pamtunda imatha kusokoneza malingaliro a mankhwala onse. M'ntchitoyi, makonzedwe ochiritsira a UV omwe ali ndi mabanja osiyanasiyana a monomer-oligomer adakonzedwa ndikugwiritsidwa ntchito ngati chovala choyambira mkati mwa matabwa amitundu yambiri. Ngakhale topcoat idapangidwa kuti ipirire zolemetsa zambiri zomwe zimagwiritsidwa ntchito, zotanuka ndi zolimba zapulasitiki zimatha kufikira zigawo zakuya.
Panthawi yophunzira, zinthu zakuthupi monga kutalika kwa gawo lachidziwitso, kutentha kwa magalasi ndi kachulukidwe kameneka, mafilimu odziimira a mabanja osiyanasiyana a monomer-oligomer adafufuzidwa. Kenako, kuyesa kwa indentation ndi kukanika kukana kunachitika kuti amvetsetse gawo la ma basecoats pamayankhidwe amakina a zokutira zamitundu yambiri. Makulidwe a basecoat ogwiritsidwa ntchito adapezeka kuti ali ndi chikoka chachikulu pamakina amakanidwe a dongosolo lomaliza. Palibe kulumikizana kwachindunji komwe kunakhazikitsidwa pakati pa basecoat ngati mafilimu oyimira okha komanso mkati mwa zokutira zamitundu yambiri, poganizira zovuta zamakina otere machitidwe angapo adapezeka. Dongosolo lomaliza lomwe limatha kulimbikitsa kukana kukanda bwino komanso modulus yabwino ya indentation idapezedwa kuti apange mawonekedwe owonetsa kufanana pakati pa kachulukidwe ka netiweki ndi elasticity.
