ComStar International has announced that it will increase the production and marketing of Metal Lock Black, an innovative “no heat” solder for use in pipes and fittings of all types of metals.
The revolutionary polymer solder can be applied easily and it is permanent and rapid to test pressure. The product is ideal for applications where hydrocarbon refrigerants are used to repair systems. The Metal Lock Black is the latest addition to ComStar’s portfolio of individual chemical products.
The Metal Lock Black is non-toxic and provides protection against gases, fluids, refrigerants and chemicals. It creates a permanent leak-proof seal within seconds. It has a capacity to bear shear pressure till 2,200 psi and operates at temperatures ranging from –65oF to +350oF. The Metal Lock Black satisfies numerous specifications of the US military.
The Metal Lock Black can be applied on various metals, including brass, copper, aluminum, steel and black iron, as well as on threaded or unthreaded pipes and fittings. For unthreaded pipes and fittings, small amount of no heat solder is applied and the pipe is inserted and rotated to 180 degrees or more. For threaded parts, the solder is applied similar to a normal thread sealant.
Hydrocarbons are used globally in home appliances and will soon be introduced in air conditioners. To service these systems, professionals look for easy-to-use, safe and fast no heat solder. Moreover, current air conditioning systems include joined copper tubes and aluminum coils and these require innovative solution for joining and repairing these different metals. Based on these two reasons, the company has expanded the production of Metal Lock Black.
Autonomous laboratories have tested and approved ComStar’s Metal Lock Black for use with hydrocarbon refrigerants. The innovative no heat polymer solder is now available via a network of HVACR and home appliance wholesalers in the U.S. and will soon be available globally.
