The quality requirements of resin are:
(1) Good heat resistance, good thermal decomposition temperature and low thermal weight loss.
(2) the fineness of powder resin should be high, generally 100 ~ 200 mesh, preferably more than 200 mesh, which is conducive to the uniformity of mixture dispersion, and can reduce the amount of resin in the formula.
(3) The content of free phenol is low, 1% ~ 3% is appropriate.
(4) Suitable curing speed 40s ~ 60s (150℃) and flow distance (120℃ 40 ~ 80mm).
