外涂层（Top Coating）：
用外涂层时，由于空气的存在，会抑制树脂的固化，导致表面会发粘或固化不完全，此时必须加入树脂0.2-0.4%的石蜡，加入时最好先配制成10%的苯乙烯石蜡溶液。但含蜡树脂只能用于表层，否则会降低层间的结合力。(Oxygen
in the air will inhibit the complete cure of exposed resin layer.
In order to reduce or eliminate this effect, 0.2-0.4% wax can be
added to the resin used in the topcoat layer, the small amount of
wax is incorporated readily into the system by preparing 10%
wax-styrene. This waxed resin should only be used in topcoat,
otherwise they will inhibit adhesion of laminate layer.)
