Surface Preparation	All surfaces to be coated should be clean, dry and free from contamination.   Abrasive Blast Cleaning Abrasive blast clean to Sa2½(GB/T 8923.1-2011). If oxidation has occurred between blasting and application of 725-H06-30, the surface should be reblasted to the specified visual standard.   Surface defects revealed by the blast cleaning process should be ground. Filled, or treated in the appropriate manner.   Shop Primed Steelwork   Weld seams and damaged areas should be blast cleaned to Sa2½(GB/T 8923.1-2011).   If the shop primer shows extensive or wildly scattered breakdown overall sweepblasting may be necessary.   Repair The areas to be repaired should be cleaned to St3(GB/T 8923.1-2011)by  mechanical method or higher level of surface prepared to Sa2.5(GB/T 8923.1-2011)by abrasive blasting. Abrade the area immediately surrounding the repair to provide a key for subsequent coating application. Overlap areas should be kept to a minimum.
Limitations	This product will not cure adequately below 5?. For maximum performance ambient curing temperature should be above 10??   Apply in good weather. Temperature of the surface to be coated must be least 3?above the dew point when the humidity is lower than 85%.   Before overcoating 725-H06-30, it must be clean, dry and free of zinc salts.   725-H06-30 Part A may cause some gas when the component was storage at high temperatures. Care should be taken when opening containers. 725-H06-30 will react with acid or alkali solutions.   The dry time and overcoating interval may change according to the environment factors.   Avoiding absorb the solvent steam and paint steam for long time. Skin and eyes must avoid contacting the paint. Pay attention to ventilate and fireproof when applying.
