Edging Counters with 3mm PVC best practices?

1/11/13

We are realizing a greater demand to provide counters with 3mm PVC edgeband applied. We have had great success using our edgebander to adhere 3mm to straight counters, however, radius counters and "L" shaped counters require us to hand band. We have seen some adhesion failure (10%) in these instances, and wanted to know if anyone could recommend a proven adhesive and or process that can minimize such failure. We are looking into many variables, shop temperature, adhesive types, methodology, and discussing our challenges with a variety of pvc vendors. Any and all suggestions are greatly appreciated.

What are you using now for adhesive that results in 10% failure? We have used melamine glue with good results.

I second Melamine (Roo glue) never had a failure with pvc.

If you are using contact cement don't use solvent type. It doesn't get along with the plasticizers in the PVC. We recently got a portable hand held glue pot bander. It actually works fairly well for those large curvy things that we can't' handle on the other banders. Slow and we haven't mastered not getting glue in the wrong places. We changed the glue to the same as used in our stationary contour bander. We prime the panel edges before banding to improve adhesion. These things might even be a solution for a one man shop that does very limited banding. Can be bench mounted and used for straight line work.

We warm our edgeband before we apply it. Usually about 110-120 degrees. If you get it too hot, it will expand and then shrink when it cools. We sometimes apply 3mm to 90 degree angles with a 1" radius. In those cases we also WARM up the edges of the particle board about 2" from every corner. That seems to help the adhesive soak into the wood better. You could also try roughing up the back of the edgeband with some sandpaper. It would be a little time consuming but it would help the glue adhere to the edgeband.

Plastisizers used in the PVC edge band actively migrate into EVA and PVA adhesives reducing adhesive strength, PU and melamine base are delivering better resistance.

Are you using banding made for contouring? Much more flexible! I don't know if that flexibility comes from additional plasticizers that may cause other problems though.
GT, I wonder how long it takes for EVA to fail on PVC? We've got banding here in the shop that was done 20 years ago, no failures! I'm assuming it was done with EVA since that is/was the most common.

FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
