FAQs

1.   Failure to provide adequate adhesive coverage

2.   Failure to apply adequate pressure

We do not recommend bonding to existing laminate or melamine covered surfaces (in fact, our warranty does not cover these applications) because they are non-porous and often prove troublesome. If you decide to try anyway, follow these five guidelines:

1. Sand the entire existing laminate surface with coarse grit sandpaper and then clean the dust off. This creates scratches for the adhesive to grip into.
2. Allow the substrates and the glue to warm up to room temperature before use and perform all bonding at room temperature.
3. Ensure 100% of the area to be bonded is covered with an adequate amount of adhesive (see product label for specific coverage amounts); be especially diligent about coverage around the perimeter.
4. Do not try mating the substrates together too soon. The substrates will be ready to bond when the film of glue on each substrate feels tacky when you firmly press your fingertip onto it. The glue is NOT ready to bond and must dry longer if the glue is still wet or if any glue actually sticks to your fingertip and creates a rubbery “leg” as you pull your finger away.
5. After mating the substrates together, use a hand-held J-roller with as much manual pressure as you can bring to bear over the entire surface. Multiple passes are recommended.

1. Use only a rubber "J" roller. The rubber flexes somewhat and provides pressure on high and low spots on uneven substrates (such as plywood).
2. Use a roller with a width of no more than 3"; rollers of greater width distribute the pressure too greatly over their increased surface area.
3. Use the "J" roller as close to your body as possible. This allows you to bear down and apply greater pressure with your shoulders and upper body. Using a roller with arms extended away from the body does not assure quality bonds.
4. Always roll all edges several times to guard against edge lift.
5. Ensure the "J" roller contacts every square inch of the substrate; missed spots will have only a marginal bond.

Begin with applying the adhesive with a high quality roller cover or brush. Roller covers should have a short to medium nap; brushes should have solvent-resistant bristles. The adhesive should cover 100% of the surfaces to be bonded. When the surfaces are dry enough to bond, they should have a glossy appearance, similar to that of dried, glossy paint. If the dried surface looks flat (non-glossy) like dried flat paint, too little adhesive was applied; a double coat will be necessary. Very porous substrates may require double coating.

For contact adhesives, use this simple test: With clean, dry hands, firmly push your index finger downward onto the adhesive-coated substrate and slowly lift your finger back up. If the adhesive clings to your finger and creates stringy "legs" between your finger and the substrate, the adhesive is still too wet to bond to. If the adhesive is very tacky but does not "leg" as you lift your finger away, it is ready to bond. If the adhesive is not tacky at all, and/or looks flat and dry, it has dried too long; apply another thin coat to reactivate and recheck for tackiness. For WAH20 When ready to bond, surface will be tacky but should not transfer or "leg" to a firmly pressed fingertip. If parts don't stick immediately, they are over-dry and can be reactivated by applying a light coat of fresh adhesive on both parts.

Warmer temperatures will speed drying time and shrink the open time window. Colder temperatures will slow the drying time and will increase the open time window. Very low humidity will shorten the open time; very high humidity in combination with high temperatures can also shorten the open time.

The formation of moisture is called "blushing". Blushing occurs when moisture in the atmosphere condenses on the laminate due to the sudden temperature drop created as the solvents in the glue evaporate. This moisture must be allowed to dry before bonding. Blushing may shorten the adhesive's open time.

The coverage rates found on our product containers and data sheets are theoretical and are presented for the sake of allowing customers to compare one product's coverage against another and to give a rough estimate of the area the product will cover. The theoretical coverage is arrived at using a simple formula:

(Product weight per gallon) / (Product weight required per square foot) = Coverage per gallon

This results in the maximum area that a gallon of product could cover. Any waste incurred in a shop environment (from product overspray, residual product in the spray system, residual product in the container, etc.) will detract from this maximum coverage rate. The more efficiently a shop uses the adhesive, the closer to the theoretical coverage rate it will come.

WA H2O (a water-based contact) and WA 3000, 3001 and 3028 (specially formulated PVA glues) are very good post-forming products with very low VOC and HAP content

Thinning can destroy the chemical balance of the adhesive and voids the warranty.

Adhesives should be stored away from outside walls and should not be in direct contact with concrete floors; both can act as heat sinks and reduce the temperature of the adhesive, thus making it more difficult to use. Caps and lids should be cleaned before replacement and very tightly fitted or screwed to prevent the loss of solvent and the infiltration of air. Rotate stock on a first in/first out basis; adhesive shelf life is one year from date of manufacture, unless otherwise indicated on the product label.

The heat resistance for our WA700A is approximately 200°F, however if this assembly is exposed to direct sunlight for a long period of time, it could delaminate. If the product is used specifically within our standards

The pressure should be set between 40&50 psi, extreme pressure is causing severe squeeze out (no adhesive left to make the bond)

Allergens come from natural rubber and WAH20 is synthetic.

Use fans or heat to accelerate the drying time, make sure to not blow dust onto your unbonded product

Spraying WA800/801 or WA950/951/730/731 would be recommended, but make sure that the metal is cleaned with WA110 or acetone to remove oily film, then used good pressure when ready to make a bond.

Homogenized products benefit the user by not having to stir saving valuable production time. WA830 however does require daily stirring before being used.

It is a marking for mail or shipping in the United States that identifies "Other Regulated Materials-Domestic". Packages bearing this mark contain hazardous material in a limited quantity that presents a limited hazard during transportation, due to its form, quantity, and packaging

The product has been internally tested up to 266°F.

For cleaning wet or dry solvent-based contact adhesives off of spray equipment, for cleaning wet or dry solvent-based contact adhesives off of spray equipment, use WA110 solvent

For cleaning wet or dry solvent-based contact adhesives off of finished goods, use WA121.

For cleaning our PVA products or WA H2O, simply use warm water while product is still wet. Diluted ammonia will aid somewhat in the cleanup of solidified PVA adhesives. WA 121 will be needed to clean dried WA H2O.

VOC stands for volatile organic compound. VOC's are carbon-containing chemicals which contribute to the formation of ground level ozone (smog). HAP stands for hazardous air pollutant. A hazardous air pollutant is one of over 180 specific chemicals identified by the US Government as being detrimental to air quality.

Many local and state governments, and the federal government, have begun to place limits on the amount of VOC and/or HAP certain products can emit. This is especially true around major metropolitan areas. In response, Wilsonart has developed both water-based products as well as low-VOC and low-HAP to help both our customers and the environment.
