Milliput
Milliput is a brand name for a two-part epoxy putty used extensively in modeling, sculpting, repair work, and various crafting applications. It consists of two separate sticks, generally sold together in a package. Each stick contains a different component: one is typically a resin, and the other a hardener (also known as a catalyst or activator).
To use Milliput, equal quantities of the two parts are thoroughly mixed together by hand. The mixing process initiates a chemical reaction, causing the putty to gradually harden. The working time, or the amount of time the user has to manipulate the putty before it becomes too stiff, varies depending on the specific type of Milliput and the ambient temperature, but it is typically in the range of several hours.
Once fully cured, Milliput becomes a hard, durable, and waterproof material. It can be sanded, filed, drilled, and painted, making it suitable for a wide range of applications where a strong and versatile filler or sculpting medium is required. Milliput is available in various grades, each with slightly different properties such as color, working time, and fineness. Common grades include Standard (Yellow-Grey), Superfine White, Terracotta, Silver Grey, and Black. These grades cater to different aesthetic and functional requirements.
Milliput is prized for its ability to bond to a wide variety of materials, including metal, plastic, wood, glass, and ceramics. This versatility makes it a popular choice for repairing damaged items, filling gaps, and creating custom parts or details. Its waterproof nature also makes it suitable for use in marine environments or for projects that will be exposed to moisture. The cured material is generally considered to be non-toxic, but it is advisable to wear gloves during mixing and application to avoid skin irritation.
