Benefits
The use of structural adhesives brings many benefits:
- Superior Bond strengths
- Eliminate mechanical fastening devices, pre-drilling
- Stronger, lighter finished assemblies
- Improved finished product quality
- Bonds similar and dissimilar materials
- Good impact and vibration resistance
- Excellent aging and weathering. Resist temperature extremes and thermal cycling
- Cost effective
- Full range of work times and cure times
- Toughened, low read-through (LRT) that withstands e-coat & powder coat cycles
Available Technologies:
Silyl Modified Polymer (SMP)
Also known as MS (modified-silane) polymers, silane terminated polymers (STP), are moisture-curing, single component, solvent-free and isocyanate-free sealants and adhesives. Single component, solvent-free and isocyanate-free, SMPs have superior adhesion on a wide range of substrates, and have good temperature and UV resistance. There is no need for cleaners or primers allowing for minimal surface preparation. SMPs can bond directly to glass. SMPs do not shrink, crack or chalk over time.
Acrylic or Methyl Methacrylate (MMA) Adhesive
Acrylic based adhesives are primarily used to bond metals, composites and a large number of thermoplastic materials. They require little to no surface preparation or primers and cure at room temperature. Acrylics offer toughness that delivers impact resistance, excellent low- and high-temperature performance, and desirable in-service fatigue life on top of high structural strength in bonded assemblies.
Epoxy
Epoxy based adhesives can be used on metals, plastics, composites, concrete, wood and foam. Epoxies are generally very strong and chemically resistant. They have a slower cure but can often be accelerated with heat.
Polyurethane
Polyurethane based adhesives are a good choice for bonding plastics, composites, wood and foam. Polyurethanes are generally used for metal bonding applications where the metal is primed, painted or coated. They are available in 1 or 2 components with different work and cure times.
Substrates to be used on:
Metal, Painted Metal, Composites, Thermoplastics, Fiber Reinforced Plastic (FRP), Elastomers, Wood
Applications and Industries:
General Transportation (GT), Trailers, Utility Bodies, Service Trucks, Sign Assembly, HVAC, Containers & Enclosures, Buses and Rail, Recreational Vehicles (RV’s), Recreational Equipment, Aerospace & Defense, Agricultural Machinery, Antenna Dishes, Speaker Assembly, Windows/Doors and Architectural products, Panel Assembly, Marine (deck/hull assembly) and Watercraft, Transportation Skids or Pallets.
