PERMABOND TA4611

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

PERMABOND TA4611

Main features

  • Microbead-Free Small-Gap Bonding
  • Primer-Free PP and PE Assembly
  • Controlled 0.5 mm Gap Filling

Product Description

Permabond TA4611 is a two-part, 1:1 toughened acrylic adhesive developed for polypropylene and polyethylene without primer or costly surface treatment. Its microbead-free formulation is intended for joints with smaller gaps while retaining compatibility with selected metals and composites. The transparent to pale-yellow mixed adhesive supports a maximum gap of 0.5 mm. At 23 deg C, typical pot life is 4 to 6 minutes, fixture strength develops in 10 to 16 minutes, and handling strength in 40 to 50 minutes. Cured shear results include 14 N/mm^2 on carbon fiber, 13 N/mm^2 on epoxy FRP, and 8 N/mm^2 on HDPE.

Key features

  • Microbead-Free Small-Gap Bonding: Supports joints up to the 0.5 mm maximum gap.
  • Primer-Free Polyolefins: Bonds polypropylene and polyethylene without primer or costly surface treatment.
  • Dissimilar-Material Assembly: Supports selected metal, composite, and polyolefin substrate combinations.

Applications

Applications include smaller-gap bonding of polypropylene and polyethylene, plus selected metal, composite, and dissimilar-material assemblies.

Pot Life
Pot life is the amount of time it takes for the viscosity of a material to double (or quadruple for lower viscosity materials) in room temperature after a material is mixed. It is closely related to work life but it is not application dependent, less precise and more of a general indication of how fast a system is going to cure.
4-6 minutes
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
