MFP 134 Powder Resin is a neat Melamine Formaldehyde Resin, specially manufactured in powder form for plywood industry. It only requires mixing with water, filler (wheat flour) and catalyst prior to use. In the cured state, MFP 134 is a cross linked, insoluble infusible material.

| American Standard | : CS-35, Type Technical & Type I |
RECOMMENDED FORMULATION
Type I (Reguler)
| MFP 134 | : 100 parts by weight |
| Water | : 60 – 70 parts by weight * |
| Filler | : 20 – 30 parts by weight |
| HDPIW 120 | : 0.5 – 1.0 parts by weight * |
Type I (B 3/4)
| MFP 134 | : 100 parts by weight |
| Water | : 50 – 60 parts by weight * |
| Catcher
Filler |
: 25 – 30 parts by weight
: 15 – 25 parts by weight |
| HDPIW 120 | : 1.5 – 2.5 parts by weight * |
MIXING PROCEDURE
The above formulation should be mixed according to certain steps as follows:
- First pour recommended amount of water into the mixer, followed by MFP 134
- Start the mixer
- Add catcher to the mixer, followed by filler, and mix continuously
- Add HDPIW 120 then mix 3-5 minutes
- Mixing is now ready to use
GLUE SPREAD
The following schedule may be used a guide only:
| Core Thickness | Glue Spread (Double GL) | |
| g/sqft | ||
| Below 1.8 mm | 26 – 32 | |
| 2.1 – 2.5 mm | 30 – 36 | |
| 3.2 – 3.8 mm | 34 – 40 | |
| 4.2 – 5.0 mm | 36 – 42 | |
PRE-PRESS
- Time: 30 – 40 minutes
- Pressure: 8 – 10 kg/cm2
ASSEMBLY TIME
- Open Assembly Time
For optimum results in bonding strength, it is recommended that open assembly time should not exceed 30 minutes.
- Closed Assembly Time
For optimum results in bonding strength, this time should be kept to minimum, preferably less than 30 minutes.
HOT PRESSING – LOADING TIME
This is the time period elapsing between placement of the first panel assembly in the press and the application of full pressure to the whole press load. To avoid any risk of pre-curing, loading time should be kept as short as possible, preferably no more than 2 minutes. The glue must still be tacky, hence capable of flow prior to application of full pressure.
HOT PRESSING – PRESSING TEMPERATURE AND TIME
| Press Temperature | 110°C | 115°C | 120°C 125°C |
| Basic Setting Time (minutes) | 1.9 | 1.8 | 1.4 1.0 |
The basic hot press time is calculated by temperature as shown by above table. Additional pressing is required according to the farthest glue line as thicker the panel, the longer time it requires.
| Distance to Deepest Glue Line | Temperature of Press Plate | ||
| 110°C | 115°C | 120°C 125°C | |
| Below 5 mm | 1.2 | 1.1 | 1.0 0.9 |
| 5 – 10 mm | 1.4 | 1.3 | 1.2 1.1 |
| Over 10 mm | 1.6 | 1.5 | 1.4 1.3 |
Note: Do not use higher hot press temperature to attain shorter pressing time period unless the veneers’ moisture content are carefully controlled. Always remove panels as soon as the press opens,
The recommended core veneer moisture content is minimum 6%, optimum 8 – 10% and maximum 14%.
STORAGE, CLEANING AND HANDLING
Reactivity of MFP 134 is relatively high, thus should be kept away from direct heat and sunlight.
PACKAGING & SHIPPING
MFP 134 is packed in 25kg WWP bag with double polythylene liner and double heat seal. A unit of 20ft container should contain up 20 MT.
