Bonding conditions: The adhesive substrate and ambient temperature should ideally be between 18?C and 20?C. The moisture content of wood materials should be uniform and should be between 8% and 12%. Do not process below 15?C.
Spreading: SIAbond D4 can be applied by serrated glue spreader, roller, brush or by spray. Application is normally to one surface at a rate of 150g/m? when applied manually, 100g/m? when applied by machine, depending on the substrate. Double sided application is recommended for hard woods.
Open assembly times: Maximum of 4-7 minutes depending on the materials to be bonded. Assembly times are dependant on ambient conditions and substrates used.
Pressing: Pressure must be applied whilst the adhesive is still wet. 0.2 – 0.4 N/mm? for flat bonding, 0.7 – 1.0 N/mm? for laminating and chip board bonding.
