TrimBonder from ITW Devcon

PVC trim has gained market share in residential applications since its introduction several years ago. Today, several companies are capitalizing on its popularity, among them ITW Devcon with its TrimBonder product.

In the July issue of Qualified Remodeler, we introduced you to the company’s TrimBonder nail hole filler kit. This GreenGuard certified product allows contractors to permanently fill nail holes or gaps in CPVC trim boards without the need for sanding. The kit includes a lightweight 50-ml applicator, four nozzles and two 50-ml cartridges. The easy-to-use cartridge and mix nozzle allows woodworkers to quickly and precisely fill nail holes with less waste and enables faster turnarounds.

ITW Devcon has been in business for 59 years and makes epoxy, urethane and acrylic adhesives and sealants. One of its strategies is to identify niche markets and develop products to satisfy the needs in those markets. That was the case when the PVC trimboard market exploded in 2003 and 2004. Not only were contractors looking for ways to fill nail holes and gaps, they wanted a way to laminate the boards for applications requiring greater thickness.

“Most of manufacturers can only extrude PVC products up to an inch because they get very porous,” says Dave Bongiorni, business manager of specialty products for ITW Devcon. Carpenters therefore needed to laminate the board into thicker dimensions for custom crown mouldings or window surround treatments. ITW Devcon created an adhesive that allowed them to do that and also could be used for filling holes and gaps.

Bongiorni says the only similar product is a water-based adhesive that uses a dauber brush to apply the product to a board which then is squeezed together and nailed in place. Water can be attracted to the bond area, and it can take up to 48 hours to cure, he says. Even though it’s nailed, the boards can shift before the bond has cured.

TrimBonder, on the other hand, comes in a caulking cartridge and dries in about 15 minutes. The cartridge has two-chambers and a mixing nozzle, unlike the one-part system employed by other products.

Currently ITW Devcon is fine-tuning other ideas for TrimBonder and is in the process of launching TrimBonder HB for custom and millwork shops. Because cut edges of cellular PVC appear unfinished, this product fills in those edges and can be sanded with fine sandpaper to create a smooth finish like the skin of the PVC. This makes the piece look as though it has been molded rather than cut and also keeps the PVC from absorbing paint.
