2. Izod impact strength test - Wikipedia

   en.wikipedia.org/wiki/Izod_impact_strength_test

   Scheme for the determination of Izod impact strength test results. Impact, by definition, is a large force applied for a very short time, resulting in a sudden transfer of momentum and energy, and its effect is different when the same amount of energy is transferred more gradually. Everyday engineering structures are subjected to it and may ...

3. Strength of glass - Wikipedia

   en.wikipedia.org/wiki/Strength_of_glass

   Imperfections of the glass, such as bubbles, and in particular surface flaws, such as scratches, have a great effect on the strength of glass and decrease it even more than for other brittle materials. [2] [1] The chemical composition of the glass also impacts its tensile strength. [3]

4. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   It has a density of 1.17–1.20 g/cm 3, [1] [16] which is approximately half that of glass, which is generally, depending on composition, 2.2–2.53 g/cm 3. [1] It also has good impact strength, higher than both glass and polystyrene, but significantly lower than polycarbonate and some engineered polymers.

5. Paint adhesion testing - Wikipedia

   en.wikipedia.org/wiki/Paint_adhesion_testing

   The cross-cut test is a method for determining the resistance of paints and coatings to separation from substrates by utilizing a tool to cut a right-angle lattice pattern into the coating, penetrating to the substrate. A quick pass/fail test can be accomplished through this method.

6. Cast acrylic - Wikipedia

   en.wikipedia.org/wiki/Cast_acrylic

   Up to 17 times the impact resistance of ordinary glass; Half the weight of glass and ideal for precision machining; Highly resistant to many different chemicals; Has certain properties making it an ideal material for use in a wide range of applications, including medical, life sciences and food/beverage testing. PMMA – PolyMethyl MethAcrylate.

7. Acrylic paint - Wikipedia

   en.wikipedia.org/wiki/Acrylic_paint

   Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion and plasticizers, silicone oils, defoamers, stabilizers, or metal soaps. [2] Most acrylic paints are water-based, but become water-resistant when dry.
