Sichuan Chlorosulfonated Polyethylene Paint - Chengdu Chlorosulfonated Polyethylene Coating [Guanpai Manufacturer - Manager Sun: 152^0825^6966] Chlorosulfonated polyethylene paint is a high-performance anti-corrosion coating with chlorosulfonated polyethylene rubber as the main film-forming material, featuring the following characteristics:

Excellent weather resistance: Resistant to UV and ozone, does not chalk or crack during long-term outdoor use, with good color retention.

Strong chemical corrosion resistance: Resistant to acids, alkalis, salts, oxidizers, and various organic solvents, suitable for chemical environments.

Elasticity and flexibility: The coating exhibits rubber-like properties, accommodating thermal expansion and contraction of substrates, and is less prone to cracking.

Water and humidity resistance: High impermeability, suitable for damp or underwater environments.

Long-lasting protection: A single layer provides effective protection, with a service life of 8~15 years.

Easy application: Can cure at low temperatures (applicable even at -20°C), making it suitable for use in cold northern regions.

Main Applications
Chlorosulfonated polyethylene paint is widely used for anti-corrosion protection in harsh environments, typical applications include:

Chemical industry: Protection against acid and alkali corrosion in chemical plants, storage tanks, pipelines, and reaction equipment.

Marine engineering: Resistance to salt spray environments for dock steel piles, offshore wind power equipment, and ship decks.

Municipal facilities: Damp or chemically exposed areas such as bridges, sewage treatment pools, and underground utility tunnels.

Power industry: Areas requiring resistance to temperature changes and chemical corrosion, such as power plant desulfurization towers, chimneys, and cooling towers.

Oil storage and transportation: Applications requiring oil and weather resistance, such as crude oil storage tanks and pipelines.

Application Instructions
Substrate preparation:

Steel surfaces must be sandblasted to Sa2.5 grade or power-tool cleaned to St3 grade; concrete surfaces should be clean, dry, and free of oil.

Paint mixing:

For two-component products, mix the base and curing agent in the specified ratio, stir thoroughly, and let stand for 10~15 minutes for maturation.

Application method:

Brushing, rolling, or airless spraying can be used. Recommended dry film thickness is 80~120μm per coat, typically applied in 2~3 coats.

Application environment:

Temperature range: -20°C to 50°C; humidity ≤85%. Avoid application during rain, snow, or dew conditions.

Drying time:

Surface dry: 2~4 hours (at 25°C); hard dry: 24 hours; full curing requires 7 days (extended in low-temperature environments).

Coating system:

Heavy-duty anti-corrosion system: Epoxy zinc-rich primer + epoxy mica iron intermediate coat + chlorosulfonated polyethylene topcoat.

Simple protection: Direct application of chlorosulfonated polyethylene paint (ensure substrate cleanliness).
