Poly 74-45 cures at room temperature without noticeable contraction. The mixture is very comfortable and is made equally in volume.

It is not necessary to extract the air by vacuum hood and the resulting molds have a very high production.

Poly 74-45 works especially well with pigmented or colored concrete (concrete), in molds made with Poly 74-45 reproductions will have precise and uniform colors.

Gypsum and wax can usually be molded into polyurethane molds without any release agent, but most concrete mixtures and polyurethane resins require a suitable release agent (e.g. Pol-Ease ® 2300 Release Agent ).
