Tikanga Whakapūngao Pūtake Totoka I te tau 2014, i pūrongohia te hanganga o te hydroxypropyl acrylate HPA mā te whakamahi i te pūtake totoka hei whakapūngao mō te wā tuatahi i te kāinga me tāwāhi. Ahakoa ka wikitoria ngā whakapūngao pūtake totoka i ngā ngoikoretanga o ngā whakapūngao tuku iho, pērā i ngā tukanga uaua i muri i te maimoatanga me te parahanga taiao, i te wā o te tauhohenga, ka āraia ētahi pore o te whakapūngao pūtake totoka e ngā ngota hua nui, ā, ka whakaitihia ngā pae hohe whakapūngao, ā, ka iti rawa te hua o te hydroxypropyl acrylate HPA. Me rangahau anō te whakamahinga o ngā whakapūngao pūtake totoka i roto i te hanganga o te hydroxypropyl acrylate.

Mā te pai o te tauhohenga me ngā āhuatanga hanga kiriata, ka whakarei ake te Hydroxypropyl Acrylate HPA i te mahi me te pakari o ngā hua ahumahi.
