What is PUR Hot Melt Adhesive ?
PUR Hot Melt Adhesive (Polyurethane) is a reactive moisture curing adhesive known for – Strong Bonds and Exceptional Heat, Cold and Moisture-Resistance; this makes them an excellent choice for most difficult to bond, low energy substrates and they perform very well in extreme weather environments.
Our PUR Reactive Hot Melt Adhesives can be Custom Formulated to have a Very High Initial Tack and Green Strength.
After PUR Hot Melt 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 Hot Melt develops 50-80 % of its final bond strength within 3 – 6 hours. The full reactive cure time is normally 24 to 36 hours after application.
PUR Hot has a Wide Temperature performance range – From: -40°F to + 300°F.
Cattie Adhesives manufactures a full line of PUR Reactive Hot Melt Adhesives for Industrial applications. We have the knowledge and experience to help you design and scale-up your PUR hot melt adhesive production and help to improve your production speed, accuracy, efficiency and consistency.
Our PUR Hot Melt Adhesives are designed to form very strong permanent bonds to most materials including:
- Solid Woods, Veneer
- MDF/Particle Board
- Metals
- Papers
- Glass
- Fiber Glass, Foams
- Plastics, Rubber
- PVC, Foils
Our PUR Hot Melt Adhesives can be Custom Formulated for Strong, Fast setting-Permanent bonding applications; or Slower setting applications. We have the ability to produce pigmented reactive hot melt adhesives, pre-polymers, and other custom products.
Our PUR Hot Melt Adhesives can be used with most Hot Melt Applicator Systems and are made to bond to most difficult substrates including – fiberglass, nylon, plastics, rubber, foam and coated papers.
PUR Hot Melt adhesives are applied molten like a conventional hot melt, but then cure by reaction with atmospheric moisture to form a cross-linked thermoset system.
PUR Hot Melts are fast drying and most bonded parts have the Green Strength to be handled after a few minutes.
PUR Hot Melt adhesives are widely used for the bonding of Large Panels, such as SIP Panels, Door manufacturing, Garage door Construction and the walls of Recreational vehicles.
PUR Hot Melt is 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 Hot Melt.
PUR Hot Melt does Not bond well to Untreated PolyEthylene (PE) or PolyPropylene (PP).
It is suggested that PE and PP are Corona treated, to improve the bond strength to these substrates.
Hot Melt Adhesive
What is Hot Melt Adhesive?
Hot Melt Adhesive is a Solvent-free adhesive made from 100% non-volatile thermoplastic materials, hot melt adhesives are solid at room temperature, melted to application temperature and applied in a molten state.
Hot Melt Adhesive is applied as a Hot Bead, Dot or Molten Film and forms into a solid material when the hot melt cools down below its softening point.
All our hot melt adhesives are formulated to provide desired adhesion, fast set speed, open time/bonding range, and heat and/or cold resistance properties.
Hot melt adhesives are available in pellets, micro-chips, chips, pillows, and stick form.
Some Key benefits of using Hot Melt Adhesive:
Hot melt Adhesive is 100% solid and environmentally friendly.
Hot melts have Fast Set Speed to allow for higher speed production lines.
Hot melt adhesives are Water resistant and provide excellent Glue Line Control.
Hot melts have a Long shelf life and do not require any special storage conditions.
Hot melts stick to almost any substrate and provide great final bonds.
Hot melts can be formulated to have long open time and can be used for – High Heat bonding and Deep Freeze gluing applications.

Heat Seal Adhesives
Cattie Adhesives – Heat Seal Adhesives
What are Heat Seal Adhesives?
Heat Seal Adhesives & Coatings or Heat Seal Films are Hot Melts or Liquids that are applied to paper, film, non-woven or foil substrates and Dried. The final bond is not formed until the Heat Seal Adhesive is later – Re-activated.
Cattie Adhesives manufactures a Full Line of Hot Melt Heat Seals, Heat Seal Films & Tapes, Water based Heat Seal & Solvent based Heat Seal Coatings for many industrial – Food Packaging, Flexible Packaging, Paper Converting and Specialty Applications.
Our Heat Seal Adhesives & Coatings can be applied by different methods including – Knife over roll, reverse roll, nip roller, gravure, brush, spray or roller.
The Heat Sealing process can be performed Both In-line or after initial application.
Our Heat Seals can also be Custom formulated for specialty applications to meet requirements for – viscosity, solids %, non-blocking, clarity & heat sealing temperature.
We also have the capability to Coat our Heat Seals onto many different substrates including – felts, films, liners, magnet, papers, plastics, and textiles; for various medical and industrial applications.
