Shijiazhuang lead-acid batteries sealants, battery shell plastic cover, red and blue plastic battery Baoding ..

Battery special sealant (shell plastic cover) a. Introduction epoxy housing cover is room temperature curing epoxy adhesive material, widely used in acid resistance and adhesion strength and sealing performance requirements of battery casing cover adhesive seal. The main components epoxy glue the cover electronic grade low-viscosity epoxy resin, curing agent and additives to strictly refining process, the main features are as follows: 1. Layer flat, bright, little shrinkage. Moderate room temperature can be of use, fast curing, medium viscosity, easy to operate. 2. The cured product of the mechanical and electrical properties of stable, long-term strong acid environment, does not affect the binding strength and appearance. II.
