PolyVinyl Acetate (PVA) (white)
PolyVinyl
Acetate (PVA) (yellow)
Contact
Hot-melt
Applications
glue smallbullet ideal for bonding melamine-faced cabinet parts and for gluing cross-grain solid-wood assemblies where wood movement is likely;
glue smallbullet can be coloured with dyes etc.
glue smallbullet low grade (craft or hobby glue);
glue smallbullet edge- and face-gluing, bonding structural joints;
glue smallbullet bonding plastic laminates etc;
glue smallbullet can be coloured with dyes etc.
glue smallbullet high grade (professional/ industrial glue);
glue smallbullet edge- and face-gluing, bonding structural joints;
glue smallbullet bonding plastic laminates etc;
glue smallbullet can be coloured with dyes etc.
glue smallbullet bonding plastic laminates;
glue smallbullet decorative overlays;
glue smallbullet other rigid sheet materials;
glue smallbullet some modern water-based cements are fast drying and give high performance;
glue smallbullet applying significant pressure to the work greatly increases the strength of the bond.
glue smallbullet hot-melt glues and guns are available with high, low or dual melt-point glue;
glue smallbullet high-melt systems widely available/used;
glue smallbullet low-melt systems are safer and less likely to harm the materials being glued;
glue smallbullet hot melt is useful for edge-banding sheet material and for the rapid assembly of temporary fixtures.
Availability/ using
glue smallbullet ready to use glue smallbullet ready to use;
glue smallbullet water can be added up to 5% to increase working time.
glue smallbullet ready to use;
glue smallbullet water can be added up to 5% to increase working time.
glue smallbullet ready to use glue smallbullet supplied in solid sticks;
glue smallbullet must be applied hot;
glue smallbullet low-melt glue shouldn't be applied with a high-melt gun.
Typical working time
#
10 to 15 min 5 to 30 min 5 to 30 min dry prior to assembly;
open drying times:
10 to 20 min (water based),
2 to 15 min (solvent based),
5 to 30 sec,
longer if parts preheated
Clamp time #
1/2 to 2 hrs 20 to 90 min 20 to 90 min 1 to 5 min will increase bond strength No clamping needed; firmly press parts together as quickly as possible
