N'ihi mgbanwe dị ike nke njikọ disulfide, agbụ ndị a na-agbaji mgbe niile ma wughachi ya n'okpuru ọkụ ọkụ ultraviolet, na-agbanwe ike ọkụ ultraviolet ka ọ bụrụ ntọhapụ ike okpomọkụ. Ihe na-acha odo odo nke polyurethane na-akpata site na ultraviolet ìhè irradiation, nke na-akpali njikọ kemịkalụ na ihe polyurethane ma na-akpata nkwụsị nke njikọ na mmeghachi omume nhazigharị, na-eduga ná mgbanwe nhazi na ịcha nke polyurethane. Ya mere, site n'iwebata njikọ nke disulfide n'ime akụkụ nke polyurethane nke mmiri na-adabere na mmiri, a nwalere ọgwụgwọ onwe ya na nkwụsị nke odo nke polyurethane.
