Harmonization Code : 3907.30.00.40 | Epoxy Mold Compounds containing by weight more than 70 % silicon dioxide

3M 3764-Q

Main features

  • Quadrack-Format Controlled Dispensing
  • Rapid Seconds-Scale Bond Development
  • Flexible Impact-Resistant Bond

Product Description

3M Hot Melt Adhesive 3764 Q is a clear, 100% solids thermoplastic adhesive supplied in Q/Quadrack-stick form for use with compatible hot-melt applicators. Its molten phase wets many plastics, including polyolefins, and the adhesive hardens within seconds as it cools. A 50-second open time provides a controlled interval for positioning parts before bond development. The formulation is flexible at low temperatures, impact resistant, and characterized by good shear and peel strength. It is used for assembly, attaching, securing, repair, potting, panel bonding, wire tacking, bundling, sealing, encapsulating, and packaging across compatible plastic, metal, paper, cardboard, foam, ceramic, glass, PVC, and wood substrates.

Key features

  • Quadrack Applicator Compatibility: The Q-format stick is made for compatible 3M Quadrack hot-melt applicators.
  • Rapid Cooling Set: Bond strength develops within seconds as the molten adhesive cools and hardens.
  • Broad Substrate Bonding: The adhesive bonds many plastics, including polyolefins, plus compatible industrial materials.

Applications

Suitable for assembly, attaching, securing, repair, potting, panel bonding, wire tacking, bundling, sealing, encapsulating, and packaging.

Thermal Properties
Flash Point
The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor. Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source.

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application
