Topstick TPU: PVC and Polyurethane Adhesive for Conveyor and Component Repairs
Topstick TPU is a two-part PVC and polyurethane adhesive designed for industrial bonding applications that require strength, flexibility, and lasting durability. It performs exceptionally well in the repair of PVC conveyor belts, polyurethane linings, and other high-wear industrial components.
This two-component system cures quickly and provides excellent chemical resistance — ideal for material handling, manufacturing, and conveyor maintenance operations.
Bonding PVC or polyurethane effectively requires an adhesive specifically engineered for those materials. A PVC and polyurethane adhesive ensures strong, permanent bonds where generic solutions often fail.
Topstick TPU offers:
Superior adhesion to flexible PVC and PU surfaces
Two-part formulation for increased bond strength and reliability
Ideal for splicing, joining, or patching damaged sections
Excellent performance under dynamic loads and chemical exposure
Free from trichloroethylene and fast curing time
In addition, its balanced open time gives technicians flexibility during repairs without compromising curing speed.
Applications of Topstick TPU
Topstick TPU is trusted across multiple industrial sectors, including:
PVC conveyor belt splicing and repair
Polyurethane lining patching on hoppers, chutes, and pipes
Flexible ducting and PVC hose bonding
Polyurethane roller or bumper assembly
Heavy-duty bonding in chemical processing plants
Tip: For best results on metal substrates, use Topprime metal primer before applying TPU.
How to Use Topstick TPU Effectively
Topstick TPU is trusted across multiple industrial sectors, including:
Surface Preparation
Clean, dry, and abrade both surfaces to be bonded. Use primer for metal surfaces.
Mixing
Mix resin and hardener thoroughly in the specified ratio until uniform.
Application
Apply evenly to both surfaces. Allow flash time before mating parts.
Bonding & Curing
Press parts together under pressure. Full cure develops over 24–48 hours depending on conditions.
Note: Always consult the technical datasheet and MSDS before application.
Important
Topstick TPU is a flammable product and therefore should be used above-ground only and not near any source of ignition.
