Dow Corning's new assembly sealant

Dow Corning's new proprietary sealant technology combines the production benefits of instant adhesion with the performance advantages of silicone elastomers to increase productivity, improve quality, and reduce costs in industrial assembly.

Dow Corning HM-2500 Assembled Sealant is a patented reactive hot melt silicone that provides very high initial strength, sticks instantly, and then cures into a soft, weather resistant silicone seal with long service life and outstanding results The UV resistance.

“A bottleneck that is often encountered in assembly lines is waiting for the sealant to cure,” said Ross Noel, senior applications engineer at Dow Corning Technical Services. “The HM-2500 provides instant adhesion so that parts can be The processing step moves to the next step and is shipped as soon as the assembly is completed."

Dow Corning HM-2500 has long-term adhesion to PVC, aluminum, spray-treated wood products, high-performance coatings, plastics, and various substrates. It is compatible with most common materials without the need for primers. Long storage time, long service life, and moderate application temperature (121°C) make it easy to use. It has a high viscosity at room temperature, so that the material does not flow easily, reducing the extrusion of the sealant and cleaning trouble.

Moisture-cured, 100% silicone HM-2500 can be optimized for use in automatic dispersion equipment to create a uniform seal that facilitates part-to-part stability, minimizes sealant waste and cleaning, and significantly reduces labor costs .

Pre-pumps and robotic equipment can also be configured through Dow Corning's recommended equipment suppliers.
