1. Utomoni wa polima: womwe uli pakatikati pa tinthu tating'ono ta mphira, ndiyenso gawo lalikulu la ufa wa latex wopangidwanso, mwachitsanzo, polyvinyl acetate/vinyl resin.

2. Zowonjezera (zamkati): Pamodzi ndi utomoni, amatha kusintha utomoni, monga mapulasitiki omwe amachepetsa kutentha kwa mafilimu a resin (kawirikawiri vinyl acetate / ethylene copolymer resins safunikira kuwonjezera plasticizers) Osati mtundu uliwonse wa Rubber ufa uli ndi zowonjezera zowonjezera.

3. Kuteteza colloid: wosanjikiza wa zinthu hydrophilic wokutidwa padziko redispersible latex ufa particles, ambiri a zoteteza colloid wa redispersible latex ufa ndi polyvinyl mowa.

4. Zowonjezera (zakunja): Zida zowonjezera zimawonjezeredwa kuti zipititse patsogolo ntchito ya redispersible latex powder.Mwachitsanzo, kuwonjezera ma superplasticizers ku ufa wina wa rabara wothandizira kutuluka, monga zowonjezera mkati, si ufa uliwonse wa latex womwe uli ndi zowonjezera zotere.

5. Anti-caking agent: fine mineral filler, yomwe imagwiritsidwa ntchito kwambiri poletsa kuyika kwa ufa wa rabara panthawi yosungira ndi kuyendetsa ndikuthandizira kutuluka kwa ufa wa rabara (wotayidwa m'matumba a mapepala kapena matanki).
