This product must be used at workshop temperature between 15 and 30°C.

Catalyze: between 1 and 2 % of MEKP 50, according to the requested thickness and production cycle.

Material bonding on laminate

The surface must be free from any contamination and should not be coated with paraffin. All organic coating such as epoxy, polyurethane or alkyd paints should be removed completely.

The laminate must be minimum in gel.
Prepare and add the catalyst.
The catalyst revelator enables to check the quality of the mixing.

Depending of the storage time and temperature, the gel time can change. In that case it is possible to increase the catalyst level up to 3%.

Application with spatula, pastry bag and suitable bonding machines.

We do not recommend application with less than 10°C ( air and surface temperature )

Please contact us for further information.


Product should be kept away from direct sunshine and at temperature below 20°C. Under these conditions, the product will keep its properties 4 months from production date.
