PVA ADHESIVE WOOD BONDING BEST PRACTICE<br />

PVA “D” Grade - D Stands for Durability<br />

PVA wood glues are usually described and classified according to their resistance to water as determined by European<br />

Standard EN204. This equates to four durability or “D” grades of PVA with the following applications:<br />

INTERIOR ONLY<br />

SUITABLE FOR<br />

D1 Wood moisture content is less than 15% Interior areas, where the temperature only occasionally<br />

exceeds 50°C for a short time and the moisture<br />

content of the wood is less than15%<br />

D2 Occasional short-term exposure to running or condensed<br />

water and high humidity<br />

Interior construction<br />

Furniture construction<br />

D3<br />

D4<br />

Frequent short-term exposure to running or condensed<br />

water and heavy exposure to high humidity<br />

*Exterior water not exposed to weather<br />

Frequent long term exposure to running or condensed<br />

water.<br />

Exterior exposed to weather, when protected by an<br />

adequate surface coating.<br />

Interior construction<br />

Furniture manufacture<br />

Window frames<br />

Window frames<br />

Outdoor furniture<br />

The best results will only be achieved, if the correct grade of PVA adhesive is selected for the application.<br />

SURFACE PREPARATION<br />

Surface preparation is as important as adhesive selection. A good bond requires that a thin layer of PVA adhesive<br />

is applied to a surface which is free of a) Plane skipped, torn, crushed, chipped or loose wood fibres, b) Foreign<br />

matter such as, oil, grease, grit and dust.<br />

Wood surface should be bonded within 24hours of cutting or dressing, in order to reduce the risk of surface oxidation<br />

or moisture variation.<br />

Knife cut surfaces as produced by planers and routers, give the best bonding surfaces. These tools leave a smooth<br />

open grain, enhancing the adhesive penetration into the wood surface fibres, producing a strong bond.<br />

Sawn surfaces give a good bonding medium, although the cut is rougher than those produced by planes or routers<br />

it is still satisfactory for structural and non-structural joints.<br />

Blunt saw, plane and router blades will tend to crush the wood fibres. This will reduce the ability of the PVA adhesive<br />

to penetrate the wood surfaces fibres and will ultimately reduce the quality of the bond. Cutting edges should<br />

be kept sharp.<br />

Typically<br />

150 g/m 2 when manually applied to one surface<br />

100g/m 2 when machine applied to one surface.<br />

Double sided application is usually recommended for hard woods.<br />

Typical 5 to 40 minutes<br />

Very dependent on ambient temperature and substrate moisture content<br />

Softwood typically 8-10bar (125-150 PSI)<br />

Hardwood typically 12-17bar (175-250 PSI)<br />

Density of wood being bonded dictates the pressure required. Too much<br />

pressure can drive the adhesive into the wood, reducing bond quality.<br />

Too little pressure will not ensure close enough contact between substrates<br />

reducing bond quality.<br />

Press times are dependent on adhesive coat weight and substrate<br />

Typical figures are:<br />

Hot Press (Decorative laminate/plywood) 50°C/8mins<br />

Cold Press (Decorative laminate/plywood) 20°C/20mins<br />

Can also be used in a Radio frequency curing press (RF)<br />

Equipment can be cleaned with warm or cold water whilst the adhesive<br />

is still wet.<br />

BOND TROUBLESHOOTING<br />

Common bonding problems and solutions are detailed below<br />

Defect Cause Solution<br />

Open Glue Joint • High or low wood moisture content<br />

• Joint surface too rough<br />

• Excessive or insufficient adhesive<br />

• Adhesive cured before construction<br />

• Insufficient pressing time<br />

• Excessive or insufficient pressure on joint<br />

Sunken Joint • Bonded panel machined to soon after<br />

construction<br />

Follow recommended parameters for<br />

each type of joint to be bonded.<br />

Leave panel 16 to 24 hours after pressing,<br />

before machine<br />

Telegraphing • Non-uniform adhesive coating Accentuated through thin faced or high<br />

gloss finish laminates<br />

Visible Glue Line • Non-uniform edge machining Reduce quantity of adhesive on joint<br />

Blistering (No adhesion<br />

between layers)<br />

• Skips in adhesive spreading<br />

• Pre-curing or pre-drying of glue line<br />

• Surface inactivation or oily wood<br />

Assemble joints immediately after adhesive<br />

application.<br />

Reduce the quantity of adhesive.<br />

Follow recommended parameters<br />

for each type of joint to be bonded.<br />

Prepare surface with fine grade sand<br />

paper or clean surface with organic<br />

solvent e.g. Alcohol<br />

Panel Warping • Construction imbalance Check thickness, density, moisture, species<br />

of components and their compatibility<br />

Component Thickness<br />

Variation<br />

• Component moisture variation Equalise component moisture content<br />

before assembly.<br />

Würth Web Spray Adhesives must be stored at optimum temperatures, ranging from 15-35°C.<br />

Caution: Keep away from direct sunlight. Do not stand on a cold concrete floor.<br />

Step 2:<br />

Always use Würth Web Spray products with suitable accessories<br />

Step 3:<br />

Carefully perform setup process:<br />

1. Ensure the gun is fitted with the correct spray tip<br />

2. Connect hose and gun to the canister<br />

3. Open canister valve<br />

Step 4:<br />

For the ideal spray, hold the spray gun at a 90° angle to the surface approximately 4-6” away. Spray in long,<br />

steady strokes releasing trigger with each change of direction, ensuring the spray pattern is overlapped by about<br />

1”. TIP: Always give the edge a second coat, and it is best to coat the edges first to ensure a double coat.<br />

Step 5:<br />

Würth Web Spray Adhesive products are contact adhesives, ensure that both surfaces have been covered<br />

achieving a 100% (20-30grams per square meter) coverage for best results.<br />

Step 6:<br />

Allow Würth Web Spray Adhesive to take up to 2 minutes before bonding, protect from contaminates such as dust<br />

and moisture. Adhesive on each surface should be dry and nontransferable to touch.<br />

Step 7:<br />

Use a J Roller to eliminate air pockets.<br />

Step 8:<br />

Use a solvent cleaner to remove any overspray.<br />

AFTER USE:<br />

A) Do not turn off the valve or disconnect the hose if the canister still contains glue. For best results, leave the canister<br />

in a ready-to-spray position for the next application.<br />

B) Once your Würth Web Spray Canister is empty:<br />

• Turn off the adhesive canister valve<br />

• Bleed the hose of excess adhesive<br />

• Dispose off the empty canister as per product label instructions<br />

TROUBLE SHOOTING:<br />

1. Gun will not spray: Is the valve turned on? Gun turned on? Blockage in gun?<br />

Strip down and clean all parts in solvent cleaner.<br />

When setting up a new system which includes a new tank, hose and gun it is advisable to run the hose and gun<br />

without a tip initially to avoid blocking it. Only until the adhesive is seen to be coming through the gun and only<br />

on new systems. If difficulties are encountered getting a new canister started always remove the spray tip FIRST to<br />

check if adhesive is coming through the gun. Clean the tip and replace.<br />

Gun sprays but a heavy weight of adhesives?<br />

Has the canister been subjected to low temperatures? Bring the canister up to room temperature. Turn it upside<br />

down and shake to agitate.<br />

Blockage in hose? Gun and hose should be connected to a canister at all times. Failure to do so will result in the<br />

adhesive drying in the hose and gun causing blockages.<br />

2. Adhesive Failure? Würth Web Spray Adhesives are contact adhesives that work by bonding to themselves. It<br />

is necessary for adhesive to be on both surfaces.<br />

Before making the assumption that the adhesive has failed, it is important to consider the following points:<br />

• Is there adhesive on both surfaces?<br />

• Is there enough adhesive? 80-100% coverage of both surfaces?<br />

• Were the substrates cold? Enough to produce “Bloom”?<br />

• Was the canister or its environment cold? Cold canister will spray more gas and less adhesive giving low adhesive<br />

coat weights.<br />

• Was sufficient pressure applied to the piece to bring the two surfaces together? Würth Web Spray is a contact<br />

adhesive and the adhesive must make contact to itself to form the bond. Large areas left open with low coat<br />

weights are particularly susceptible to this problem.<br />

• Were they suitable substrates? Whilst Würth Web Spray Adhesives will bond a wide variety of materials it is<br />

important to test the substrate to ensure the product will work on your particular application.<br />

3. Laminates Problems: Laminate zips off. Usually a result of a combination of insufficient adhesive being applied<br />

and insufficient pressure applied during assembly. Dust contamination is another consideration .<br />

Blisters. When assembled the piece looked fine but subsequently blisters appear. Often the results of insufficient<br />

adhesives applied to one or both surfaces combined with insufficient pressure applied to the piece. Remember<br />

adhesive should give 80-100% coverage to both surfaces. If the substrates are very absorbent a second coat is<br />

required. Also if the substrates are impermeable it is possible to trap solvent inside which may also cause blistering.<br />

4. Heat Resistance: Whilst Würth Web Spray Adhesives have a high level of heat resistance (up to 100°C) they<br />

are not recommended for use on light boxes, radiator covers and other areas where a high level of heat resistance<br />

is required.<br />
