2. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   Liquid epoxy resins in their uncured state are mostly classed as irritant to the eyes and skin, as well as toxic to aquatic organisms. [8] Solid epoxy resins are generally safer than liquid epoxy resins, and many are classified non-hazardous materials. One particular risk associated with epoxy resins is sensitization.

3. Curing (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Curing_(chemistry)

   Cure monitoring is, for example, an essential component for the control of the manufacturing process of composite materials. The material, initially liquid, at the end of the process will be solid: viscosity is the most important property that changes during the process. Cure monitoring relies on monitoring various physical or chemical properties.

4. Waterborne resins - Wikipedia

   en.wikipedia.org/wiki/Waterborne_resins

   Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...

5. Thermosetting polymer - Wikipedia

   en.wikipedia.org/wiki/Thermosetting_polymer

   Left: individual linear polymer chains Right: Polymer chains which have been cross linked to give a rigid 3D thermoset polymer. In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (). [1]

6. J-B Weld - Wikipedia

   en.wikipedia.org/wiki/J-B_Weld

   While J-B Weld Original epoxy dries to a dark grey color, [10] J-B Weld's ClearWeld epoxy dries clear. [11] Although its bond is not quite as strong as the Original's (3900 psi vs. 5020 psi), [ 12 ] ClearWeld is often preferred when appearance is an important consideration.

7. Injection moulding - Wikipedia

   en.wikipedia.org/wiki/Injection_moulding

   Mild steel, aluminium, nickel or epoxy are suitable only for prototype or very short production runs. [1] Modern hard aluminium (7075 and 2024 alloys) with proper mould design, can easily make moulds capable of 100,000 or more part life with proper mould maintenance.
