POLY-BOND B39 – TDS 1/3
POLY-BOND B39
Polyester-Based Pumpable General Purpose
Adhesive
Introduction
Poly-Bond B39 is a high strength pumpable polyester adhesive formulated for production environment in boatbuilding
and general fiberglass fabrication.
Main Features
High-strength adhesive for poly/vinylester laminates
Reliable strength in thin and thick bondlines
Excellent wet-out of surface – strong bonds to poly/vinylester laminates
No volume loss during pumping
Hangs well on vertical and inverted surfaces
Stacks well on top of stringers
Long geltime and fast cure for quick demolding
Fast pumping speed with low pumping pressures
B39 was formulated to provide reliable structural bonds in both thin and thick bondlines (1/8 to 1 , 3 25mm). B39 has
low shrinkage, low exotherm and no volume loss during pumping. The long geltime and fast cure make it ideal for the
bonding and quick demolding of large parts such as fiberglass overhead and interior liners and molded structural grids.
B39 hangs well on vertical and inverted surfaces, and stacks well on top of stringers. For bondline thickness of 1 (25
mm) and less, the exotherm is low, reducing the chance of print-through in thin laminates. B39 can also be used for hull-
to-deck joints and strake filling. B39 uses MEKP catalysts, and is available in S (Summer) and W (Winter) grades.

Catalyzation
5 Gallon Pails: Mix contents before catalyzation with a paddle type mixer. After catalyzation, mix again, with care to
scrape edges and bottom of pail. If low temperature prevents a complete cure, increase shop temperatures, not the
catalyst level. Assure that parts to be bonded have reached shop temperature. Drums: Poly-Bond B39, B39HP is
dispersed from the drum by gun application, with internal mix catalyst systems. Dispension guns are supplied by:
Magnum Venum Products, www.mvpind.com; GS Manufacturing, www.gsmfg.com; Glas-Craft, www.glascraft.com.
Surface Preparation
Surface to be bonded should be dry, clean and free of dust, oil or grease. Check resin system for secondary bonding
time window to obtain a chemical bond. If surface is sanded, assure that no dust remains. Vacuum surface rather than
using an airhose which only redistributes the dust. Avoid cleaning surface with solvents.

Poly-Bond B39 W (Winter) Catalization Chart. 50 – 60 Minute Geltime
These catalization charts have been generated from laboratory conditions and a constant controlled setting. Specific Gravity of the Poly-
Bond B39 is 1.05 g/cc. The laboratory moisture level is less than 20% during these tests. Humidity will affect the results shown above.
The information contained in this chart should be used as a base point. Geltimes must be confirmed at shop conditions for use in
production environments.
Shelf Life
Poly-Bond B39 is a stable products, and adequate long-term storage conditions will result in a shelf-life of 12 months or
more. After this time, the geltime may drift, and should be checked before use.
Storage
The product should be kept in securely enclosed containers. Storage should be in a dry place out of direct sunlight. The
temperature should be between 65-77 F (18-25 C). Allow Poly-Bond to reach shop temperature before using. Keep
containers closed to eliminate styrene evaporation, and to avoid change in properties of the material.
