IP-100 Phenol Formaldehyde Resin
IP-100 Phenol Formaldehyde Resin is a thermosetting liquid Phenol Formaldehyde resin, which meets all the requirements for a WBP (Water Boil Proof) type adhesive.
 
The adhesive produces a water-resistant bond and is recommended for use in the manufacture of marine plywood, block board, bagasse board, and other wooden products for exterior use with high humidity and moisture.

SUITABLE FILLER AND HARDENER

In preparing the glue mix, IP-100 Phenol Formaldehyde Resin must be mixed with IPH-100 hardener and water. IPH-100 hardener is a mix of hardener and special filler, in packages of 40 kg. Besides that, a small number of other suitable fillers can be added to adjust the viscosity according to factory requirements.

 

RECOMMENDED FORMULATION

For maximum product performance, it's recommended that IP-100 Phenol Formaldehyde Resin is mixed according to the following formulation;

 IP-100 Phenol Formaldehyde Resin
: 100 parts by weight
 IPH-100 Hardener
: 15-30parts by weight
 Water: 0-5 parts by weight

 

MIXING PROCEDURE

The above recommended formulation needs to be mixed according to certain steps to guarantee maximum gel time. The steps are as follows;

  1. First pour all of the required IP-100 Phenol Formaldehyde Resin
  2. Then pour in the IPH-100 hardener
  3. Mix the two for about 5 minute
  4. Last add more water and mix for 5-10 minutes more. The glue mix is then ready.

 

GEL TIME OF THE RECOMMENDED FORMULATION

The above recommended formulation will have a gel time that varies according to room temperature, which is as follows;

 Room temperature
 20°C 25°C 30°C 35°C
 Gel time
 11 hours
 9 hours
 8 hours
 4 hours

 

VENEER PREPARATION

Before applying IP-100 Phenol Formaldehyde Resin, the veneers' surfaces must be prepared to be clean and free of dust and other things. The veneers' moisture content must also be controlled at maximum of 10% for both veneers and cores.

 

GLUE SPREAD

IP-100 Phenol Formaldehyde Resin application with single glue line uses about 160-200 g/m2 of glue, while a glue spread with double glue line uses 32-40g/sqft. Glue spread is adjusted according to thickness. Thicker veneers need more glue spread due to having rough surface.

 

PRE-PRESS

Normal pressure for pre-press is 9-10 kg/cm2, and being done for about 15-20 minutes, which is adjustable to the working conditions of the factory.

 

PANEL ASSEMBLY

Generally panel assembly must be done with time as short as possible, and the glue mix must still be viscous when hot pressing is applied. A dry glue mix will decrease the panel quality.

 

HOT PRESS - HOT PRESS TIME

Hot press process on IP-100 Phenol Formaldehyde Resin application is best done under the following conditions;

 Temperature : 135 ± 5°C
 Pressure : 10 kg/cm2

The above conditions will result in hot press time as follows;

 Thickness
 Time (min-max)
 Below 6 mm (3-ply)
 45-50 seconds/mm
  9 mm (5-ply)
 50-55 seconds/mm
  12 mm (5-ply)
 45-50 seconds/mm
  15 mm (7-ply)
 50-55 seconds/mm
  28 mm (11-ply)
 55-65 seconds/mm

 

HOT PRESS - HOT PRESS PRESSURE

Optimal pressure for hot press is 9-10 kg/cm2. Hot press is adjusted to wood thickness and factory working conditions.

 

CLEANING AND HANDLING

Mixing and spreading equipments must be cleaned before the glue leftover cures. This can be done easily with water. But if the glue has dried, it can be peeled off easily.

IP-100 Phenol Formaldehyde Resin is alkali in nature of chemical reactions. When the surface of the resin liquid touches air, it will form a thin layer.

Contact with the skin must be washed off with water. IP-100 Phenol Formaldehyde Resin is soluble in water easily, in any proportions.
