ZA 4 LT Silicone, Addition Cure, 4 ShA

ZA 4 LT is a two-component RTV silicone rubber, which is especially recommended for making parts of moulds.

Extremely soft. Therefore it is advantageous where the tool requires high elongation at break. You can build a mould with harder addition cure silicone combined with ZA 4 LT at the specific part with a large undercut.


Suitable for use with polyurethane resin, acrylic resin, epoxy resin and polyester resin, but does not adhere to plasters, coatings, or paints either.


Main Application Areas:

In addition to mould manufacturing, it has a significant ink-adhesion ability. That’s why it is widely used for tampon printing and labelling tools.

Excellent for screen printing. It has high dimensional stability and good mechanical strength.


It is also used to make artistic ceramic forms. This silicone resin can be successfully applied where the surface is very complicated, coupled with small holes. Due to its high fluidity and low viscosity, which is almost like water, it allows penetration into the smallest voids.
