Wood Weld Fast Set - 1kg
Construction Chemicals Wood Weld Fast Set is a moisture-curing, single part, polyurethane adhesive, specifically designed for bonding wood to wood very fast. It can also be used to bond many types of plastic foams and other insulating materials to a wide variety of both rigid and flexible facing materials. Such composites form structural sandwich panels and insulated building boards and may be used in the manufacture of cold stores, caravans, mobile homes and offices, insulated building units etc.
SURFACE PREPARATION
Materials to be bonded should be clean and free from dust, grease and other contaminants.
A test panel should always be prepared when new materials are to be used to establish the adhesive’s compatibility.
ADHESIVE APPLICATION
The adhesive can be applied by trowel, notched scraper or polybottle to one surface only of each glue line.
The amount required will vary according to the porosity/smoothness of the substrates and the means of application, but will normally be in the range 80 – 140 grams per square metre.
The panel is then assembled as soon as possible and placed under pressure within 5 minutes.
The pressure required will depend to a great extent on the nature of the substrates but is usually in the range 0.5 to 0.9 bar.
Pressure should be maintained until the adhesive is sufficiently cured to permit handling of the bonded item. Full cure of the adhesive is not obtained for 24 hours and handling within this period should be kept to a minimum.
The open time and cure cycle to permit handling will vary according to:
1. Temperature
2. Weight of adhesive applied
3. Method of working
4. Substrates being bonded
and should always be determined by experiment.

CLEAN DOWN
Construction Chemicals Wood Weld Fast Set when uncured can be removed with cleaning Solvent 6 or
Solvent 9.
Cured product will prove very difficult to remove: however, soaking in Solvent 6 overnight will soften the adhesive.
STORAGE AND HANDLING
Construction Chemicals Wood Weld Fast Set is a moisture-sensitive adhesive and, left in contact with the open atmosphere, will eventually gel. For this reason, Construction Chemicals Wood Weld Fast Set is protected with a blanket of Nitrogen in the container prior to despatch, which forms a dry, inert layer on top of the adhesive.
The above figures do not constitute a specification. They represent typical values obtained for this product.
HEALTH AND SAFETY
Before using this product, ensure that you have been supplied with and have read carefully the following information:
· The hazard label (complying with CPL Regulations 1995) applied to the container
· Construction Chemicals Material Safety Data Sheet for this product
Construction Chemicals Wood Weld Fast Set contains Diphenyl Methane Diisocyanate (MDI) which is harmful if inhaled. Use with adequate ventilation and avoid contact with skin and eyes by wearing suitable protective gear.
The vapour pressure of MDI at 20ºC is low and therefore by normal production techniques like roller coating, spreading or beading, very little diisocyanate vapour will be present in the air.
After contact with the skin, wash immediately with soap and water.
After contact with eyes, irrigate with copious amounts of water and seek medical advice.
