Aro-Bond 533 Woodworking D3 PVA Adhesive

PRODUCT OVERVIEW

Aro-Bond® 533 meets the requirements of BS EN204 category D3 for water resistance.

Aro-Bond® 533 can be used for many woodworking applications where a high level of water resistance is required, and has been successfully used for hot and cold pressing applications in the manufacture of windows, doors, cabinets, furniture and surface bonding for laminating applications. Aro-Bond® 533 can also be cured using radio frequency equipment.

PREPARATION AND APPLICATION

Ensure that the surfaces to be bonded are smooth, clean and free from dust or other deposits. Wood, plywood, laminated plastics should be of uniform thickness. Some dense hardwoods may require sanding before bonding. For best results the moisture contents of the surfaces to be bonded should be in the range of 7 – 13%, but when pressing at temperatures above 105°C, moisture content should not exceed 10%. Moisture content variation between adjacent components should not be > 3%.

Aro-Bond® 533 should be applied evenly to one substrate using a brush, hand roller or mechanical roller. Adhesive coverage between 80 and 180g sq/m are suitable depending on the surfaces to be bonded. When bonding different timbers, such as teak and high-density hardwoods, the adhesive should be applied to both surfaces of the joint. It should be noted that adhesive spread has considerable influence on both assembly and setting times.

Ideally open assembly time should not be more than 5 minutes.

Lay the items to be bonded together within the workable time and press them for as long a time as is needed to achieve the required handling strength. The pressure should be high enough to ensure contact of the parts over the entire area of the joint. Allow 24 hours for full strength to develop. Higher levels of water resistance form more slowly and should be tested not earlier than 7 days after bonding.

Aro-Bond® 533, like all other PVA adhesives, may tend to show structuring especially in cold conditions. This effect is generally reversible on slight stirring. Additionally, there may be some increase in viscosity, but this will not detract from the application properties or performance.

Handling and Storage

Clean machines, equipment and tools with water before the adhesive dries.

Aro-Bond® 533 should be stored in the original containers in a cool, dry place, at a temperature range of between 5°C and 40°C. In these conditions it has a storage life of at least 6 months. Aro-Bond® 533 must not be allowed to freeze and ideally should be warmed to at least 15°C before use.
