Soyad™ Adhesive Technology

Soyad adhesive technology is a patented, bio-based, formaldehyde-free adhesive system used to produce environmentally friendly hardwood plywood and engineered wood flooring.

Soyad adhesives are water-based systems formulated with natural soy flour and a proprietary crosslinking resin. When blended together, the resin reacts with the protein in the soy flour to form a durable, water-resistant thermoset adhesive that is comparable in strength and performance to urea-formaldehyde-based adhesives.

Soyad adhesives provide a number of performance advantages for manufacturers of engineered wood products. Consider the following:

  • An industry-proven adhesive with 70-90% bio-based content
  • Eliminates formaldehyde-related health hazards for workers and consumers
  • The strength provided compares to other no-added-formaldehyde (NAF) technologies and traditional formaldehyde-based adhesive systems
  • Existing application equipment can be used to easily transition from a formaldehyde-based adhesive
  • Eligible for CARB Phase 2 exemptions
  • Qualifies for LEED points

Industry Acceptance

Soyad adhesives help meet the growing demand for bio-based products and are the adhesive system of choice for manufacturers that want to comply with formaldehyde regulations and help improve indoor air quality. Over 150 million hardwood plywood panels have been produced globally with Soyad adhesives, making it the leading NAF adhesive for hardwood plywood in the world.

Ease of Use

Soyad adhesives are applied using the same type of application equipment used for traditional hardwood plywood and engineered wood flooring. Dosage rates, press temperatures and press times are similar to those of urea-formaldehyde-based adhesives, so production parameters do not typically need to be altered.

Formaldehyde Emission Standards

Engineered wood products made with Soyad adhesives meet all global formaldehyde emission standards, including CARB Phase 2, European E0 and Japanese F**** standards. These products are also CARB Phase 2 exempt and are eligible for LEED points for improved indoor air quality.
