Structural Adhesive

October 2016

Product Description

Vibra-Tite PB3005 is a fast setting, high performance
two part methacrylate adhesive engineered to bond a
wide range of materials including metal and plastics,
especially fiberglass. It offers outstanding bond
strength, is extremely durable, with excellent impact
and weathering properties. Vibra-Tite PB305 greatly
increases the reliability of finished assemblies with
exceptional flexibility, its ability to with stand
extreme temperature fluctuation and thermal cycling,
and resistance to a wide range of chemicals and
environmental conditions.

Application and Handling Guidelines

The product is best used at temperatures between 65
°F and 80 °F. Temperatures below 65 °F will slow
the cure speed of the material and viscosities will be
higher. Temperatures above 80 °F will cause the
material to cure faster and viscosities will be lower.
For consistent dispensing maintain temperature in the
above mentioned range.

For optimum bond strength and to insure maximum
performance in the finished assembly, join parts
together within the specified work time of the
adhesive. Make sure the bond joint has uniform
coverage and that a sufficient amount of adhesive is
in the bond area. It is important to have the adhesive
applied, parts aligned and positioned, within the
established work times for the product. To ensure
maximum performance in the finished assembly parts
should remain undisturbed until the fixture time is
reached.

Clean up is best before the adhesive has cured.
Cleaners containing acetone or Citrus terpene provide
the best results. On cured adhesive repeat use may be
required.
