PUR Easy 250 Adhesive Applicator
and moisture curing polyurethane adhesives combine the
benefits of a hot melt system with structural strength bonds.
Adhesive is dispensed from a hand held applicator at 121°C
providing time to align parts before the adhesive quickly
cools, giving rapid handling strength up to 1000psi within
minutes. The 100% solids, low VOC formulation eliminates
the need for drying and ventilation equipment.
Ideal Markets
• Furniture
• Kitchens/ Joinery
• Boat Building
Benefits
• Fast assembly
• Rapid strength build-up
• Thin bond lines
• Door Manufacturing
• General Manufacturing
For furniture and upholstery, PUR
adhesive bonds leather or fabric
gimping and seams.
Bond wood components throughout
a spa enclosure. Durable bond
resists temperature differentials,
weathering moisture and chemicals.
With a thin bond line, PUR adhesive
makes a secure, aesthetically-
pleasing crown moulding assembly.

Open Time
Set Time
This is the maximum time between the application of the adhesive and when the
parts must be joined together. This information is based on 1/8” bead and non-
metallic substrates at 75
o
F (20
o
C).
Also known as fixturing/clamping time. This is the minimum amount of time
required for the adhesive to solidify and hold the parts together (able to support a
tensile load of 5 psi).
