Epoxy-based coating

Other. 2-Nitro-1-butanol is an excellent solvent for many polyamide resins, cellulose acetate butyrate, and ethylceUulose. It can be utilized in paint removers for epoxy-based coatings. 2-Hydroxymethyl-2-nitro-l,3-propanediol is usebil for control of odors in chemical toilets. Its slow release of formaldehyde ensures prolonged action to control odor, and there is no reodorant problem which sometimes is associated with the use of free formaldehyde. 2-Hydroxymethyl-2-nitro-l,3-propanediol solutions are effective preservative and embalming fluids. The slow Uberation of formaldehyde permits thorough penetration of the tissues before hardening.

Sensitization of aryliodonium and arylsulfonium salts having nonnucleophilic anions can greatly increase the quantum efficiency of photolysis. This results in the more rapid curing of epoxy based coatings. 

The influence of the chemical structure of substances in PMB molecules in the curing process of epoxy materials was investigated. Stress-strain properties were determined by traditional physical-mechanical methods. Glass transition temperature was estimated by the thermomechanical method. Chemical resistance of the epoxy based coating cured by PMBs was determined by change of their impact strength after exposition in an aggressive environment within 42 days.

It is the purpose of this review paper to examine the relatively newer uses of these elastomer types as resin modifiers within the broad range of epoxy-based coating systems. 

Thicker epoxy-based coatings, highly flexibllized with amine-reactive nitrile liquid polymer, have been described by Mendelsohn (50) in which the flexibilizing hardener is comprised of an admixture of ATBN, fatty polyamide and boron trifluoride/amine complex. This coating ages well at 100°C and has excellent toughness/ flex with good abrasion and vibration absorption properties. 

Although structural, electronic, and conductivity properties of polyaniline are well known, oxidative corrosion mechanisms are not completely understood. It is accepted that for corrosion to occur both oxygen and water must come into contact with the surface. Therefore any barrier material will limit corrosion to some degree. To date, aniline-based coatings have been shown to provide a level of protection beyond the simple barrier limit. In these studies, epoxy-based coatings are com-... 

Epoxy-based coatings are the preferred and dominant choices for cathodic electrodeposition of automotive primers, marine and industrial maintenance coatings, and metal container interior coatings. Use of epoxy flooring for institutions and industrial buildings has been growing at a steady rate as the industry becomes more aware of its benefits. 

There are primarily two types of chemistries for the coating materials. One is epoxy-based and the other is acrylic-based. In general, epoxy-based coatings provide superior corrosion resistance and are used in applications where high corrosion resistance is required. This chemistry, however, does not have good resistance to ultraviolet light, and is commonly used in primer applications where a topcoat will be subsequently applied, particularly if the coated object needs to withstand sunlight. 

Al-Turaif, H.A. Surface morphology and chemistry of epoxy-based coatings after exposure to ultraviolet radiation. Prog. Oig. Coat 76, 677-681 (2013)... 

Experimental work [118-125], especially that using photoelastic techniques, has established the presence of residual stresses in joints but the results have often not been quantitative. For the simpler case of polymeric films coated onto metallic substrates, photoelastic techniques and a method based upon the bimetallic strip principle have often been employed [126-131]. Using the latter method, Danneberg [130] showed that for a wide range of epoxy-based coatings on an aluminium substrate thermal contraction was a major cause of internal stress and that the stresses generated were of the order of 0.08...
