For manufacturers that utilize flat-rolled steel, aluminum and other metals to fabricate parts or products, the ability to bond decorative foils and laminate films to the substrate provides an opportunity to deliver attractive finishes for a competitive edge.<\/p>

Decorative finishes include the look of stainless steel, brushed copper, and wood grains, as well as a variety of colors, imprints, and gloss grades. Laminate films can also serve a functional purpose by providing scratch or chemical resistance.<\/p>

However, the process of laminating to metals is fraught with potential complications. If the wrong adhesive is utilized, if the curing process is not precisely controlled or a variety of other variables are not managed, the result can be a high scrap rate or parts that fail in the field.<\/p>

When this occurs, OEMs and even the coil processors that supply them with bare or B-stage (pre-applied adhesive) coil turn to custom formulators for unique solutions to production issues.<\/p>

In many cases, the proper adhesive formulation can have significant benefits such as speeding\u00a0production, eliminating scrap, reducing the amount of material required and even improving corrosion, UV and antimicrobial resistance.<\/span><\/p>

Options for applying laminate<\/b><\/p>

The use of laminate applied to metal to fabricate parts or products is widespread throughout manufacturing. Some of the more common applications including appliances (refrigerators and freezers, washing machines, dishwashers, microwaves, range or fume hoods), construction products (insulated wall panels, garage doors, roofing products) and the mobile and manufactured home markets (walls, door panels).<\/p>

The processing of adhering laminates to coils of metal or sheets occurs in several different ways.<\/p>

Manufacturers can employ in-house personnel to spray or brush adhesives within the plant. However, this process is slow, requires manual labor and brings up safety and environmental concerns. Quality can also be an issue and scrap rates are frequently quite high.<\/p>

Automated equipment can also be used to apply foils and films to flat-rolled metals that come with pre-applied B-stage adhesive from a coil processor. This type of adhesive is designed to activate and cure within a specific temperature range. The laminate is then applied to the coil at the manufacturer\u2019s plant using furnaces and nip rollers.<\/p>

Although automated processing is much faster and more efficient, it can also lead to quality control issues due to temperature variances within the curing ovens involved. In some cases, scrap rates can be as high as 20%.<\/p>

\u201cApplication of adhesives in the final manufacturing facility can lead to significant amounts of scrap, higher per piece labor costs, and can expose the manufacturer to significant environmental costs and scrutiny,\u201d says Eric Fossen, managing director of Spencer Ridge Consulting of Ontario, Canada. \u201cSo they often are looking for a more efficient solution that gives them a more consistent [laminate] performance.\u201d<\/p>

Fossen, who serves as a consultant to the coil processing industry, says the simplest solution for OEMs is often to outsource the process completely. This eliminates the need for in-house labor, application equipment, curing ovens, and environmental control facilities.<\/p>

Adhesives applied in a coil coating operation offer the advantage of a high degree of consistency in both film thickness and cure conditions, which can provide a stronger and more durable adhesive bond. High quality application allows the final product to be post-lamination formed into many severe bends and shapes without affecting the integrity of the bond between adhesive and film.<\/p>

Adhesive Quality<\/b><\/p>

Although coil processors control the application process much more tightly, the quality of the bond ultimately depends on the type of adhesive used.<\/p>

According to Fossen, many adhesive manufacturers offer a variety of off-the-shelf options, but will not customize a product to meet a customer\u2019s unique requirements unless very large volumes are involved.<\/p>

\u201cWith large adhesive suppliers, if they have a product that works \u2013 great. If not, they are often not willing to tweak the product to make it work for a specific application,\u201d says Fossen.<\/p>

When this occurs, coil processors and even OEMs turn to custom adhesive formulators with the expertise and experience in coil processing to come up with unique solutions to solve difficult problems.<\/p>

Case in point \u2013 Door Panels<\/b><\/p>

For Elixir Door Company, manufacturing entrance doors for manufactured homes involved vinyl-coated steel that was stamped and formed before being filled with urethane foam for insulation and structural strength.<\/p>

To accomplish this, Elixir Door ordered coil-rolled steel with pre-applied B-stage adhesive. The vinyl was then applied using curing ovens and nip rollers at the manufacturing plant.<\/p>

Approximately 2-3 years ago, however, the company began to experience significant adhesion problems leading to a high scrap rate.<\/p>

\u201cThe vinyl was coming off in major proportions \u2013 not just a \u2018spot here\u2019 or a \u2018spot there,\u2019 but in many places. It was very inconsistent,\u201d explains general manager Archie Brown.<\/p>

Unable to identify the reason, Brown says he called in a custom adhesives and coating formulator, Universal Chemicals & Coatings (Unichem). The company specializes in coil processing and can create custom\u00a0adhesives and also coatings.<\/span><\/p>

The solution involved an adjustment to the temperature parameters of the curing oven as well as a custom-formulated adhesive from Unichem designed to cure within a broader temperature range.<\/p>

\u201cUnichem analyzed our entire process and came up with some corrective actions,\u201d says Brown. \u201cWe adjusted everything and have had no problems since.\u201d<\/p>

According to Brown, Elixir Door subsequently decided to outsource the entire process. Now the coil processor delivers a finished, vinyl-coated part using Unichem\u2019s adhesive formulation that is already sized and stamped into shape.<\/p>

\u201cWe were paying [the coil processor] to apply adhesive, then paying to apply the vinyl in house. Now they do it all in one operation at their facility,\u201d says Brown. \u201cSo our cost is much less and we don\u2019t have to worry about scrap because it\u2019s on them, not us anymore.\u201d<\/p>

Case in Point \u2013 Roofing plates<\/b><\/p>

Unichem has also developed a B-stage adhesive used for bonding metal plates to PVC membranes. The plates are fastened to the roof deck and later heat activated to bond to the membrane, creating a permanent and highly water-resistant roof.<\/p>

The B-stage adhesive is initially applied to metal substrates using a continuous coil coating line. The adhesive coated coils are later stamped into the finished plates.<\/p>

To create the ideal adhesive, Unichem had to meet a large number of physical performance criteria, such as resistance to exterior exposure, fast activation cycle and high initial and aged bond strength.<\/p>

Black-to-white<\/b><\/p>

According to Fossen, even minor formulation changes can improve the end product. He cites the example of one customer that wanted to utilize the same adhesive, but change it from black to white so that it would not show through if the laminate film was scratched in the field.<\/p>

Unichem was able to not only create a white adhesive, but also expanded the curing temperature range as well.<\/p>

\u201cUnichem is unique in being able to take a set of performance criteria and formulate an adhesive to meet the requirements,\u201d adds Fossen.<\/p>
