Flooring & bus frame adhesive

30/04/2024

Table of Content

Industrial adhesive helps optimize the process of bonding floor panels to the floor frame, floor coverings, sealing, and sealing the bus floor. Depending on the application and the overall performance needs of the vehicle, the choice of adhesive will need to consider:

Flexibility.
Cut resistance.
Tensile strength.
Vibration resistance.
Fatigue resistance.
Aesthetics.
Temperature range.

Superior advantages of adhesive over traditional methods

Adhesive provides a very strong bond and can also reinforce like epoxy adhesive better than rivets and welding in terms of stacking durability.

Adhesive is more elastic with lower cross-linking, thereby providing better flexibility, higher durability, and fatigue resistance, allowing for expansion and contraction with temperature changes.

In transportation vehicles, where floor panels are bonded to the floor frame, adhesive joints may be exposed to outdoor conditions (for some open-design types), requiring higher durability and weather resistance.

The aesthetics of the floor should not be underestimated. When assembling thin materials such as floor coverings, it is important to select the appropriate combination of adhesive and materials along with the suitable installation process to avoid deformation during or after assembly.

Adhesive comes in various levels of elasticity, hardness, and shear strength, suitable for various sizes and different load-bearing requirements of various types of floors and bus frames.

Selecting the appropriate adhesive for different substrates

Floor panels and coverings come in various substrate types, often made from vinyl, polyolefin, rubber, or polyamide. Key factors influencing the choice of floor panels may include aesthetics, durability, flexibility, weight, slip resistance, moisture absorption, comfort, soundproofing, fire/smoke/toxicity resistance, ease of installation, and cleanliness.

The increasing shift towards more sustainable solutions may lead to a higher proportion of natural or recyclable substrates. Floor coverings can be applied onsite or provided in the form of self-adhesive roll tapes.

Floor coverings can be applied to composite floors, aluminum floor panels, laminated floor coverings, or subfloors made of plywood.

Plywood remains the most commonly used material for bus flooring, but bus manufacturers are increasingly interested in lightweight and moisture-resistant alternatives, such as panels made from synthetic materials with foam cores, honeycomb aluminum panels, or even aluminum sheets.

Choosing the appropriate adhesive:

Type of Adhesive	Silane Modified Polymer	Polyurethane/Epoxy Adhesive	Water-based Adhesive (spray)	Solvent-based Adhesive (spray)
Main Value	Solid 100%, can be applied manually, repositionable initially, safe & low toxicity	Gap filling, high load bearing, self-leveling on surface, can be repositioned initially	Convenient spray form, safe & low toxicity	Convenient spray form, instant adhesion
Main Limitation	Curing time to achieve full adhesion is 1mm/24h	Contains Isocyanates or Bisphenol related to environmental issues	Limited thickness, compatibility with substrate needs to be checked	Limited thickness, shrinkage, environmental safety issues of solvents
Handling	Easy, no mixing required	Difficult to mix, requires mixing, long curing time	Convenient spray form	Easy application, requires protective gear
Performance	Elastic, non-shrinking, long-lasting, moisture resistant	Harder, stronger, and better resistance to various conditions	Good resistance	Good resistance
Aesthetics	Average aesthetics	Good aesthetics (self-leveling) but may cause cracks at joints	Average aesthetics when finished	Average aesthetics when finished
Maintenance	Can be removed with tools	Difficult to remove	Can be removed with tools	Can be removed with tools
