2,4,6-Trimethylbenzoyldiphenylphosphine oxide ise sebediswa haholoholo bakeng sa enke ya ho hatisa skrineng, enke ya ho hatisa lithographic, enke ya ho hatisa ya flexographic, le dikobo tsa patsi. TPO e ka phekolwa ka botlalo hodima dibaka tse tshweu le tse nang le pigment e ngata ya titanium dioxide. E sebediswa haholo dikobong tse fapaneng, ka lebaka la tshebetso ya yona e ntle ya ho monya, e loketse haholo bakeng sa enke ya ho hatisa skrineng, ho hatisa ka tsela e bataletseng, enke ya ho hatisa ya flexographic, le dikobo tsa patsi. Kobo ha e tshehla, phello ya post polymerization e tlase, mme ha ho na masalla. E ka boela ya sebediswa bakeng sa dikobo tse bonaletsang, haholoholo e loketse dihlahiswa tse nang le ditlhoko tse tlase tsa monko. Ha e sebediswa e le nngwe ho di-polyester tse sa tlatswang tse nang le styrene, e na le bokgoni bo phahameng ba ho qala. Bakeng sa ditsamaiso tsa acrylic ester, haholoholo ditsamaiso tse mebala, hangata di hloka ho sebediswa mmoho le di-amine kapa di-acrylamides, mme di kopantswe le di-photoinitiator tse ding ho fihlella ho fola ka botlalo ha sistimi. Di loketse haholo bakeng sa ho fola bosehla bo tlase, ditsamaiso tse tshweu, le dikarolo tse teteaneng tsa filimi.
