SIMALFA 301 is a solvent-free, pressure-sensitive water-based adhesive used for the bonding of foams, upholstery materials, and more. The adhesive has an excellent wet sticking property (instant bond) and high flexibility as well as outstanding heat resistance. The adhesive, depending on the application, is applied to one or both sides using a high volume low-pressure spray gun (HVLP).

Applications & Uses

Application Method
Cleaning

Washable with water

Coverage

Coverage will vary depending on the porosity of substrates and strength of adhesive bond desired. Typical users will cover up to 1000 square feet per gallon. In all cases, user evaluation will be required to determine the optimum coverage levels for their application.

Surface Preparation

Surfaces must be clean, dry and dust free. Any petroleum based product such as oil or grease can prevent suitable bonding.

Application

Never agitate or mix before using. Simalfa can be applied to both surfaces with a spray gun. However, in many instances, single sided application is the preferred method. Hold the spray gun between 4"-8" (1Ocm 20cm from the surface and be sure to overlap the pattern slightly with each pass to ensure unitorm coverage

Assembly and Bonding Time

Simalfa bonds immediately after spraying. Users can reposition the substrates, to maximize the quality of their product, without re-spraying. Pressure may be applied via manual or mechanical methods to enhance the initial bond. In addition, the user can place the substrates together immediately or up to 15 minutes after spraying if required by their production process. After 15 minutes the adhesive may dry and the final adhesion can suffer, or a pseudo-adhesion could take place. The final bond is achieved once the residual water has evaporated. Although water evaporation happens quickly, it is recommended users wait 24 hours before performing any final bond testing.

Application Method and Equipment

SIMALFA is best dispensed via our patented Free Flowing gravity delivery system and applied with our high volume low-pressure (HVLP spray guns. Other spray gun manufacturers may also have suitable application equipment. We can supply all the necessary design, engineering and equipment to properly install and use SIMALFA.
Application Methods:
Manual spray,
Automatic spray, Roll, or Brush
Spray Gun: SIMALFA HVLP
Nozzle Size: 1.5 mm, 2.0 mm or 2.5 mm
Method of Dispensing: Free Flowing System (Patent#: 5868319 or pressure container. Pumping is not recommended
Other Information: All parts coming in contact with adhesive must be made of stainless steel or plastic. Definitely NO colored metals such as aluminum, steel, brass, etc.
Cleaning of Equipment:Use water only. Never use solvents of any type. Do not submerge spray gun in water

Cleanup

In some cases, a wet adhesive may be removed with water. Dry adhesive cannot be removed from porous substrates such as foams or Tabriz. It is recommended that users prevent adhesive from getting on surfaces where it's not wanted.
