Heat resiatant anti-corrosive paint for underground pipeline
PRODUCT DESCRIPTION
It is a two-component product composed of epoxy resin, modified phenolic resin, new ST anti-rust pigment, filler, anti-rust additive and mixed solvent. Significantly, this paint, which has good chemical stability, is resistant to alkali, acid, heat, and moisture.
Typical Uses:
This product is applicable to the outer wall of various buried steel pipelines including heat supply network and liquid storage tank. Meanwhile, it is used to protect against corrosion of the steel structure and concrete underwater or at the alternation of wetting and drying.
Application Guide
● Mixing:
Use the power mixer to mix the main paint evenly, and then as you stir it, you add the hardener until you get to mix well. Generally, if the temperature below 10℃, it needs 30 min induction time; if the temperature over 10 ℃, it needs 15 min induction time.
● Mixing Ratio:
Part A: Part B=20:5 (by weight)
● Thinner:
Exclusive thinner.
● Airless Spray:
Nozzle tip: 0.018~0.025 inches.
Spray pressure: 18~25 MPa.
Thinner ratio: 0~15% (by weight of paint).
● Brush, Roller:
Recommended for small areas only.
Must achieve required thickness.
