ONE SHOT – A PRE-CATALYZED ADHESIVE SYSTEM

ONE SHOT is a pre-catalysed Amino Plastic Resin for wood-to-wood joinery work. It gives better performance than any other PVAC based adhesives because its heat & moisture resistance property is better than PVAC glue. In some countries, pre-catalysed amino plastic resin is widely used in the panel industry mainly in the solid wood joinery work.

The main concern to use ONE SHOT (Pre-catalysed amino plastic resin) is its shorter Pot Life, which means after mixing this powder with water, it should be consumed within the stipulated time; otherwise the glue will solidify and become useless. To overcome this problem, the glue has to be consumed accordingly. We have a wide range of ONE SHOT products, depending on the working parameters, as required by the customers. One Shot is used in various fields like solid wood-to-wood joinery work, baton joining, plywood repairing, splicing of veneer, Glulam etc. We have also made Low Emission Formaldehyde One Shot for our export market.

Major field of Application of One shot

• Solid wood to wood joinery.
• Bonding of high-pressure laminates, veneers over substrates.
• Splicing of veneers.
• Repairing of plywood.
• Glulam application

  Application Method

• With Spatula
• With manual gluing device
• With glue spreading machines.

According to the final bonding properties and application to serve the different customers we have a wide range of One- Shot products like high Moisture Resistance, Warm water resistance grade as well as Low Formaldehyde Emission grade which are highly appreciated by the customer.

Advantages of One Shot over PVAC glue

• One shot gives better bonding and water resistance property over the commonly used PVAC glue.

• Curing time is much less compared to the PVAC glue; as a result, clamping time of One-Shot bonded panels is almost half the clamping time of the PVAC bonded panels. Hence, productivity can be increased. As it is thermosetting in nature, it is definitely a better choice in terms of heat and moisture resistance.

• One can make the glue according to the required viscosity/solid content

         whatever suits a particular application.

Following points to be taken care of:

• It’s a pre-catalysed thermosetting resin; so it should be kept in cool & dry place.

• If we open the One Shot bag & use partial quantity from it, the bag should be closed tightly so that moisture can not enter into the system

• As it is thermosetting in nature, cured material coming out from the plank joints becomes hard and it creates problem for machining. We must remove the flashing glue from the wood joining surface to avoid the above problem.

• One Shot can be used in high frequency press which gives better bonding & faster productivity.
