RepaCoat CH is a liquid, cold-curing expoy formulation with excellent chemical resistance achieved through the use of special resins, as well as additives and inert fillers. RepaCoat CH is particularly suitable as protection against mixtures of aggressive chemicals.
Typical applications
2-component coating with an excellent resistance to aggressive chemicals in:
Tanks, tubes, pipes and pumps
Chemical industry, oil industry
Refineries
Exhaust systems
Characteristics
Protects the base material from aggressive media
Resistant to most inorganic acids and at the same time against aggressive organic acids
High resistance to solvents
demonstrably increases the service life of pipes, pumps and tanks
Easy application by brushing or spraying
Retention / Shelf life
store in original, unopened container dry, cool and frost-free (+5°C to +20 °C) . Shelf life 2 years. Protect from direct sunlight. High temperatures reduce shelf life.
Preparation / Surface condition
Roughening of the surface by sandblasting (preferably) or grinding, up to a roughness depth of 100μm +/- 20μm, blasted sharp edges (blasting material G). Recommended surface preparation grade Sa 2,5.
Processing parameters
The processing time (potting time) of the material begins as soon as the two components A and B have been completely mixed with each other by means of a mixing coil. Potting time and curing time depend on the amount of material (volume) and temperature. With larger containers, the potting time may be reduced due to a higher reaction heat. The material hardening can be accelerated by heating. The maximum permissible temperature for accelerated curing is 50°C. The required curing temperature is 5°C . At low temperatures it is recommended to preheat the components.
Application
RepaCoat CH can be brushed, rolled or sprayed. The optimal spraying conditions must be determined individually in preliminary tests (generally good results are obtained when heated to approx. 50°C and 200 to 300 bar). The minimum application thickness is 350μm. If a second layer is applied, an optimal bond to the first layer is achieved if the first layer has reacted at least 1.5 hours. In case of subsequent vibration loading, the layer thickness should not exceed 1mm. Deeper excavations in the object should be done with RepaCoat CH 40 P # 2111.
Mixing
To mix RepaCoat CH, Component B is placed completely in the container with Component A. Mix intensively with a hand drill and the Diamond Mixing Propeller #0789. Wipe off material sticking to the wall of the container with a spatula and mix. Mix again thoroughly.
