What is Liquid PUR Adhesive?

Liquid PUR (Polyurethane) adhesives are reactive moisture curing adhesives known for Strong Bonds and Exceptional Heat, Cold and Moisture-Resistance; this makes liquid PUR adhesive an excellent choice for most difficult to bond, low energy substrates and they perform very well in extreme weather environments.

Liquid PUR – One-component Cold Liquid moisture-cured polyurethane adhesives

– Our version of Industrial Strength  “Gorilla Glue”.

Our Liquid PUR adhesive forms permanent bonds by a chemical reaction with moisture from the substrate or environment.

These “Cold” Liquid PUR adhesives are liquid at room temperature so bonded parts must be pressed together and held during the curing process.

Standard Features:

• Great for wood, metals, ceramics, most plastics, HPL, Corian, stone and most porous/nonporous materials.
100% waterproof adhesive that bonds almost everything.
Epoxy like strength; no mixing and fast cure time.
• Excellent Sandability.
• 100% solids and solvent free.
• Assembly time after glue application: 20-30 minutes.
• Application temperature: Above 50°F.
• Viscosity range: 4,000 – 10,000 cps.

Liquid PUR adhesive forms structural bonds to most difficult to bond substrates, and are especially good for gluing materials such as – carpet, wood, foam, metal and most plastics to each other. It is Not recommended for vinyl (PVC), polypropylene, polyethylene and polyolefins. Liquid PUR produces extremely durable, highly elastic bonds that perform well in both high and low temperature extremes.

Our Liquid PUR adhesives can be Custom Formulated to have Very High Initial Tack and a Very Fast Set up time from a few seconds, or up to Several Minutes of Open Time before setting up.

After Liquid PUR adhesive has been applied to a substrate it will start to cross-link and form a final bond. Depending on air humidity and substrate moisture conditions, PUR adhesive develops 50-80 % of its final bond strength in approximately 3 – 6 hours. The full reactive cure time is normally 24 to 36 hours after application.

PUR adhesives cure to a thermo-set material, maintaining their structural integrity once cured. PUR Adhesive has excellent temperature and environmental resistance – withstanding exposure to temperatures from -40°F to +300°F.

Our PUR adhesives are commonly used to bond Steel to Foamed polystyrene in large bonding areas. PUR adhesive is considered to be the best and most cost-effective adhesive for these types of applications. PUR adhesives are cured by reaction with atmospheric moisture to form a cross-linked thermoset system.

PUR adhesives can be formulated to have different open times and different rates of bond strength buildup. PUR adhesives are widely used for the bonding of large panels, such as in door manufacturing, garage door construction and the walls of recreational vehicles. PUR is also commonly used for laminating foil to sheet metal for the production of cans and bottle caps.

For bonding Large areas – Spraying or Roll Coating are often the best application methods for PUR adhesives.

PUR adhesive forms very strong permanent bonds to most materials including:

Solid Woods,  MDF/Particle Board,  Metal, Paper, Glass,  Wooden Veneer,  Clear Plastic Boxes,  Plastics,  PVC,  Foils.

Are you considering a PUR adhesive vs. Solvent based adhesives?

Polyurethane Adhesives (PUR) should be seriously considered when switching away from a Solvent-based adhesive system. PUR adhesives have numerous advantages over solvent-based adhesives.

The primary advantages of using PUR adhesive include:

The reduced cost of the adhesives, on a /lb. basis.
NO HAP’s or VOC’s, 100% Solvent Free.
The elimination of a plant explosion risk; lower insurance costs.
No more need for air pollution control devices.
The removal of dryers in the production line.

Some considerations on PUR  vs. Solvent-based adhesive:

The initial expense of new equipment to apply the PUR.
The special handling and fast clean up requirements with PUR.
PUR is more prone to cross linking and has lower resistance to solvents.

Our PUR adhesives are commonly used in the following Applications:
