The surface cleaning work of the substrate, the surface cleaning of the adhesive material plays a decisive role in the quality of the project, therefore, strict surface cleaning is the key to improve the quality of the project.

The purpose of surface treatment before bonding of Auman 955 structure is to remove oil, dust, surface damage and loose natural oxide film from the surface of the substrate during production and transportation, so as to coarse the surface of the substrate, form the surface form suitable for the mechanism embedding, improve the surface chemical properties, and improve the durability under the influence of stress environmental factors.

      If the surface is improperly treated and not cleaned before the use of 955 structural adhesive, sealant and any matrix can not maintain a long-term bond. Therefore, the use of the correct cleaning agent and compliance with the specified surface treatment and cleaning procedures are the prerequisite for good bonding effect.

      Base coating application, according to the compatibility and adhesion test results to choose the base coating to use, the base coating should be used after cleaning agent cleaning, pour enough to immediately use the bottom coating in a small container (not more than 10 minutes of dosage), will be equipped with the remaining bottom coating container cover tightly, in order to prevent solvent volatilization or water absorption and deterioration.

      During the construction of the renovation and repair project, it may be necessary to repair or re-assemble during the construction process and after the completion of the construction, such as: the repair of the glue cutting test unit, the damage of the glass surface caused by various circumstances, the failure of the curtain wall system such as the failure of adhesion or water leakage.

      The curing time of 955 structural adhesive is increased with the increase of bonding thickness. For example, 12mm thickness of acid silicone sealant may take 3-4 days to set, but within about **, the outer layer of 3mm has been cured. General 955 structural adhesive contains plasticizer and other non-reactive low molecular substances, which will migrate from the inside of the adhesive to the inside of the stone, and oil and dust will appear on the stone surface, causing stone pollution. There are two types of glue.

      One is the stone sealant, used for the sealant sealing between stone plates. After gluing must be air drying, air drying purpose is to let the solvent volatilize clean, increase viscosity, promote curing, do not immediately overlap, so as to avoid adhesive layer sticky or produce bubbles, resulting in a decline in bond quality. Airing time for 20-25 minutes in winter, 5-15 minutes in summer, when the adhesive layer is dry film adhesive immediately, airing time should not be too long, so as to avoid the adhesive layer lose viscosity, affect the bond strength.
