Produk Pendahuluan:
This is a thermosetting epoxy-modified heavy-duty anti-corrosion powder coating specifically designed for epoxy-coated reinforcing steel. The product uses imported two-step special epoxy resins, functional epoxy resins, and dedicated anti-corrosion curing agents. It features excellent reactivity, strong adhesion, good toughness and flexibility, and superior resistance to chemicals, solvents, cathodic disbondment, and impact. The formulation has been tested and proven effective by authoritative departments.

Standar Kepatuhan: JG 3042-1997; GB/T 25826-2010
Fields aplikasi:
Bridges, ports, airports, buildings, basements, high-speed railways, and other infrastructure projects.
Aplikasi Proses:
Penyemprotan elektrostatik.
Kewaspadaan:
The reinforcing steel surface should be free of oxide scale, revealing the metal’s original color; the surface roughness should meet the standard, ideally 50-70 mm; the rust removal grade should reach Sa2 1/2 level (GB/T 8923), with no chloride residues. Preheating temperature should be controlled between 220-245°C.
Produk harus disimpan di ruangan dalam ruangan yang kering dan berventilasi baik dengan suhu di bawah 27°C, jauh dari sumber panas, bahan kimia korosif, dan pelarut kimia, serta terlindung dari paparan cahaya yang kuat. Tinggi penumpukan tidak boleh melebihi empat lapis. Hindari tekanan jangka panjang dan pastikan kotak kemasan tertutup rapat untuk mencegah penggumpalan dan kelembapan, yang dapat memengaruhi kinerja fluidisasi.
Due to the high reactivity of this product, the recommended storage period is within 3 months at 27°C. If used beyond the storage period, the performance should be verified in advance.
