Process Step

Guidelines

Surface Preparation

The strength and durability of the bond is dependent on proper surface treatment of the tyre surfaces to be bonded.

The tyre surface should be buffed and cleaned prior to application of the adhesive. All surfaces to be bonded should be dry, clean and free from dust, grit, wax, grease or oil before hand.

Adhesive Application

A2024 can be applied using a conventional air assisted spray gun system that must not contain any brass or copper parts.

The A2024 adhesive should be applied evenly to the tyre, ensuring that no runs or drips are present. Drips or runs slow down the drying process.

The tyre is ready to retread when the adhesive film has completely changed from white to clear with no white specks present. If the tyre is retreaded when white specks are present the new tread will blow at the points where there was water present.

Curing

Bonded assemblies should be left for 7 days before physical testing is conducted.

Cleaning

For wet material, it is advised that any spillages be cleaned up immediately with soapy water before the adhesive can fully dry.

HEALTHY & SAFETY INFORMATION

Alpha A2024 is not classified as hazardous according to Directive EC 1272/2008. Please refer to the Alpha A2024 Safety Data Sheet for further health & safety information.

STORAGE

Alpha A2024 should be stored in its original container, with the lid tightly secured, in dry conditions and at temperatures between 5°C and 25°C. Alpha A2024 will keep satisfactorily for up to 12 months from date of manufacture if stored according to the recommended conditions.
