Cerez armouring resin

CEREZ resins offer a simple solution to many types of wear issues.
Very easy to process, with high wear resistance, this is an important tool for maintenance services in industries with loaded liquids or bulk material.
CEREZ sticks to most clean stands, appropriately prepared and washed : steel, inox, concrete, polyurethane, rubber, ceramic or existing CEREZ layer.

PROCESSING TECHNIQUES

Key elements to successful application

  • Stand preparation
  • Temperature
  • Resin/Hardener mix smoothness

STAND PREPARATION

  • Stand condition: clean, all grease traces wiped out, and preferably rough
  • Method: grind with large grain wheel or sanding wheel, then rinse with cleaning non greasy solvent

TEMPERATURE

  • CEREZ resin and the part to be coated must be between 15 and 25°C
  • Temperature higher than 25°C reduces setting time and involves difficulties in application
  • Temperature lower than 15°C can slow down or even stop the setting process
  • Warming up: if necessary, heat up every component and the part to be coated by displaying them in a room at the required temperature
  • Caution: do not mix too much product at one time since the Resin/Hardener mix emits heat which can speed up the setting process

MIX

Thick products

  • Work on a clean smooth surface (e.g. stoneware)
  • Drop the right amounts of resin and hardener
  • Mix with a spatula for 3 to 5 minutes

Do not use a tool, soiled with one of the components in the other component’s tin (setting risk).

Liquid products

  • Drop all the hardener in the resin jar
  • Mix 3 to 5 minutes, possibly with a mechanical mixer, very slowly to prevent air bubbles.

Never mix more products than you can apply before the mix sets.

APPLICATION

Thick products

Use metal tools, trowels or spatulas for flat parts and any other appropriate tool for complex shapes (shoe-horn is the best tool for pump housings)

  • Apply a first layer: the mix must get the stand wet, especially if it has been sanded.
  • Apply until you get the desired thickness (respect recommended minimum thickness)
  • Extreme thickness and sloping walls: apply many times if necessary; wait until one layer is totally set before applying the next one
  • Often get your metal tool through the flame of a small gas lamp, in order to prevent the mix from sticking to the tool
  • Formwork making: cover with plastic tape to facilitate demodling
  • Clean tools regularly with acetone before the mix starts to set

Liquid products

  • Apply in cross-layers with a brush or plastic spatula for thicker layers on flat surfaces
  • Always wait until one layer is totally set before applying the next one
  • Applying different coloured layers enables preventive maintenance
