IM-300Melamine Urea Formaldehyde Resin is a liquid state thermosettingMelamine Urea Formaldehyde resin which meets all the requirements for aType I Adhesive.
It is recommended for manufacture of ofparticleboard, plywood, veneering, and other kinds of wood working forexterior usewhich is resistant to high humidity. This resin isspecifically designedfor 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

SUITABLE FILLER AND HARDENER

Werecommend to use wheat flour filler of about 17-25 part by weight ofthe resin. For hardener, we recommend IWH-200 hardener, a specialhardener for use with IM-300 Melamine Urea Formaldehyde Resin, of about0.3-1.0 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
Water0-4 parts by weight

MIXING PROCEDURE

Theabove recommended formulation is best mixed through the followingprocedure.

  1. First pour all of the IM-300 Melamine Urea Formaldehyde Resinand all of the wheat flour while mixing.
  2. If the viscosity is too high, asmall amount of water can added to the mix.
  3. Finally pour theIMH-200hardener and mix until a homogenous glue mix of desiredviscosity isobtained.

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°C25°C30°C
35°C
Gel time / pot life11 hours
8 hours5 hours3 hours

VENEER PREPARATION

Preparationmust be done to the veneers to be glued. The veneers must have asmooth and clean surface, free of dust, glue stains, etc. Avoid usinghardwoods since IM-300 Melamine Urea Formaldehyde Resin is applied toplywood that must have a very high standard of bonding strength.Moisture content of face and back veneers must be controlled at below12%.

GLUE SPREAD

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

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

Assemblytime on panels must be as short as possible. If the process isretarded by factory conditions, the usage of hardeners must beadjusted, 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°C125°C
Basic time
1.9 minutes1.8 minutes1.4 minutes1.0 minutes

Additionalpress time is required according to the distance to the Farthest GlueLine (FGL), as the panel gets thicker, the longer press time itrequires. The additional time (minutes/mm) is as follows;
