2. Release agent - Wikipedia

   en.wikipedia.org/wiki/Release_agent

   The matrix is created by the other ingredients in the semi-permanent mold release. Applications of semi-permanent mold release vary from every cycle to once daily applications depending on the compound being molded and the design and quality of the mold. Silicone-based rubber products, however, require a non-silicone based releasing agent.

3. Plastic cement - Wikipedia

   en.wikipedia.org/wiki/Plastic_cement

   Plastic Cement may refer to: Cement, in the US where it refers to certain formulations of Masonry Cement; Dichloromethane, used to solvent weld some thermoplastics including acrylic; Butanone, model cement is a thick mixture with polystyrene; Tetrahydrofuran, the main solvent in PVC cement

4. Solvent bonding - Wikipedia

   en.wikipedia.org/wiki/Solvent_bonding

   Solvent bonding differs from adhesive bonding, because the solvent does not become a permanent addition to the joined substrate. [4] Solvent bonding differs from other plastic welding processes in that heating energy is generated by the chemical reaction between the solvent and thermoplastic, and cooling occurs during evaporation of the solvent ...

5. Conservation and restoration of ceramic objects - Wikipedia

   en.wikipedia.org/wiki/Conservation_and...

   Cement mortar can be chiselled away with a hammer and chisel gradually. Plaster is easily removed through mechanical methods such as chiselling and chipping away with sharp implements. Saws, drills, and other mechanical methods can be used to remove the bulk of protruding materials; however, scratches, chips, and breaks can occur. [4]: p.77–78

6. Poly(methyl methacrylate) - Wikipedia

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

   It is supplied as a powder with liquid methyl methacrylate (MMA). Although PMMA is biologically compatible, MMA is considered to be an irritant and a possible carcinogen. PMMA has also been linked to cardiopulmonary events in the operating room due to hypotension. [42] Bone cement acts like a grout and not so much like a glue in arthroplasty ...

7. Sodium silicate - Wikipedia

   en.wikipedia.org/wiki/Sodium_silicate

   The largest application of sodium silicate solutions is a cement for producing cardboard. [1] When used as a paper cement, the sodium silicate joint tends to crack within a few years, at which point it no longer holds the paper surfaces cemented together.

8. Zinc stearate - Wikipedia

   en.wikipedia.org/wiki/Zinc_stearate

   It is widely used as a release agent for the production of many kinds of objects: rubber, polyurethane, polyester processing system, powder metallurgy. These applications exploit its "non-stick" properties. [3] In cosmetics, zinc stearate is a lubricant and thickening agent used to improve texture. [4]

9. 2-Acrylamido-2-methylpropane sulfonic acid - Wikipedia

   en.wikipedia.org/wiki/2-Acrylamido-2-methyl...

   AMPS is made by the Ritter reaction of acrylonitrile and isobutylene in the presence of sulfuric acid and water. [2] The recent patent literature [3] describes batch and continuous processes that produce AMPS in high purity (to 99.7%) and improved yield (up to 89%, based on isobutene) with the addition of liquid isobutene to an acrylonitrile / sulfuric acid / phosphoric acid mixture at 40°C.
