How to make instant radiator leak sealant powder

Radiator Leak Sealant Powder is a high-performance cooling system additive specially formulated to seal minor leaks in automotive radiators and cooling systems quickly and effectively. When added directly to hot engine coolant, the powder disperses throughout the cooling system and is carried to leak points where heat and pressure activate the sealing process, forming a durable temporary seal over pinholes, hairline cracks, and small seepages. The formulation is designed to remain suspended in the coolant without clogging radiator passages or restricting coolant flow under normal operating conditions. Once the powder reaches the leak area, it reacts to create a stable sealing layer that helps prevent further coolant loss while allowing the cooling system to continue operating efficiently. This formulation package includes three different commercial formulas, each developed for specific cooling system applications and manufactured using economical and commercially available raw materials.

Formula Package Includes:

• Radiator Leak Sealant Powder Formula (1).

• Radiator Leak Sealant Powder Formula (2).

• Radiator Leak Sealant Powder Formula (3).

Applications:

• Automotive radiators.

• Passenger car cooling systems.

• Heavy-duty vehicle radiators.

• Industrial engine cooling systems.

• Small pinhole leaks.

• Hairline cracks.

• Minor coolant seepage.

• Preventive cooling system maintenance.

Formula Features:

• Three complete commercial formulations.

• Fast-acting leak sealing performance.

• Activated by heat and coolant pressure.

• Effectively seals pinholes and small cracks.

• Excellent suspension in engine coolant.

• Does not significantly restrict coolant circulation when properly used.

• Compatible with most water-based coolant systems.

• Easy to add directly into the radiator.

• Manufactured using economical and commercially available raw materials.

Typical Formula Performance:

Appearance: Fine free-flowing powder.

Application Method: Added directly to hot radiator coolant.

Activation: Heat and pressure activated.

Leak Sealing Performance: Effectively seals minor radiator leaks, pinholes, and hairline cracks.
