Columbia Innovations is proud to offer the latest breakthrough in adhesive technology by Hercules. By combining proprietary resin chemistry with a natural, renewable resource, Soyad® adhesives provide a cost-competitive, environmentally-friendly alternative for today’s demanding interior wood products market.
Based on soy flour and containing absolutely no formaldehyde, Soyad® adhesives are quickly becoming the system of choice for industry leading manufacturers who want to stay ahead of regulations and help improve the quality of indoor air for their workers and customers.
Designed for the manufacture of decorative plywood, particleboard, MDF, and engineered wood flooring, Soyad® adhesives offer a number of advantages:
In addition, Columbia Innovations offers consultation services and technical support for adhesive systems in the forest products industry.
Soyad® Case Histories
Commercial applications confirm that Soyad® adhesive systems are cost-competitive, environmentally-friendly alternatives to traditional wood adhesives. The following case histories highlight some of the key benefits that Soyad® adhesives offer manufacturers of interior wood products.
Soyad® Adhesive Allows Particleboard Manufacturer to Eliminate Formaldehyde From Its Boards
To comply with new formaldehyde emissions standards, a North American particleboard manufacturer replaced its existing urea formaldehyde-based adhesive system with a Soyad® adhesive system from Hercules. Because Soyad® adhesives contains no formaldehyde, it use has allowed the manufacturer to reduce formaldehyde from its press and the makeup of its boards. In fact, the boards far exceed CARB Phase 2 emission standards, U.S. Federal HUD emission standards, and European E-1 emission standards, making them particularly well-suited for homes,, hospitals, and institutions nationwide.
Plywood Manufacturer Significantly Reduces Formaldehyde Emissions By Switching to Soyad® Adhesive
A North American decorative hardwood plywood manufacturer wanted to reduce the formaldehyde emissions of its panels to a level meeting CARB Phase 2 emission standards. Hercules recommended that the manufacturer replace its existing urea formaldehyde-based adhesive system with a Soyad® adhesive system. Upon converting to the Soyad® adhesive, formaldehyde emissions were reduced to meet CARB 2 standards, which allowed the panels to qualify for LEED® points.

Formaldehyde Free The Soyad adhesive system is a combination of a proprietary resin and a natural, renewable resource giving the customer the assurance that the products they are manufacturing do not contain any additional formaldehyde.
LEED® Compliant Products properly manufactured with the Soyad adhesive system are LEED compliant and may contribute points for EQ Credit 4.4 for Low-Emitting Materials: Composite Wood.
CARB Phase II Ready Products properly manufactured with the Soyad adhesive system will meet or exceed the new California Air Resource Board Phase I and Phase II standards for formaldehyde emissions.
Adhesive Cost The Soyad adhesive system is cost competitive with other UF alternative adhesives such as PF, MUF, pMDI, and PVAc through a combination of actual glue costs and processing time.
Pot Life The shelf life of the components that make-up the Soyad adhesive system exceeds 60 days. The pot life of the mix itself can still be utilized up to 24 hours giving the customer the comfort in knowing that their delivery system will run smoothly.
Cure Speed and Temperature The Soyad adhesive system takes slightly longer to cure at comparable temperatures of a traditional UF system. As compared to other adhesive alternatives, customers should be pleased with their productivity in using the new Soyad adhesive technology.
Water Resistance Composite panels and interior hardwood plywood can withstand the rigorous boil test without falling apart like a UF system.
Color Color of the glue lines or the composite panel has always been an area of concern. The Soyad adhesive is very light in color and allows the true color of the wood to show unlike some of the alternative adhesives. This is a critical characteristic in many end-user applications.
Sprayable The Soyad adhesive system is a perfect fit for the customer who requires their adhesive to be sprayed into their blenders. The mixed adhesive typically runs below 500 centipoise which will be a excellent viscosity for most spraying applications.
Handling and Clean-up Most adhesive manufacturers only concentrate on the actual performance characteristics of their adhesives, but the Soyad adhesive system has to be the easiest, most environmentally friendly system to handle and clean up. Because there are no harmful constituents in the mix, most municipalities will allow the wash water to be simply put down the drain. The Soyad adhesive does not stick to machine parts and hoses like other systems. Simply wash it off with warm water.
