| POLY[(O-CRESYL GLYCIDYL ETHER)-CO-FORMALDEHYDE] Usage And Synthesis |
| Chemical Properties | Hazardous polymerization can occur with aliphatic
amines in quantities greater than 1 lb. | | Uses | The epoxy novolac resins are
used and cured in ways similar to the resins based on the
diglycidyl ether of bisphenol A. These resins differ from
bisphenol A epoxy resins in that whereas a bisphenol A
polymeric chain can contain a maximum of two epoxide
group regardless of chain length, cresolic and phenolic
novolacs can contain an epoxide group for each phenol or
cresol molecule incorporated in the chain.
Because of their high functionality, epoxy novolac resins,
when cured, produce tightly cross-linked systems with improved high-temperature performance, chemical resistance,
and adhesion over the resins based on the diglycidyl
ether of bisphenol A. The thermal stability of epoxy novolac
resins has made them useful for structural and electrical
laminates and as coatings and castings for elevated temperature
service. Owing to the chemical resistance of these resins,
they are used for lining storage tanks, pumps, and other
process equipment as well as for corrosion-resistant coatings. | | Uses | For high temperature adhesives, coatings, electrical and laminating products. | | Production Methods | The term novolac refers to the reaction products of phenolic
compounds and formaldehyde. Glycidation of the phenolic
hydroxyl groups by epichlorohydrin under conditions similar
to those used for forming the diglycidyl ether of bisphenol A
produces the corresponding epoxy novolac resins. The average
n in the above formula varies from 0.2 to 1.8, depending
on the ultimate use of the resin. |
