      W61-09 High temperature resistant exhaust pipe coating

      Composition: It is composed of organic silicon resin, active antirust pigment, penetrating agent, curing agent, additives, etc.
      Performance: This product not only has high temperature resistant performance, but also has excellent weather resistant, corrosion resistant performance. After high temperature treatment, the paint film can make the organic silicon and silicate minerals connect together, so as to protect the base material. This product has improved the poor corrosion resistance ability of former organic silicone coatings under normal temperature, high temperature and washing alternate cooling and heating state.
      Application: The coating can be used in automobile, motorcycle, agricultural vehicle exhaust pipe, engine and diesel engine high-temperature parts.

      Construction method

      1、Base material processing The coated base material surface must carry out thorough removal of grease, scale, rust, old coating, and etc., using shot or sand blasting method, to reach Sweden derusting standard Sa2.5 grade and roughness of 30-70μm, manual derusting methods can also be adopted to reach Sweden derusting standard St3 grade and roughness of 30-70μm.
      2、Mixture (applicable for two-component paint)
      According to the weight ratio (the label on the product packaging shall prevail).
      When mixing, under the condition of stirring the main agent continuously, slowly pour in curing agent to make it fully ad evenly stirred.
      20 min after curing of the well mixed coating, filter with 60-80mesh screen, and pour into another container for spare use.
      The mixed coating is valid for 3 hours; please arrange the use according to the construction progress.
      3、Baking (applicable for one-component paint)

      Product name Baking temperature Holding time
      High temperature resistant exhaust pipe coating 220℃ 30min
      280℃ 20min

      4、Construction conditions
      Coating operation shall be performed as soon as possible after the substrate processing, generally not exceeding 8 hours. The substrate surface temperature and environmental temperature are generally no less than 10℃, the surface temperature shall be at least 3℃ higher than the dew point temperature, and the relative humidity of the air shall not exceed 85%.
      5、Coating method
      This coating can use brush coating, airless spraying and auxiliary air spraying method for construction.
      6、Dilution
      Generally the coating shall use the matching thinner to adjust viscosity and cleaning tools.
      7、Coating intervals
      One-component paint can carry out later coating after drying; two-component paint is suggested to have the coating time intervals as follows:

      Substrate temperature 5℃ 20℃ 30℃
      Shortest 48h 24h 12h
      Longest No limit
