Sebenzisa:

I-Benzophenone-4 i-soluble yamanzi kwaye iyanconywa kwizinto eziphezulu zokukhusela ilanga. Uvavanyo lubonise ukuba i-Benzophenone-4 iqinisa i-viscosity ye-gels esekelwe

i-polyacrylic acid (iCarbopol, iPemulen) xa bevezwe kwimitha ye-UV. Ugxininiso olusezantsi njenge-0.1% lunika iziphumo ezilungileyo. Isetyenziswa njenge-ultra-violet stabilizer kuboya, izithambiso, izitshabalalisi & nokugquma kwepleyiti yelithographic. Kufuneka kuqatshelwe

I-tha tBenzophenone-4 ayihambelani ne-Mg salts, ngokukodwa kwi-emulsion yeoli yamanzi. I-Benzophenone-4 inombala omthubi oye ube namandla ngakumbi kuluhlu lwe-alkaline kwaye unokutshintsha ngenxa yezisombululo ezinemibala.

Ukupakisha kunye noGcino:

Iphakheji: 25KG / CARTON

Ugcino: Izinzile kwipropati, gcina umoya kwaye kude namanzi kunye nobushushu obuphezulu.
