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:
Profile Wrapping
Difficult to Bond-PET,PE,BOPP,UV
Foam & Mattress Fabricating
Furniture & Cabinet Assembly
R. V. and Panels
Woodworking and Picture Frames
General Product Assembly
Our PUR adhesives are available in 5 Gallon Pails, 55 Gallon Drums and 250 Gallon Tote bins, to meet a wide range of user applications.
Best Construction Adhesive: We Tested 10 to Find the Strongest
Construction Adhesive Review
If you’ve recently visited the construction adhesive aisle at a home center, you may have noticed that there are A LOT of different adhesives on the shelves. And with that many choices, choosing the best one for your project can be daunting task.
To help clear up the confusion we decided to find out which of these 10 adhesives were the top performers. In addition to finding out which were the strongest, we also tested which adhesives worked when they were cold and which held the best on wet surfaces.
Jiwei supply professional and honest service.
2 / 16How Much Weight Can Construction Adhesive Support?
Strength is obviously what most would consider the crucial characteristic of a construction adhesive. For our first test we wanted to push each of these adhesives to their breaking point. For this test we stuck with standard multi-surface adhesives.
The test was fairly simple in design. First, we glued blocks of wood and PVC to a plank of 2×10 used a notched spreader to ensure that each block received the same amount of adhesive. Then, we let them cure for 40 hours.
To test the strength of each adhesive’s bond, we hung a 5-gallon bucket from each block and poured in sand using a 1-gallon pail. In order to remove time as a variable we poured in one gallon of sand every 10 seconds. Some of the adhesives held so much weight that we had to add five and ten pound weights on top of the bucket full of sand. When a block finally gave way, we weighed the bucked and recorded the results.
3 / 16Which Construction Adhesive Is Strongest?
The results from our weight test were pretty clear. Across the board, the wood-to-wood connection was stronger than the PVC-to-wood connection, which makes sense because wood is more porous, giving the adhesive more to grab on to. The strongest adhesive by far was the Loctite PL Fast Grab Premium. It held 115 pounds on the wood block and 92 pounds on the PVC block. The next strongest adhesive, Liquid Nail’s Fuze It All Surface, held 100 pounds on the wood and 64 pounds on the PVC. See next page for the full results.
4 / 16 5 / 16Which Adhesive Works in the Cold?
To find out which adhesives worked in the cold, we placed all the tubes into a chest freezer and let them sit overnight. The temperature inside the freezer was 19 degrees. Some of the adhesives required more pressure on the caulking gun trigger than others, but ultimately they either squeezed out or they didn’t, so we rated them as either a pass or a fail. Below are the brands that passed the cold test.
The four adhesives that passed the cold test are:
- DAP Dynagrip Heavy Duty Max
- Gorilla Glue Heavy Duty
- Loctite Power Grip Ultimate
- Liquid Nails Fuze*IT
Which Adhesives Work On Wet Surfaces?
To find out which adhesives worked on wet surfaces we submerged blocks of wood and scraps of plywood in water for about an hour before applying the adhesive. The assemblies were put aside for 24 hours to dry and cure. We were not as scientific on this test in that we did not use the notched spreader to apply the adhesive and we did not test the amount of force it took to make the bond fail. Instead, we just tried to pull the to pieces apart with our hands. If that worked we tried to separate them with a hammer. The adhesives that held passed the test. Check out the survivors below.
The five adhesives that work on wet surfaces are:
- Liquid Nails Ultra Quik Grip
- Liquid Nails Heavy Duty Extreme
- Loctite Power Grip Ultimate
- Liquid Nails Fuze*IT
- Loctite Power Grab HD
