Cure Type / Technology

|
| |
Your choices are...
|
|
|
| |
Thermosetting (Crosslinking/ Vulcanizing)
|
|
Thermoset plastics and thermoset resins are crosslinked polymeric resins cured using heat or heat and pressure. Cured thermoset resins generally have higher resistance to heat when compared to thermoplastics, but they cannot be melted down and reprocessed.
Thermoset adhesives are crosslinked polymeric resins cured using heat or heat and pressure. Cured thermoset resins do not melt and flow when heated, but they may soften. Phenolic, melamine and urea formaldehyde resins are thermosetting adhesives that offer strong bonds and good resistance to high temperatures. Vulcanization is a thermosetting reaction involving the use of heat and/or pressure in conjunction with a vulcanizing agent, resulting in greatly increased strength, stability and elasticity in rubber-like materials. RTV silicone rubbers are room temperature vulcanizing materials. The vulcanizing agent is a crosslinking compound or catalyst. Sulfur is the traditional vulcanizing agent used with natural rubber. Silicones use moisture, acetic acid and other compounds as curing agents.
|
| |
Room Temp. Cure / Vulcanizing
|
|
Polymer resin or compounds that either cure or vulcanize at room temperature. Vulcanization is a thermosetting reaction involving the use of heat and/or pressure in conjunction with a vulcanizing agent, resulting in greatly increased strength, stability and elasticity in rubber-like materials. The vulcanizing agent is a crosslinking compound or catalyst. Silicones use moisture, acetic acid and other compounds as curing or vulcanizing agents.
|
| |
UV / Radiation Cured (also EB, Light)
|
|
UV or radiation cured adhesives use ultraviolet light, visible light or electron bean irradiation to initiate curing, which allows a permanent bond without heating or excessive heat generation. One disadvantage of UV curing adhesives is the requirement that one substrate is UV transparent. Some UV resin systems employ a secondary curing mechanism to complete curing of adhesive regions shielded from the UV light. EB curable adhesives use electron beam radiation to cure or initiate curing. The electron beam can penetrate through material that is opaque to UV light.
|
| |
Single Component System
|
|
Single component adhesives or sealant systems consist of one resin that hardens by reaction with surface moisture, a surface applied activator-primer, or through the application of heat.
|
| |
Two Component System
|
|
Two or multi-component adhesive or sealant systems consist of two or more resins or a resin and a hardener, crosslinker, activator or catalyst that when combined react and cure into a polyermized compound or bond. Two component systems are mixed and then applied.

|
|
Phenolic and formaldehyde resins are thermosetting molding compounds and adhesives that offer strong bonds and good resistance to high temperatures. Phenolic or phenol formaldehyde, urea formaldehyde, furan and melamine resins fit into this category. Phenolic resin adhesives made from chemicals of the phenol group and formaldehyde are generally are the most durable. Phenolic resins are available in liquid, powder, and film form. Special phenolic resins are available that harden at moderate temperatures when mixed with suitable accelerators. Phenol-formaldehyde, resorcinol-formaldehyde, resol and novalac resins are types of phenolic resins. Urea resin adhesives are made from urea, formaldehyde and catalysts or hardeners. Urea formaldehyde resins can harden rapidly at moderate temperatures, but generally do not have the properties of phenolic resins. Melamine resins are made through a reaction of dicyandiamide with formaldehyde. Most of the resins in this group have excellent dielectric properties. Furan formaldehyde (FF) resins are made by the polymerization or poly-condensation of furfural, furfural alcohol, or other compounds containing a furan ring, or by the reaction of these furan compounds with other compounds (not over 50%). Fire-retardant furans are used in hand lay-up, spray-up and filament winding operations. Furans are commonly used in foundry binders, grinding wheels, refractories and other high temperature applications. Furan resins and chemicals are also used in fiberglass composites, hybrid resins combined with epoxy or phenolics, and in corrosion-resistant cements.
