Holden's Mold Making Latex

Holden's Mold Making Latex provides several options tailored to different molding needs:

HX-80™: A low viscosity latex suitable for flat molds, offering low shrinkage and high wear resistance. Ideal for plaster, concrete, and wax applications. Not recommended for high-exotherm resins.
High Viscosity HX-974™: Designed for detailed glove molds, this brushable latex requires 10-20 layers for durability. Suitable for plaster, concrete, and wax casting. Avoid using with high-exotherm resins.
Coating/Dipping Latex HX-200™: Pre-vulcanized and low viscosity, this latex is perfect for creating thin, stretchy skins, often referred to as "balloon" latex. Use with FabTone™ pigments for color customization.
Frisket Mask Latex: A removable liquid latex masking fluid for surfaces like paper, glass, and metal. Non-staining and compatible with water-based mediums, but not recommended for fabrics.
