2. Epoxy moisture control system - Wikipedia

   en.wikipedia.org/wiki/Epoxy_moisture_control_system

   Epoxy moisture control systems are chemical barriers that are used to prevent moisture damage to flooring. Excessive moisture vapor emissions in concrete slabs can mean significant, expensive damage to a flooring installation. Hundreds of millions of dollars are spent annually just in the United States to correct moisture-related problems in ...

3. 4,4'-Diaminodicyclohexylmethane - Wikipedia

   en.wikipedia.org/wiki/4,4...

   In the epoxy industry it is often referred to as PACM, short for para-diamino­dicyclohexyl­methane. It is used as a curing agent for epoxy resins [1] It finds particular use in epoxy flooring. [2] Another use is to produce diisocyanates, which are precursors to polyurethanes. The mixture is a colorless solid, but typical samples are yellowish ...

4. Floor slip resistance testing - Wikipedia

   en.wikipedia.org/wiki/Floor_slip_resistance_testing

   Pendulum floor slip resistance tester. The ASTM E303-22 [1] (United States), BS EN 16165:2021, [2] BS EN 13036-4:2011 [3] (United Kingdom and many other European nations), AS 4663:2013 - Slip resistance of existing pedestrian surfaces, and AS 4586:2013 - Slip resistance classification of new pedestrian surface materials (Australia/New Zealand) slip resistance test standards define the pendulum ...

5. FR-4 - Wikipedia

   en.wikipedia.org/wiki/FR-4

   FR-4 epoxy resin systems typically employ bromine, a halogen, to facilitate flame-resistant properties in FR-4 glass epoxy laminates. Some applications where thermal destruction of the material is a desirable trait [ citation needed ] will still use G-10 non flame resistant .

6. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.

7. Epoxy value - Wikipedia

   en.wikipedia.org/wiki/Epoxy_value

   The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53).
