Okutwarira hamwe, obutagatsi bw’okukora firimu bw’obucupa bwa latex oburikugaruka kujanjaara buri ahaiguru ya 0°C, obwo ebintu bya EVA omu muringo gw’omutaano biine obutagatsi bw’okukora firimu oburikwetoroora 0–5°C. Omu bwire bw’obutiti oburi ahansi, okukora firimu tikurikubaasa kubaho (nari omutindo gwa firimu niguba mubi), ekirikuremesa okuhinduka n’okuhamira kw’omucuucu gwa polymer. Okwongyera ahari ekyo, omubaro gw’okusheesheka kwa cellulose ether nigukyendeera aha bwire bw’obutagatsi bukye, ekirikuteganisa okuhamira kw’omucuucu n’okukora. Nahabwekyo, okwombeka kushemerire kukorwa ahaiguru ya 5°C nkoku kirikubaasika kureeba ngu purojekiti yaaguma eri nungi.
Ekirikuhamya amaani ga kare n‘ekirungo ekirikubaasa kutunguura amaani ga kare g‘omucuucu hatariho kukwata munonga aha maani gaakyo ag‘enyima. Okurugirira aha miringo y’eby’obuhangwa, neebaganisibwamu emiringo y’ebihangirwe n’ebitari bihangirwe: ebihangirwe ebirikureetaho amaani g’okubanza harimu calcium formate, triethanolamine, triisopropanolamine, urea, n’ebindi; ebitari by’obuhangwa harimu ebiriisa bya sulfate, kloride, n’ebindi.

Noyetenga eky’okwongyeramu ekirikubaasa kutunguura eby’okurya n’okutunguura okutaho sementi? Calcium formate yaitu ey’obuyonjo bw’ahaiguru neereetaho byombi – nyiga aha kwiguraho eby’okugarukamu ebitebeekanisiibwe ahabw’eby’obushuubuzi bwawe.
