Polyurethane Adhesives FAQs

Where can I buy polyurethane adhesive in Australia?

Fortis manufactures polyurethane adhesives in Victoria and supplies customers Australia-wide. Selected products, including AD5405 Polyurethane Wood Glue and AD512 Tactile Adhesive, are available online. Contact Fortis for bulk and manufacturing supply.

What is the best polyurethane adhesive for timber?

The best adhesive depends on the working time, timber species and assembly process. AD5105 suits fast assembly, AD5205 suits general woodworking and AD5405 provides extended working time.

What is D4 polyurethane wood glue?

D4 refers to a water-resistance classification for wood adhesives under EN 204. Fortis AD5105, AD5205 and AD5405 are D4 polyurethane adhesives for suitable timber applications. D4 classification does not automatically mean an adhesive is approved for structural timber construction.

What is the difference between AD5105, AD5205 and AD5405?

The main difference is working and clamping time. AD5105 provides approximately 10 minutes working time, AD5205 provides 20 minutes and AD5405 provides 40 minutes. Read the Fortis polyurethane timber adhesive comparison for full details.

Can polyurethane adhesive bond timber to concrete?

Yes, selected polyurethane adhesives can bond timber to correctly prepared concrete. Fortis AD512 is designed for suitable flooring and construction bonding applications, including timber-to-concrete installation.

Which polyurethane adhesive is suitable for composite panels?

Fortis AD5113 is developed for compatible composite and sandwich panel manufacturing, including stainless steel, foam, timber and other selected substrates.

Can polyurethane adhesive be used for flooring?

Yes. Fortis AD512 is suitable for specified timber flooring, rubber underlay and traffic tactile installations. Correct surface preparation and restraint during curing are important.

Are polyurethane adhesives waterproof?

Water resistance varies by formulation and service conditions. Fortis AD5105, AD5205 and AD5405 provide D4 water resistance, but this should not be interpreted as approval for permanent immersion. Refer to the relevant Technical Data Sheet.

Do polyurethane wood glues expand during curing?

Many moisture-curing polyurethane wood glues develop a slight foaming action. Close-fitting joints and appropriate clamping are important. Expansion should not be relied upon to compensate for poorly fitted timber joints.

Can polyurethane adhesives bond steel or stainless steel?

Selected products can bond suitably prepared metals. AD5113 is intended for compatible industrial lamination involving stainless steel, while AD512 can bond selected construction substrates including steel. Compatibility testing is recommended.

Does Fortis supply polyurethane adhesives in bulk?

Yes. Fortis supplies suitable polyurethane adhesives for trade, workshop and industrial manufacturing requirements. Contact Fortis for available pack sizes, bulk pricing and technical advice.
