Ubwino umodzi wogwiritsa ntchito HPMC ngati chowonjezera mu khoma la putty ndikusunga madzi. HPMC ikhoza kukhala ndi madzi ambiri, omwe amathandiza kuti khoma la putty likhale lopanda madzi ndikugwira ntchito motalika. Izi zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito ndipo zimalola wogwiritsa ntchito nthawi yambiri kuti agwiritse ntchito zinthuzo zisanayambe kukhazikitsidwa.

Phindu lina logwiritsa ntchito HPMC ngati chowonjezera mu khoma la putty ndikugwirizana kwake ndi zina zowonjezera. Itha kugwiritsidwa ntchito ndi zida zina zosiyanasiyana, kuphatikiza ma pigment, ma fillers ndi zokhuthala zina, kupanga mapangidwe amtundu wa khoma omwe amakwaniritsa zosowa zenizeni.

Kupatula kugwiritsidwa ntchito kwake ngati chokhuthala mu khoma, HPMC ilinso ndi ntchito zina zambiri zamafakitale. Amagwiritsidwa ntchito ngati binder, emulsifier ndi stabilizer muzinthu zosiyanasiyana, kuphatikizapo zakudya, mankhwala, zodzoladzola ndi zosamalira munthu. Amagwiritsidwanso ntchito ngati thickening wothandizira mu zomatira, zokutira ndi sealants.

Ponseponse, HPMC ndi chisankho chabwino kwambiri ngati chowonjezera pakhoma putty powder. Imapereka maubwino angapo kuphatikiza kuwongolera bwino, kusunga madzi, kumamatira komanso kuyanjana ndi zina zowonjezera.
