Macromolecule metallic putty

General Description

  WB-1, WB-2,WB-3 macromolecule metallic putty are developed by our institute. After its performance testing and customer use, it is obvious that its main technical criteria and performance has reached the high level compared with foreign same products, it has lots of advantages such as high mending speed, easy constru-ction , low cost and safe etc.


Field of application
  The WB-1 metallic putty is machineable which is suitable for repairing all kinds of parts of machines and equipment such as shaft, shaft sleeve, pump body, cylinder, valve etc. Its application temperature is below 150℃.
  The WB-2 metallic putty is corrosion-resisting and wearres-isting after solidified, but it’s suitable for repairing the tube plate of heater, tower, reaction kettle, enamel kettle reactor, the application temperature is below 150℃.
  The WB-3 metallic putty is suitable for repairing coppery equipment and parts.

Sample Preparation
  1. Surface treatment: the surface which need to be repaired is roughened, cleaned and dried. All the old paint, rust and millscale must be removed until its metal surface appears and the surface has reached cert-ain roughness(Sa 2.5), then use cleaning agent such as trichloroethane or acetone to make surface degrease.
  2. Mixing: WB-1, WB-2,WB-3 are bicomponent materials, mix Base(A) and Solidifier(B) together thoroughly according to strict mixing ratio until the mixed material appear to homogeneous color, then the mixed material can be painted to the prepared surface.
  Mixing ratio:
  WB-1(weight ratio) A:B=7:1 (volume ratio) A:B=5:1
  WB-2(weight ratio) A:B=6:1 (volume ratio) A:B=5:1
  WB-3(weight ratio) A:B=8:1 (volume ratio) A:B=5:1
  3. Curing time: at normal temperature(20℃) the curing time is 4hr; after 8hr it can be normally used or machined.
  Corrosive performance: it can be used in a majority of acid, alkali, salt and some organic acid for a long time.
