IM-300 Melamine Urea Formaldehyde Resin
IM-300 Melamine Urea Formaldehyde Resin is a liquid state thermosetting Melamine Urea Formaldehyde resin which meets all the requirements for a Type I Adhesive.
 
It is recommended for manufacture of of particleboard, plywood, veneering, and other kinds of wood working for exterior use which is resistant to high humidity. This resin is specifically designed for use in manufacturing operations on the Asian market.
 

TECHNICAL SPECIFICATIONS

   *Note: Specifications can also be adjusted upon customer request.


 

STANDARDS

IM-300 Melamine Urea Formaldehyde Resin complies to the following international standards;

 UK standard
 : BS-1455 types BR 
 USA standard 
 : C-35-36 types Technical and types I
 German standard 
 : DIN 16705 type AW 100, A 100
 Japan standard
 : JPIC types I

SUITABLE FILLER AND HARDENER

We recommend to use wheat flour filler of about 17-25 part by weight of the resin. For hardener, we recommend IWH-200 hardener, a special hardener for use with IM-300 Melamine Urea Formaldehyde Resin, of about 0.3-1.0 parts by weight.

 

RECOMMENDED MIXING FORMULATION

IM-300 Melamine Urea Formaldehyde Resin will achieve best performance if it is being formulated with the following composition;

 IM-300 Melamine Urea Formaldehyde Resin 
 : 100 parts by weight 
 Industrial grade wheat flour as filler
 : 17-25 parts by weight 
 IMH-200 hardener
 : 0.2-0.4 parts by weight 
 Water : 0-4 parts by weight

 

MIXING PROCEDURE

The above recommended formulation is best mixed through the following procedure.

  1. First pour all of the IM-300 Melamine Urea Formaldehyde Resin and all of the wheat flour while mixing.
  2. If the viscosity is too high, a small amount of water can added to the mix.
  3. Finally pour the IMH-200 hardener and mix until a homogenous glue mix of desired viscosity is obtained.

 

POT LIFE OF THE RECOMMENDED GLUE MIX

The formulation above will have a pot life varying depending on environment or room temperature, as follows;

 Room temperature 
 20°C  25°C   30°C 
 35°C 
 Gel time / pot life 11 hours
 8 hours 5 hours 3 hours

 

VENEER PREPARATION

Preparation must be done to the veneers to be glued. The veneers must have a smooth and clean surface, free of dust, glue stains, etc. Avoid using hardwoods since IM-300 Melamine Urea Formaldehyde Resin is applied to plywood that must have a very high standard of bonding strength. Moisture content of face and back veneers must be controlled at below 12%.

 

GLUE SPREAD

The usage of IM-300 Melamine Urea Formaldehyde Resin should employ double glue line, of about 30-32 g/sqft for thinner cores and about 35-40 g/sqft for thicker cores.

 

PRE-PRESSURE

The normal pressure is 9-10 kg/cm2 and the cold press time is about 15-30 minutes, adjustable according to factory conditions.

 

PANEL ASSEMBLY TIME

Assembly time on panels must be as short as possible. If the process is retarded by factory conditions, the usage of hardeners must be adjusted, that is to be decreased a little bit.

 

HOT PRESS

HOT PRESS TIME

The basic hot press time is calculated by room temperature, which is as the following;

 Room temperature
 110°C 
 115°C 
 120°C   125°C 
 Basic time
 1.9 minutes 1.8 minutes 1.4 minutes 1.0 minutes

Additional press time is required according to the distance to the Farthest Glue Line (FGL), as the panel gets thicker, the longer press time it requires. The additional time (minutes/mm) is as follows;

 Distance to the FGL Press plate temperature 
 110°C 
 110°C 
 110°C 
 110°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

Example: a 3-ply panel with 2 mm inner core and 1 mm face and back veneers, and the FGL is 1.0 mm. The required press time at 120°C is as follows;

 Heat transfer time  
=
 1.0 minute x 1.0 mm 
=
 1.0 minute 
 Basic setting time 
= = 1.4 minutes  + 
 Total pressing time 
= =
 2.4 minutes

The hot press time to be adjusted by experience according to the factory working condition

 

HOT PRESS PRESSURE

The optimum pressure on hot pressing of IM-200 Melamine Urea Formaldehyde Resin is about 9-10 kg/cm2.

 

CLEANING AND HANDLING

IM-300 Melamine Urea Formaldehyde Resin is easy to handle and washable with warm water. The Formaldehyde smell is relatively less than that of other Formaldehyde glue. This resin's reactivity is high, therefore it should be stored in a cold place.
