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.

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.

Pressure Sensitive Adhesive

Pressure Sensitive Adhesive

Posted on by admin

What is Pressure Sensitive Adhesive?

Pressure Sensitive Adhesive, also called, “PSA” or  “Self Stick adhesive” is a flexible adhesive that bonds to a variety of substrates when applied to clean and dry surfaces with pressure. Pressure Sensitive adhesive bonds are formed with Pressure –  PSA’s Do Not Require solvent, water, or heat to activate the adhesive. The bond strength is directly influenced by the amount of pressure used to apply the adhesive to the surface.  PSA’s are a great choice for difficult to bond, low energy substrates.

PSA’s are unique because they do not solidify to form a hard material; PSA’s remain permanently tacky and can “Wet-Out” substrates on contact. The bonds are formed by bringing the PSA adhesive in contact with the substrate and applying pressure to form a bond.  PSA’s can be formulated for both – Permanent & Removable bonding Applications.

Benefits of Pressure Sensitive Water-Based Adhesives

Key Features
– Provides a smooth, quiet and magnetic-like peel.
– FDA compliant for direct food contact applications.
– Repositionable.

  • water-based pressure formulated to provide a repositionable seal with little diminishment in seal strength provided there is no contamination of the PSA.
  • FDA compliant for use in direct food contact applications. Seal strengths will vary with
    specific coating, film treatment and processing.
  • Pressure Sensitive Water-Based Adhesives for Resealable Packaging.
  • Reseal available.
  • Slot and roll transfer coat.
  • Permanent and removable pressure sensitivity.
  • Cross-linkable to become stronger or removable.

Cattie Adhesives manufactures a full line of high performance Pressure Sensitives; available in several degrees of Color, Peel Strength, Tack, Shear Strength and Viscosity.

Our Pressure sensitives can be supplied in the form of a  Water based Acrylic Adhesive, Solvent based Adhesive, Hot melt PSA or UV Radiation Cured PSA.

PSAs make up the largest market share of the adhesives business. Our PSA’s can be formulated as a Permanent or Removable grade adhesive and Bond to a wide variety of substrates. The primary raw materials used in formulating our PSA’s are Acrylics, Silicone, Rubber, SBS, Polyurethane, Vinyl Acetate and Epoxy.

We have the capability to Coat our Pressure Sensitives onto many different substrates including – felts,  films,  foams, release liners,  magnet,  papers,  plastics, and  textiles; for various  Medical Tape  and  Industrial Tape applications.
