Solid Aluminum Panel

The raw material of WEICHU brand curtain wall aluminum solid panel is high quality A3003 aluminum-manganese alloy or A5052 aluminum-magnesium alloy. The surface of the aluminum panel is chromium pretreated, then PVDF coating. We offer two kinds of coating: PVDF and vinylidene fluoride resin varnish (KANAR500). The usual way is stain primer, binding primer, surface primer, then finishing. The characteristics of PVDF coating are Strong weather resistance, good self-cleaning performance, excellent corrosion resistance, weather-resistant, acid and salt fog resistance, can resist strong ultraviolet radiation, Excellent in heat insulation and non-resonance, Easy maintenance, Can be applied to external decoration, balcony partition pillar, interior decoration and advertisement board.

PVDF resin painting principle

• The use of fluorocarbon resin PVDF in the solid aluminum panel are the aliphatic hydrocarbon molecular structure by fluorine atoms replace some hydrogen atoms of polyvinylpyrrolidone

• Has the maximum negative charge of fluorine (F) atoms and carbon(C) atomic fluorine carbon bond force up to 105.4kcal/mol this is the means to destroy fluorine carbon combination requires at least 105.4kcal/mol more energy.

• Fluorine carbon combination distance is 1.36A, the distance than carbon carbon combined with 1.54A and short distance. Steric hindrance caused by fluorine atom, its structure is very tight, difficult to damage with fluorine carbon.
