Product Introduction:
This product is formulated using linear phenolic epoxy resin, polyurethane-modified epoxy resin, and advanced curing agents, designed and manufactured based on the latest formulation concepts. It features high reactivity, strong adhesion, high cross-link density, and excellent resistance to chemicals, solvents, cathodic disbondment, impact, and high temperatures.
Product Usage:
For internal and external anti-corrosion coatings of water supply pipes used in firefighting systems.
Product Features:
- Excellent adhesion to the substrate.
- Strong anti-corrosion capability.
- Good leveling, high gloss, and dense coating.
- Superior high-temperature cathodic disbondment resistance.
- Extremely strong flexibility, capable of passing the 4/5 flattening and post-grooving tests.
- Good performance in withstanding high and low temperatures.
- Strong resistance to boiling water.
