rmationandfurthertechnicalsupport.光变材料光变材料是随着紫外线强度的变化而产生颜色变化
的材料。光变原理:具有光变功能的化合物在一定的波长和强度的光源激发下,其分子结构会发生可逆变化,直观表现为颜色发生变化,当停止激发
后,化合物会恢复至初始状态,直观表现为颜色消退至初始状态。产品变色描述:常规产品为无色变有色,可根据客户需求,定制有色变有色产品。
光变产品分类:光变粉、光变染料、光变乳液(三个链接块)光变粉产品说明:光变粉的平均粒径为3±1μm,是使用微胶囊技术加工制备的光
变材料,使用简单,适用性广,可用于油墨、涂料、注塑等多个领域。建议用途及用量:用于油墨及涂料:2~20wt%用于注塑:0.2~2
wt%产品特性:光变粉的环境耐受性和抗光老化性能高,使用简便,但不适用于对透光度有较高要求的领域,如眼镜片、透明膜类产品。色卡:
注意事项:若有高温工序,建议加工温度不高于220度,加工时间不超过30min。添加热稳定剂、降低加工温度或缩短高温加工时间均有助
于提升最终产品的变色性能。建议客户使用前先进行小试,若需要进一步技术支持,请联系我们。DYpowderProductIntro

technicalsupport.光变染料产品说明:光变染料需溶解在合适介质(如油性溶剂、树脂)中才能产生光变现象。介质的极性
对光变染料的变色性能有较大影响,建议使用前先打样确认显色状态。建议用途及用量:用于油性油墨及涂料:0.3~3.0wt%用于制膜:
0.2~1wt%用于注塑:0.1~0.8wt%产品特性:光变染料为有机化合物,可溶解在有机体系中,从而实现体系完全透光。注意事
项:光变染料极易受环境中光线、氧气、pH值等因素影响,产生光老化现象,直观表现为使用寿命缩短甚至丧失光致变色能力。建议在使用过程中
添加抗氧剂和紫外吸收剂来提高光变染料的抗光老化性能。值得注意的是,不同的使用介质所适用的助剂种类和用量会有较大差异,错误的使用助剂
可能会加剧光老化现象。光变染料的分解温度较低,若有高温工序,建议加工温度不高于220度,加工时间不超过30min。降低加工温度或
缩短高温加工时间均有助于提升最终产品的变色性能。建议客户使用前先进行小试,若有进一步技术支持需要,请联系我们。PMemulsio
