SPECIFICATION DATA

Physical Appearance : Whitish grey
Ash Content : 0.23%
Moisture Content : 1.5%
Acidity : 7.2

PREPARATION OF GLUE

Liquid UF/MUF Resin : 100 Parts by weight
VISCOEX : 2 to 6 Parts by weight based on resin viscosity
Liquor Ammonia : As per requirement
Hardener : As per requirement
Glue Mix Viscosity : 13-15 sec in B6 cup
pH maintain : 8 to 8.5
Resin Viscosity : 100 Parts by weight

PREPARATION OF GLUE PROCESS

Use horizontal blender type mixer to prepare the glue mix. Take 100 Parts by weight of Resins (PF/UF/MUF) liquid in the mixer and add 2 to 6 Parts by weight VISCOEX and mix it 30 to 45 minutes. The viscosity of the glue in B6 cup should be within the range of 13-15sec.

PREPARATION OF VENEERS FOR BONDING

The surface of the veneer should be smooth, clean and free from dust. The veneers should be flat and uniform thickness. The moisture content of the veneers should be within the range of 6-8%. Higher moisture content increases the risk of blisters and bleed-through, whereas over dried veneers may cause poor face bonding and starved joints.

STORAGE

VISCOEX should be stored in Cool Dry place & away from Direct Sunlight.
