PURBOND HBS 309 is a liquid one-component polyurethane adhesive which is particularly useful where highly durable bonds are required for timber applications. PURBOND HBS 309 is manufactured formaldehyde and solvent free.
COMMON USES
Window frames, doors and door frames, laminated timber where environmental or water resistance is required, (such as laminated timber for butchers cutting blocks etc).
BONDS
Timber, including more difficult types such as Rimu.
ADVANTAGES
Structural Grade (AS/NZS 4364:2010)
One component product, no mixing.
Bonded parts can be processed after 75 minutes.
Contains no formaldehyde.
Formaldehyde Standard: JAIA (Japan Adhesive Industry Association) Independent Control Standard
against Indoor Air Pollution.
PROPERTIES
The adhesive requires moisture or humidity to cure into a strong, non-brittle adhesive film.
A slight foaming effect during curing is a normal side effect of the chemical reaction.
PREPARATION
Surfaces must be clean and free from any adhesive-abrasive substances like oil, grease or release agents. For more details see the TDS.
APPLICATION METHOD
Coated surfaces should be pressed together immediately but under no circumstances later than 30 minutes after the application of the adhesive. Minimum press time under conditions of 20°C, 65% relative humidity and 12% wood moisture content is 75 minutes.
