PU Elastomer Metering for Road-Maintenance Applications
Configured heated preparation, metering and dispensing for selected PU road-maintenance formulations.
The HF-CPUE-2A2B-Cons-Road is a PU elastomer metering and casting configuration for agreed road-maintenance applications. The supplied reference lists prepolymer and BDO processing, heated material preparation, dynamic mixing and controlled dispensing.
Crack or joint geometry, substrate preparation, material viscosity, reaction window and curing conditions define the selected equipment and site procedure. Bonding, movement capability and return-to-service requirements are established for the actual formulation and installation.
Working Sequence
Define Material and Site Conditions
Review the selected prepolymer/curative formulation, repair geometry, substrate condition and available site utilities.
Condition and Calibrate
Establish material temperature, circulation and component delivery for the agreed recipe and operating flow.
Meter, Mix and Dispense
Dynamically mix and dispense the selected PU system through the configured outlet and site tooling.
Cure and Inspect
Follow the material cure procedure and inspect the repair against the agreed application requirements.
Technical Specifications
The listed values are configuration references. Component identities, material temperatures, dosing range, site interfaces and acceptance methods are agreed for the selected road-maintenance formulation.
