HM1000 is a hot melt butyl insulating glass sealant formulated from synthetic polymers and elastomers. It is designed to provide adhesion and sealing performance when applied as an edge seal in insulating glass units (IGU). The material is developed specifically for insulating glass production, offering fast application, rapid cooling and handling strength within a short production cycle. HM1000 is resistant to UV exposure, temperature variations and moisture.
MAIN PROPERTIES
✔ Hot melt butyl sealant
✔ Single component thermoplastic material
✔ Fast cooling and rapid strength development
✔ Compatible with standard hot melt application equipment
✔ Low moisture vapour transmission rate (MVTR)
✔ Low argon permeability
FUNCTION IN IGU SYSTEM
HM1000 is applied as an edge sealing material in insulating glass units, providing a barrier against moisture ingress and gas loss.
