1. Förfarande för framställning av formstycken genom varm-pressning av organiskt och/eller oorganiskt material, blandat eller mättat med en förening som används som bindemedel och som innehäl-ler NCO-grupper, varvid man dessutom använder ett medel för lösgö-rande av formstycket frän pressformens yta, känneteck- n a t därav, att som bindemedel används efter varmpressningen ett väsentligen vattenfritt polyisocyanatbaserat bindemedel, som har självlösgörande inverkan pa formstycket frän pressformens yta, och som innehäller A) ett polyisocyanat, som är 2,4- eller 2,6-toluylendiiso-cyanat eller en blandning av isomerer av dessa, ett polyfenylpoly-metylenpolyisocyanat, som framställs medelst anilinformaldehydkon-densation och därtill hörande fosgenering, eller ett polyisocyanat, modifierat med karbodimid-, uretan-, allofanat-, isocyanurat-, urea- eller biuretgrupper, och som härleds ur 2,4- och/eller 2,6-toluylendiisocyanat eller 4,4'- och/eller 2,4'-difenylmetandiiso-cyanat, och B) en praktiskt tagen vattenfri sulfonsyra med den allmänna formeln (I) r-(- S03H)n (I) väri n är heltalet 1 eller 2 och R är en aromatisk kolvätegrupp med 6-14 kolatomer, en ali-fatisk kolvätegrupp med 10-18 kolatomer, en cykloalifatisk kolvätegrupp med 6-15 kolatomer, en aralifatisk kolvätegrupp med 7-15 kolatomer eller en alkaromatisk kolvätegrupp med 7-24 kolatomer, varvid ekvivalentförhällandet för beständsdelarna A) och B) är 100:0,5 - 100:20.
2. Förfarande enligt patentkravet 1, känneteck- n a t därav, att beständsdelen B) är en sulfonsyra med den allmänna formeln (I), väri R är en alkylsubstituerad fenylgrupp med to-talt 9-20 kolatomer och n är 1.
3. Förfarande enligt patentkravet 1 eller 2, känne- t e c k n a t därav, att bindemedlets beständsdel A) är en fos-
