用外涂層時,由于空氣的存在,會抑制樹脂的固化,導(dǎo)致表面會發(fā)粘或固化不完全,此時必須加入樹脂0.2-0.4%的石蠟,加入時最好先配制成10%的苯乙烯石蠟溶液。但含蠟樹脂只能用于表層,否則會降低層間的結(jié)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.)
