As we all know, metal logo nickel stickers are made of stainless steel, nickel and aluminum and other metals as basic materials and are made of process technology. These processes generally include: etching, electroforming, electroplating, oil injection, etc. Today's article mainly introduces to you: What are the glues commonly used by metal sign manufacturers?
1. Hot melt adhesive
Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, and its chemical properties remain unchanged. Its five poisonous, tasteless and environmentally friendly chemical products. Hot melt adhesive for metal nickel stickers is generally used on leather goods such as mobile phone holsters, wallets, bags, etc., and is operated by a hot press.
2. Water glue
Water glue is mainly used for surface bonding. Good bonding strength, can be cured at room temperature or medium temperature, and has the characteristics of small curing shrinkage, yellowing resistance, colorless and transparent, etc. It is an environmentally friendly chemical. In metal nickel stickers, water glue is used more, because water glue can be directly attached to the product, and it does not need to be pasted to the product with a hot press like hot melt glue. Moreover, the viscosity of the water glue is relatively high, and the adhesion to the product is firm.
3. Adhesive
The adhesive is characterized by good thermal shock resistance, high bonding strength, good retention and strong UV resistance. In the metal nickel sticker industry, it is necessary to decide what kind of glue to use for the sticker according to the material of the customer's product. No specific kind of glue is the best, only the most suitable.
The glue used for metal sign stickers will affect the life of the stickers. If the glue is not selected properly, it will reduce the performance of the sticker. So, you need to know these basics before making metal signs for your products.
