Instructions for the use of pavement adhesive

2019-08-29

Before construction, it is necessary to familiarize yourself with the usage of pavement adhesive. Only by following the correct method can the expected results be achieved. Below, Huitian New Materials will guide you to understand the precautions for using pavement adhesive!

Curing of pavement adhesive. The curing requirement for pavement adhesive is that the main agent and curing agent do not immediately have high bonding strength after composite processing. The product needs to be placed in a curing chamber for 24-48 hours. However, it should also be noted that the working environment in winter and summer is different.

Drying of pavement adhesive. To ensure that the solvent on the coated pavement adhesive film completely evaporates, it is important to have sufficient airflow, wind speed, and temperature.

Composite pressure of pavement adhesive. The composite pressure of pavement adhesive should be increased as much as possible without damaging the film.

Coating amount of pavement adhesive. For composite films that require thermal processing or molding processing, the amount of adhesive applied is larger; conversely, it is smaller. For printed films, the amount of adhesive should be adjusted accordingly!

Working concentration of pavement adhesive. The working concentration is determined by the concentration of the adhesive on the flower roller. The higher the concentration, the better the economy.

Dilution method of pavement adhesive. The dilution method for polyurethane adhesive involves adding solvent to the main agent according to the required solid content, stirring, and then adding the curing agent to the diluted main agent, followed by thorough stirring.

Bonding temperature of pavement adhesive. The bonding temperature of pavement adhesive depends on the properties and quality of the composite substrate, using the highest possible temperature.

Shelf life of pavement adhesive. The shelf life of the prepared pavement adhesive is determined by the solid content of the adhesive, storage temperature, and moisture in the diluent. Generally, the prepared pavement adhesive can be stored in a sealed container for one to two days. Pavement adhesive that exceeds the shelf life will negatively affect the quality of composite products!

The above are the precautions for using pavement adhesive. If there are any unclear areas, feel free to consult the adhesive Manufacturer Huitian New Materials online.
