C-UV 5181 Technical Data Sheet
UV/Visible light cure 紫外/可见光固化
encapsulating Adhesive 密封胶粘剂
PRODUCT DESCRIPTION 产品介绍
C-UV 5181 is a one component, UV curable encapsulating adhesive. The material cures fast when exposed to 365 nm light. The cured film displays good humidity resistance, excellent high temperature and thermal shock stability, solvent resistance, good toughness. The application include sealant, coating and encapsulation of electronic devices to circuit boards and semiconductors (transistors, watch IC, etc.) it is a UV curing sealant system to save energy and time for high speed production。C-UV 5181是一种单组分，UV固化密封胶粘剂。该产品可在365 nm紫外光辐照下快速固化。固化后的材料膜层具有优良的耐潮性能，卓越的高温和热冲击稳定性，不溶解性和高粘接性。它可用于电子元器件到电路板及半导体（晶体管，集成电路）的密封，途覆和封装。C-UV 5181是一种用于高速生产上节省能量消耗和时间的UV固化密封材料。

CURING TIME TABLE 固化进度表
The material cures when exposed to ultraviolet radiation and/or visible light with sufficient intensity. Recommended intensity for cure is 40 mW/ cm2 at 365 nm with exposure time of 4 – 5 times the fixture time at the same intensity. For dry curing of exposed surfaces, higher intensity UV is required, e.g. 100 mW/ cm2 minimum. 在足够强度的紫外和（或）可见光辐照下该产品可固化。推荐固化光强度为40mW/ cm2 at 365 nm，所需时间为相同光强下初固时间的4-5倍。对于外露表面的干养护，推荐使用更高强度的紫外光，如至少100 mW/ cm2。
STORAGE INFORMATION 储存方法
