AeroMarine Products’ liquid latex is one of the strongest and thickest latex rubber products on the market. This natural liquid latex features a solids content between 68 and 70 percent to minimize shrinkage while allowing the latex to pick up a model’s fine detail. Our liquid latex for molds feature high stability and good tear resistance, making them an integral component in a variety of mold-making applications.

Liquid Latex for Molding from AeroMarine Products, Inc.

Liquid latex rubber is a smooth-flowing liquid latex that can be easily applied over models to produce plaster castings and molds. Liquid latex molds are created through the application of a series of single coatings of liquid latex. Pure liquid latex rubber is brushed on models to form one-piece molds, allowing you to use models made of ceramic, clay, plaster, or wood without harming the model itself.

What makes AeroMarine Products’ liquid latex for molds different than other products on the market?

Our liquid latex for molds is designed to be applied thicker than any other liquid latex, providing easier application and an improved end result—making it the ideal mold builder. This liquid latex is eco-friendly, crafted from reclaimed rubber tires. We’ve crafted our liquid latex for molding with a medium solids content, which minimizes shrinkage while still allowing your model’s finer details to shine through. Like our RTV mold-making silicone, AeroMarine Products’ liquid latex rubber is relatively quick drying.

What’s the shelf life of AeroMarine Products’ liquid latex?

Our liquid latex for molding has a shelf life of around six months, so long as it is stored in a cool place, ideally between 60 and 72 degrees Fahrenheit. Stir the liquid latex after it has been stored or shipped to ensure your resulting mold is stretchable and flexible.

Pro Tip: Liquid latex that develops a putrid odor or takes on the consistency of cottage cheese has been spoiled.

How to Apply AeroMarine Products’ Liquid Latex:

  1. Start from the bottom of the model and brush on liquid latex in a thin, even coat
  2. After you’ve reached the bottom, continue out from the base to create a 2-inch flange
  3. Allow each coat to air-dry completely before you apply the next coat
  4. Apply the liquid latex in alternating directions to minimize shrinkage

How do I use black rubber powder?

If you’d like to extend and thicken your liquid latex, thereby reducing the number of coats needed, begin by applying four coats of plain liquid latex to your model. After this has dried, mix black rubber powder into your liquid latex in a 1:1 ratio.
