Go to top

Each adhesive product manufactured by Coastal Enterprises is made especially for use with Precision Board Plus High Density Urethane and with specific performance characteristics in mind, enabling you to tackle any bonding challenge. We pride ourselves in making our HDU adhesive with the highest of standards in mind. Our satisfaction comes from providing our customers with strong and durable bonds, every time. We set out to create the best adhesive to bond our Precision Board Plus HDU, and after exhaustive work in the lab, our chemists have formulated three products to meet the needs of the artistic and industrial customer alike.

PB Fast Set HDU Adhesive

Our single component adhesive, pb-fast.PB Fast Set is an amber-colored, one part urethane adhesive that fully cures in 30 minutes. It works well for indoor or outdoor applications. PB Fast Set HDU Adhesive cures from liquid to solid with a slight amount of moisture. Use it to join Precision Board Plus High Density Urethane sheets to make them longer or wider, and to laminate sheets together to make them thicker. The consistency of PB Fast Set HDU Adhesive is similar to honey, making it easy to apply directly from the container. Throw out that dipstick, no mixing is required! It works wonderfully on wood, metal and most other materials. PB Fast Set HDU Adhesive is easy to cut, carve, sand and machine, and cuts cleanly. Cure time: Full strength cure 30 minutes. For slower cure and more working time, use PB Bond-240 HDU Adhesive.

Features You Can Count On

  • One step application single component – no mixing required
  • Fully cures in 30 minutes
  • Waterproof
  • Bond sheets together to create sheets of virtually any size and shape
  • Easily laminate sheets or blocks

Quick tips for using PB Fast Set

  • Lightly spray or wipe mating pieces with water just prior to application.
  • Apply just enough PB Fast Set to change the color of Precision Board Plus HDU.
  • Immediately push pieces together.
  • Allow minimum of 30 minutes prior to moving bonded part.
  • Keep adhesive back from outer edge for ease of sandblasting. Clamping is necessary.
  • To blend joint into background after sanding, prime with FSC-88 WB primer/filler.
  • Drill small hole in cap to act as dispensing nozzle. After using, cover hole with tape.

PB Bond 240 HDU Adhesive

pb-240 adhesivePB Bond-240 HDU Adhesive is an amber colored, one part, urethane adhesive that works well for indoor or outdoor applications. It cures from a liquid to a solid state with a slight amount of moisture. Use it to join Precision Board Plus High Density Urethane sheets with butt bonds to make them longer or wider, and for laminating sheets together to make them thicker. The consistency of PB Bond-240 HDU Adhesive is similar to honey, making it easy to apply directly from the container. No mixing is required. Cure time: 4 hours before moving, full strength in 12 hours.

Features You Can Count On

  • One step application – no mixing required
  • More working time – fully cures in 12 hours
  • Quickly butt bond sheets together to create sheets of virtually any size
  • Great for keeping “bone yard” to a minimum
  • Easily laminate sheets to create desired thickness

Quick tips for using PB Bond 240

  • Lightly spray or wipe mating pieces with water just prior to application.
  • Apply just enough PB Bond-240 HDU Adhesive to change the color of Precision Board Plus.
  • Allow PB Bond to slightly bubble and thicken before pushing pieces together.
  • Allow minimum 4 hours cure prior to moving bonded part. Full strength in 12 hours.
  • Keep glue line as thin as possible for ease of sandblasting. Clamping is necessary.
  • To blend joint into background after sanding, prime both joint and background with FSC-88 WB primer/filler.
  • Drill a small hole in cap to act as dispensing nozzle. After using, cover hole with tape.

EP-76 Epoxy HDU Adhesive

ep-76 2-part epoxy adhesiveEP-76 Epoxy HDU Adhesive is a two component epoxy bonding resin. It is designed to bond Precision Board Plus to itself to make longer, wider, or thicker pieces, sheets, or blocks. EP-76 HDU Adhesive is available with a separate container of PB Granules to allow variable consistency and ease of machining. EP-76 HDU Adhesive will not shrink and can be machined, drilled, tapped, sawed, and feathered to a zero edge. It contains no metallic fillers, is a non-conductor of electricity, and will not promote electrolysis.

EP-76 HDU Adhesive is suitable for interior and exterior exposure. The thickness consistency of EP-76 can be adjusted using PB-Granules to allow bonding of both horizontal and vertical surfaces. i.e.: edge bonding and sheet laminating. The durometer hardness and machinability of EP-76 can be adjusted and closely matched to the Precision Board densities by adding PB Granules as outlined in the PB EP-76 HDU Adhesive Product Data Sheet.

Features You Can Count On

  • Permanently edge bond HDU sheets together to create sheets of virtually any size
  • Permanently laminate sheets and blocks to create desired thickness and shape
  • Match durometer hardness and machinabilty to the specific Precision Board Plus density
  • Waterproof bond line

Quick tips for using EP-76

  • Clean and dry surfaces to be bonded thoroughly
  • To increase bond strength, prime entire surface with ungranulated EP-76 HDU Adhesive thinned with 50% acetone and allow to cure thoroughly
  • Mix thoroughly until all streaks of color disappear: mix ratio is 27 hardner to 100 resin.
  • Add granules according match density of Precision Board Plus being bonded. (see chart)
  • Apply EP 76 with a putty knife, forcing material into the Precision Board Plus surface.
  • Pot life (working time for 100 grams) is about 60 minutes at 75°-80°F.
  • Complete cure time: approximately 24 hr.
  • Total and complete mixing is necessary for complete curing. EP-76 HDU Adhesive will remain soft & tacky without adequate mixing.
