  • UV-Cure Adhesives 101
    weighed and mixed prior to use. After these adhesives are applied, it takes heat to drive off solvents and other volatiles and speed the cure or hardening, especially for two-component mixtures. This thermal curing puts as many as 6 gallons of solvent into the air for every gallon of solid adhesive...
  • Polymer Castings take on metals
    and additives can nearly eliminate it. Epoxy makes sense when precision and high strength are key design considerations. A downside of epoxy is that it takes several hours to cure. Polyester, in contrast, has a high shrink rate and is therefore inappropriate for high-precision parts. It's also...
  • Down-to-earth role for imidized polymers
    the polymer's high heat, chemical, or flame resistance. Traditionally, the first group of imidized polymers, PIs, were thermoset polymers that couldn't be melt processed because of their highly branched or crosslinked molecular structure. Crosslinking boosts the polymer's heat and chemical resistance...
  • What Happens When You Heat A Label? (.pdf)
    further, with the similar effect of enhanced. physical and chemical resistance. And the adhesive may "thermoset", as the heat. causes it to cure into a hard, chemically impervious, highly cross-linked plastic. Yet, some inks, coatings, and adhesives may only undergo slight chemical. reactions...
  • Predicting plastic part life
    Dynamic mechanical analysis helps designers build longer lasting products. Edited by Jean M. Hoffman DMA testing helps determine the effect of different curing conditions on thermoset polyester products. DMA demonstrates the degree of cure based on the stiffness and glass transition temperature...
  • Seven Versatile Sealing Materials
    activators work with accelerators to reduce vulcanization or cure time and improve a compound's final characteristics. Age resistors such as antioxidants and antiozonants slow the deterioration of rubber products due to exposure to light, heat, oxygen, radiation, and ozone. Fillers can reduce costs...
  • Keeping contaminants out
    -site monomer that reacts to radicals, such as a brominated or iodinated monomer. In general, bisphenol-AF cure systems have better heat resistance than peroxide systems; however peroxide cure systems can have better chemical resistance. Compounding ingredients such as carbon black and mineral fillers can...
  • Oil-Resistant Rubbers
    of the polymer chain, the most desirable properties are obtained by crosslinking with the use of peroxides or by radiation. Sulfur donor cure systems are available that produce vulcanizates with only minor performance losses compared to that of peroxide cures. However, the free radical crosslinking...
  • Guidelines for Bonding Plastics
    wavelength and irradiance causes them to fixture rapidly and cure. Secondary cure mechanisms, such as heat or chemical activators, completely cure adhesives in shadowed areas. Because cured acrylic adhesives are thermoset plastics, they offer superior thermal, chemical, and environmental resistance...
  • Bonds that take a beating
    Today's structural adhesives can be stronger than the parts they join. Edited by Jean M. Hoffman The Italian manufacture of Drop surfboards bonds rubber substrates to the fiberglass/epoxy composite board tail using methacrylate adhesives. The adhesives cure quickly and give good longlasting...
