Abstract

The relations between the degree of cure (the value obtained by “formaldehyde isolation test”) and the curing conditions were studied on melamine-formaldehyde resin laminates.<BR>The rate equation for hardening of resin in C-stage was proposed and the apparent activation energy was ca. 20.5 kcal/mol.<BR>Further, the effect of catalyst on curing temperature and time was studied quantitatively.<BR>Main experimental equations were shown below.<BR>The notations are<BR>F: degree of cure (mg/100cm2)<BR>T, (Tc): curing temperature (°K), (when using catalyst)<BR>t, (tc): curing time (min), (when using catalyst)<BR>C: catalyst added in varnish (%) a, a′, a″, k1, k1′, k1″, k2, k2′, k2″, α, β, γ, δ, to: const.
