PPG Dimetcote 9 is a two component moisture curing zinc (ethyl) silicate primer coating with a high zinc content for structural steel.

Features

  • Anticorrosive primer for structural steel
  • Complies with the compositional requirements of SSPC-Paint 20, Level 1
  • Specified for structural joints according to ASTM A325 or A490 Bolts RCSC specification, Class B
  • Suitable as a system primer in various paint systems based on unsaponifiable binders
  • Can withstand substrate temperatures from –90°C (–130°F) up to 450°C (840°F), under normal atmospheric exposure conditions
  • When suitably topcoated provides excellent corrosion protection for steel substrates up to 540°C (1000°F)
  • Can withstand service temperatures up to 650°C (1200°F) when topcoated with PPG HI-TEMP 1027
  • Must not be exposed to alkaline (more than pH 9) or acidic (less than pH 5.5) liquids

Instructions for use

Mixing ratio by volume: binder to zinc powder 77:23

Many of PPG's zinc silicates are supplied as two-pack materials consisting of a container with pigmented binder and a drum containing a bag of zinc powder.

To ensure proper mixing of both components, the instructions given below must be followed

To avoid lumps in the paint do not add the binder to the zinc powder

  • Take the bag with zinc powder out of the drum
  • Shake the binder in the jerrycan a few times to reach a certain degree of homogenization
  • Pour about 2/3 of the binder into the empty drum
  • With the jerrycan now reduced in weight and containing more free space, shake it vigorously to obtain a homogeneous mix with no deposits left on the bottom, and add this to the drum
  • Add the zinc powder gradually to the pigmented binder in the drum and, at the same time, continuously stir the mixture by using a mechanical mixer (keep the speed low)
  • Stir the zinc dust powder thoroughly through the binder (high speed) and keep stirring until a homogeneous mixture is obtained
  • Strain mixture through a 30 – 60 mesh screen
  • Agitate continuously during application (low speed).

The use of a dedicated pump with a constant agitation for a zinc silicate coating is recommended Note: At application temperature above 30°C (86°F) addition of max 10% by volume of THINNER 90-53 may be necessary.
