Polyamide Hot-melt Adhesive/Hemming Adhesive (DY-P402)
1.Appearance:
Yellowish round grain with schistose shape
2.Property:
DY-P402 is a general type of polyamide hot-melt adhesive, which is made from dimer acid and polyamine through condensation reaction
at high temperature.
It can dissolve in general organic solvents, the hot-melting
viscosity of the resin is greatly related to the temperature that
it gets.
The polyamide hot-melt adhesive possesses the following advantages,
such as lower viscosity, good fluidity, good flexibility, high
adhesive strength, good media corrosion resistance, good solubility
and fluxing property at low temperature, higher heat stability etc.
3.Application
This type of resin is applied in heat-shrinkable sleeve for
electric cable, sealing material for electrical connection,
cementing or fixing materials for electronic component, bonding
material for package, textile, leather, wood, plastic, metal and
ceramics etc.
