Lens black edge of reason 
 Silver layer (aluminum layer) in the mirror in the electrolyte (acid, alkali, salt, etc.) the role of oxidation while black. 

 The corrosive effects of common substances on the mirror 
 An air trace of acid gases (carbon dioxide, sulfur dioxide) 
 2, concrete (Concrete Alkali role of water-soluble salts) 
 3, daily chemical products (including surfactants, metal ions, the system is generally alkaline or acidic) 
 4, the human sweat (salt) 
 5, the construction site or other decoration materials brought about by a variety of pollutants, such as: silicone rubber (plastic glass) 
 Clean water, moist air. 

 The solution of the lens black border 
 Zhongshan Tom's Glass Co., Ltd. R & D Edge glue, completely solve the problem of the black border. Its mechanism of action: 
 Edge glue and silver to form complexes, silver passivation passivation layer, harder to oxidative corrosion 
 2, form a dense protective film on the surface, to prevent the penetration of various types of electrolytes, cut off the contact of the electrolyte and the silver layer (aluminum layer) to protect the mirrors from corrosion, and greatly extend the life of the mirror. 

 Instructions for use 
 Do not have to shake before use. 
 Clean mirror edging. 
 (Mirror edging Edge glue as soon as possible, get a better protective effect). 
 Inverted bottle, the bottle a little squeeze hard and repeatedly pressed the sponge head, until the sponge full of glue. 
 The glue coating on the mirror side of the coating to keep the sponge filled with glue. 
 The best use of temperature above 5 ℃. 
 Cap tightly after use, the environment, above 0 ° C to prevent frost.
