SIAbond D4 is a one part D4 PVA emulsion adhesive, specially formulated for bonding wood. It has a fast set, high bond strength and excellent water resistance. It has a short press time and transparent glue line and can be used for the bonding of windows and doors, for stair bonding, for surface bonding of partitions and parts, bonding of tenon and finger joints, hard and exotic timbers and HPL sheets.
SIAbond D4 can be used with either hot or cold presses. It is easily applied by either brush, roller or serrated glue spreader or by spray. Application tools must be made from stainless steel or plastic.
Application
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.
