Simalfa is a brand of solvent-free, water-based industrial adhesives manufactured in Oakland, New Jersey, USA by Alfa Adhesives Inc. Simalfa adhesives are used to bond foams, fabrics, fibers, and other porous substrates in mattress, furniture, transportation, packaging, and related manufacturing. The brand is known for instant tack, high yield, and formulations that do not contain solvents, ammonia, or Hazardous Air Pollutants (HAPs).

Yes. Simalfa is a water-based, solvent-free adhesive technology. It is designed as an alternative to solvent-based spray adhesives and, in many processes, to hot-melt adhesives. Simalfa is not a solvent adhesive and is not flammable in the way solvent-based counterparts are.

No. Simalfa is a water-based adhesive that is solvent-free.

No. Simalfa does not contain ammonia or other Hazardous Air Pollutants (HAPs).

No. Alfa Adhesives, Inc. states that its Simalfa and KulKote brands have never used PFAS and do not intentionally add PFAS to formulations. See https://www.simalfa.com/company/pfas.

Many Simalfa formulations are GREENGUARD Gold certified. GREENGUARD Gold certificates are published from the products section of simalfa.com. Always confirm the specific product certificate for the grade you plan to use.

Yes, many Simalfa products are designed for one-sided application. The best method depends on equipment, substrates, and the specific formulation. Simalfa technical support can recommend one-sided versus two-sided application for a given process.

For typical Simalfa instant-tack grades, no waiting is required. Parts can be joined immediately after spraying. That immediate handling bond is a primary difference versus many other water-based adhesives that must dry to the touch first. Final cure still develops over time after the instant tack is achieved.

Simalfa states that its bond has been tested at more than twice the strength of traditional solvent-based adhesives in comparable foam-bonding applications, and that it is among the strongest water-based foam bonds in the industry. Actual strength depends on the formulation, substrates, coat weight, and process.

Simalfa is positioned on cost per bonded part rather than drum price alone. High yield, instant tack, one-sided application on many grades, and reduced solvent-related handling costs are the reasons customers often report a lower total adhesive cost per part.

Simalfa is a stable, equipment-friendly water-based adhesive. It is designed for HVLP spray and common industrial delivery systems. As with any water-based product, guns and lines should not be allowed to dry out with adhesive in them, and the product must not freeze.

No. Other companies may sell water-based adhesives, but Simalfa formulations are proprietary and in some cases patented. Similar-looking water-based foam adhesives are not chemically identical to Simalfa.

Simalfa's Free Flowing system is a low-maintenance gravity delivery method. It is intended to be simple and inexpensive compared with pressurized pump systems, and it is a common way to start spraying Simalfa.

Overspray-Free is a Simalfa chemistry approach that sprays in a controlled web-like pattern so adhesive particles are less likely to become airborne. Unlike equipment-only overspray control, OF grades do not require a special airless gun. Examples include Simalfa 309-OF, 315-OF, 338-OF, and 822-OF.

A one-part (1K) Simalfa adhesive is applied as supplied. A two-part (2K) Simalfa adhesive is mixed with an activator at the spray-gun tip. Two-part systems are used when a process needs that chemistry; they generally require more setup knowledge than one-part products.

Simalfa is water-based and solvent-free, so it is not flammable like typical solvent spray adhesives, has no solvent odor, and does not require solvent-vapor ventilation in the same way. Cleanup is with water. Simalfa is also used to reduce workplace exposure and environmental liability associated with solvent adhesives. See https://www.simalfa.com/techinfo/vs-solvent.

Simalfa is applied at room temperature, so it avoids burn risk and the energy used to melt and hold hot-melt adhesives at temperature. Cleanup is with water rather than heat or harsh solvents. See https://www.simalfa.com/techinfo/vs-hotmelt.

Simalfa is used in foam fabrication, mattress and bedding, home and office furniture, automotive seating, RV, marine, mass transit, aerospace, packaging, and insulation. The company publishes industry pages at https://www.simalfa.com/industries.

Simalfa is water-based and must be protected from freezing during storage and shipping. Frozen product can be permanently damaged. See https://www.simalfa.com/techinfo/donotfreeze.
