Niin sanottu \"synergiavaikutus\" viittaa t\u00e4rkkelysaetterin ja muiden kipsilaastij\u00e4rjestelm\u00e4n komponenttien (erityisesti proteiinipohjaisten hidastimien) v\u00e4liseen vuorovaikutukseen, joka tuottaa parempia tuloksia kuin niiden yksitt\u00e4isten vaikutusten summa.<\/p>

Synergia hidastimien kanssa:<\/b><\/strong>\u00a0Kipsi kovettuu nopeasti, ja usein tarvitaan proteiinipohjaisia hidasteita ty\u00f6st\u00f6ajan pident\u00e4miseksi.

Yhdistettyn\u00e4 t\u00e4rkkelys eetteri kuitenkin auttaa dispergoimaan ja stabiloimaan hidastimen tasaisemmin j\u00e4rjestelm\u00e4ss\u00e4. Tuloksena on laasti, jonka ty\u00f6stett\u00e4vyys on hyv\u00e4, jonka avoin aika on paremmin hallittavissa ja jonka lujuudenkehitys my\u00f6hemm\u00e4ss\u00e4 vaiheessa on vakaampi.<\/p>

Synergia kipsihiukkasten kanssa:<\/b><\/strong>\u00a0T\u00e4rkkelyseetterin pitk\u00e4ketjuiset molekyylit voivat adsorboitua kipsihiukkasten pinnalle muodostaen vakaan kolmiulotteisen verkkorakenteen.

Yhteenvetona voidaan todeta, ett\u00e4 t\u00e4rkkelys on kaikkea muuta kuin pelkk\u00e4 sakeuttamisaine.
