Shopping for some polyurethane

Polyurethane from Peenya

100 gm PU + 25 gm hardener

Pot life 25 minutes

Room temperature polymerization

Hardener ( 350/kg)+ 2kg Pu 610 – 375 Rs

We also bought a kg of PU 242 which more flowing. However this had a lot of airbubbles and the Casts were rubbery not plastic type stiff
