How To Choose a Self-Adhesive Glue
01 permanent and can remove sexual choice In terms of the performance of binders, it is generally divided into two categories: permanent adhesives and removable adhesives. Permanent commonly used in electronic, mechanical, do not need to remove out. Removable is generally used for food or everyday items, such as fruit labels, clothing labels, etc. 02 The difference between objects to be affixed Self-adhesive labels may be attached to the surface of different materials, such as glass, metal, plate making and plastic. The surface texture of different materials is not used, so the selection should take into account the material to be affixed. If the surface material is rough, it needs a strong viscosity glue. 03 Influence of the surface shape of the attached object The surface of the object to be affixed has a plane and a curved surface. If it is curved, it may need a glue with good adhesion or strong viscosity, and a material with better softness and tensile resistance should be selected. The flat surface of the attached object ADAPTS to a wider range of label materials. 04 posted surfaces clean condition Self-adhesive material is most suitable for surface clean, dry, no oil and dust label base material. In any case, it is necessary to keep the surface of the paste dry and clean in order to achieve the best labeling effect. 05 Impact of environment on self-adhesive labels The labeling environment needs appropriate temperature and humidity to ensure the labeling effect. The use of the environment will also affect the choice of glue, extremely cold or high temperature special use of the environment for glue requirements are also different. Adhesive Advantage Disadvantage Applications Hot melt adhesive It belongs to rubber base adhesive. Strong fluidity, strong viscosity, suitable for low temperature use,non-toxic environmental protection. It is not resistant to high temperature, the processing process is sensitive to temperature, and it becomes hard and brittle when stored below -15℃. Poor reattachment, can not be attached to PVC material. Do not need too high temperature labeling environment, can be attached to food, medicine or supermarket labels. Water-based adhesive Belongs to the acrylic adhesive, strong viscosity, the vast majority of environmental protection non-toxic, relatively high temperature resistance. Below 90℃, a few below 150℃. Low temperature body surface performance is poor, the paste should be dry and clean, water-based glue fluidity is poor. It is used in food, medicine, daily chemical products, or industrial labels with strict environmental protection requirements. Solvent adhesive It is a kind of adhesive which is dissolved and coated with solvent as medium. It has strong viscosity, is not easy to overflow, is resistant to high temperature, and can be adapted to outdoor labeling. Not environmentally friendly, most are toxic, and the price is high. It is used for electronic labels and some labels for high-temperature environment ...
