Environmental degradation aspects influencing  coach-working one-component epoxy adhesives

Toughening Epoxy Adhesives to Meet Today’s Challenges

There are many advantages that polymeric adhesives can offer compared to the more traditional methods of joining such as bolting, brazing, welding, mechanical fasteners, etc. and epoxy adhesives represent the most common type of structural adhesive. When polymerised, epoxy adhesives are amorphous and highly-crosslinked materials and this microstructure results in many useful properties for stru...

Occupational dermatitis from a one-component naphthalene type epoxy adhesive.

In an electronics plant, a new one-component naphthalene type epoxy resin was used as an adhesive for reinforcing a circuit board. The resinous part of the adhesive consisted of diglycidyl ether of bisphenol A (DGEBA) and 1,6-bis(2,3-epoxypropoxy)naphthalene type epoxy resins. The hardener was methylhexahydrophthalic anhydride (MHHPA). Of 54 workers, 15 (27.8%) were diagnosed to have work-relat...

Degradation analysis of lignocellulosic fillers infused coir epoxy composites in different environmental conditions

India has large resources of natural fibres such as Banana, Khus, Sisal, Korai grass,Talipot, Palm leaf, Coconut, Pineapple, Screwpine, Golden grass, Jute and Sabaiamong others. In the past, trade of the village folk depended on harvesting fibresgrown in their villages. Natural fibers have recently gaining attraction of researchersdue to their low cost eco-friendly and biodegradability characte...

Skin Damage Due to Acrylic or Epoxy Adhesives

Epoxy functionalized multi-walled carbon nanotubes for improved adhesives

Three different types of epoxy-functionalized multi-walled carbon nanotubes (EpCNTs) were prepared by multiple covalent functionalization methods. The EpCNTs were characterized by thermogravimetric analysis (TGA), infrared spectroscopy (FTIR), and Raman spectroscopy to confirm covalent functionalization. The effect of the different chemistries on the adhesive properties was compared to a neat c...
