High bonding strength
Ideal for the assembly, joint and area bonding applications
The size of our product start from (200MG,900G,3.5KG,10KG,25KG,50KG,and 125KG)
SCOPE OF USE:
For assembly bonding applications (dowel, tongue and groove, mortise and tenor joints)
For joints (solid wood, edge banding etc.)
Large surface area bonding, HPL boards, hardboard etc.
1 – Material preparation:
Work pieces should be clean and a tight fit. Woods with high oil or tannin content,
such as teak, should be wiped off with acetone before applying the glue.
Wood moisture content should be between 12 and 8%.Higher moisture content increases final setting time
2 – Glue application:
Apply Ponal Lacquer and Varnish Glue to one surface with a brush,
plastic comb (Ponal adhesive comb),
Glue roller, or glue application device. With hard woods glue must be applied to both surfaces.
Do not use tools that contain iron(risk of discoloration)
3 – Application temperature:
Do not apply below 5 °C.
4 – Clamping pressure:
surface bonding> 0.2 N/mm2
assembly bonding and hard woods> 0.5 N/mm2
work pieces under tension generally required higher clamping pressure.
5 – Pressing:
Pressing can either be hot or cold with the usually tools, appliances or presses.
6 – Clamping time:
Clamping time depends on the ambient conditions, wood type and moisture content and the amount of
glue applied. Under normal conditions minimum clamping time is:
bonding wood approx. 60-90 minutes at 20°C
approx. 45-60 minutes at 30°C
bonding HPL board approx.120 minutes at 20 °C
approx. 90 minutes at 40 °C
approx. 45 minutes at 60 °C
With hot pressing work pieces can be further worked after they have cooled.
7 – Wood discolouration:
The pH of Ponal is 3.5. With oil or tannin containing woods discoloration is unlikely if no iron-containing
tools are used during glue application. Wood discoloration can be removed with a 2-3 % aqueous oxalic acid solution.
8 – Open time:
Open time depends on room temperature, relative humidity, wood hardness and moisture content and the
amount of glue applied. At a room temperature of 20°C.open time is a maximum of 8 minutes. Locate
work pieces while the glue is still wet.
