Dow Corning HM2500 assembly sealant provides as much immediate adhesion as double-sided pressure sensitive adhesive tape, then cures to a flexible, weather-resistant silicone seal.
Industrial consumables specialist RW Greeff now offers new exclusive sealant technology from Dow Corning Corp that combines the production benefits of instant adhesion with the performance benefits of silicone elastomers to increase productivity, improve quality and reduce costs in industrial assembly applications.
A patented reactive hot-melt silicone, Dow Corning HM2500 assembly sealant provides as much immediate adhesion as double-sided pressure sensitive adhesive tape, then cures to a flexible, weather-resistant silicone seal with outstanding durability and ultraviolet resistance.
According to RW Greeff, assembly lines often suffer bottlenecks waiting for sealants to cure and HM2500 provides immediate hold so users can move parts from one processing step to the next without delays and ship them as fast as they can be produced.
Dow Corning HM2500 provides long-lasting adhesion to PVC, aluminium, painted and treated wood, high-performance paints, plastics and various substrates.
It is compatible with most common component materials without needing a primer.
Long open time, pot life and moderate application temperature of 121C offer user-friendly characteristics.
High viscosity at room temperature resists flow of material reducing sealant squeeze out and clean up.
The moisture curing, 100% silicone HM2500 is optimised for use with automated dispensing equipment, that creates a uniform seal for part-to-part consistency, minimises sealant waste and cleanup and can reduce labour costs substantially.
