Coolant XSPC EC6, white PC liquid coolant for water cooling systems

XSPC EC6 Opaque white coolant is a ready-to-use liquid formulated for PC water-cooling loops. Designed to circulate through radiators, water blocks and tubing, this coolant combines visible white coloration with engineered additives to protect metal and plastic loop components. The formulation is based on refined vegetable extracts, non-toxic corrosion inhibitors and stable dyes to provide consistent appearance, compatibility and thermal performance without requiring additional mixing or preparation.

Advantages

EC6 Opaque offers a stable, non-separating white colour that remains uniform during operation, reducing the need for frequent visual maintenance. The coolant is pump-friendly and free from zinc oxide and titanium dioxide, minimising the risk of clogging and sediment build-up in fine channels and microfins. It provides broad corrosion protection for common loop materials including copper, brass, steel, nickel and aluminium and has been tested for compatibility with acetal and acrylic plastics. Low electrical conductivity and a formulation that supports good thermal transfer make it suitable for performance-focused builds while maintaining visual aesthetics.

Suitable for

• Closed-loop PC water-cooling systems
• Custom liquid cooling loops with radiators, pumps and blocks
• Systems requiring visible white coolant for styling or monitoring
• Maintenance tasks: filling, topping up and fluid replacement

Key specifications

• Ready-to-use liquid coolant formulated from refined vegetable extracts
• Stable opaque white colour that resists separation
• Contains non-toxic corrosion inhibitors and dyes
• Low electrical conductivity
• Designed to be pump-friendly and non-clogging (free from zinc oxide and titanium dioxide)
• Compatible with copper, brass, steel, nickel, aluminium and tested with acetal and acrylic plastics

How to use

Ensure the cooling loop is clean and free of residues before filling. Shake the bottle gently if needed, then pour the ready-to-use coolant into the reservoir or fill port while the system pump circulates to remove air pockets. Monitor the loop for leaks and allow the coolant to run for a short period to ensure uniform colour distribution. For topping up, add small amounts while the system is off or running at low speed to avoid introducing air. Replace the fluid according to your maintenance schedule or if colour or clarity changes are observed.

Recommendations

Use EC6 Opaque in closed-loop PC water-cooling systems only. Regularly inspect fittings, tubing and blocks for signs of wear or contamination, and perform periodic coolant replacement as part of normal maintenance. Avoid mixing this coolant with other fluid brands or concentrates to prevent compatibility issues.
