Grade:VF790
Product: Hot Melt Adhesive Resin For Aluminum Plastic Panel And Heat Insulation Panel
Descriptions
Hot melt adhesives (HMA), also known as hot glues, are 100% solids formulations based on thermoplastic resins. They are solid at room temperature and can be softened, reshaped, and dispensed upon heating above their softening point. Solidification typically takes only a few seconds after dispensing and once cooled to room temperature, these thermoplastic adhesives reach full strength. This minimizes clamp time and allows for rapid assembly. Hot melt adhesives are also easy to clean with low to no toxicity and the application and bonding can easily be automatized. Furthermore, they have excellent gap filling capabilities and bond a wide variety of porous and non-porous substrates including pre-painted steel and polyolefin plastics.
VF790 is a maleic anhydride and vinyl acetate functionalized polyethylene mixture, easy to form film, with excellent processability and adhesive strength.
