用外涂層時(shí)，由于空氣的存在，會(huì)抑制樹(shù)脂的固化，導(dǎo)致表面會(huì)發(fā)粘或固化不完全，此時(shí)必須加入樹(shù)脂0.2-0.4%的石蠟，加入時(shí)最好先配制成10%的苯乙烯石蠟溶液。但含蠟樹(shù)脂只能用于表層，否則會(huì)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.)
