Why Cosplay Props Need the Right Silicone

Mold Tears Around Undercuts

Choose softer, higher-tear silicone for horns, claws and complex shapes.

Silicone Sags on Vertical Surfaces

Use brush-on silicone or thixotropic adjustment for helmets and masks.

Difficult Demolding

Avoid silicone that is too hard for detailed resin props.

Mold Deforms on Large Parts

Use medium-hardness silicone and a support shell for helmets and armor.
