What Is in Zero Shrinkage Mold Resin?

Zero shrinkage mold resin typically contains a high level of filler materials, specifically low shrinkage additives. These additives are generally more cost-effective compared to solvent-based fillers.

The presence of fillers might lead to a higher viscosity, which can affect the resin’s ability to wet out and penetrate properly. Therefore, it is essential to stir the resin thoroughly and roll it out carefully before use.

Some may wonder if they can add inert fillers to the resin themselves to reduce shrinkage. While this is possible, it is crucial to consider the viscosity of the mold resin and how the added fillers might impact its performance.

In conclusion, the efforts put forth by manufacturers to achieve zero shrinkage results from extensive testing and comparisons. Simply adjusting the formulation on your own may not yield the same effectiveness.
