Foam coatings

In the case of untreated surfaces of elastic and open-cell polyurethane foams, foreign substances in the form of particles, liquids, air, … penetrate the foam. In the case of a dishwashing sponge in the kitchen, for example, this property is desirable, but it quickly affects its service life. It gets dirty, forms germs and must be disposed of relatively quickly. In comparison, imagine the surface of an orthopedic leg prosthesis, a storage rail in a hospital, or a child’s toy. Here, contamination of the component must not occur under any circumstances. With our seamless and highly elastic foam coating SEETHAN® you protect and refine these surfaces.

You can meet these requirements with SEETHAN®:

• Coating of components with free-form surfaces that cannot be laminated at all with sheeting or only with great effort.
• Seamless surfaces without visible seams, glued joints, …
• Highly elastic surfaces that are as flexible as the foam

Processing

• Processing is carried out by spraying with compressed air paint spray guns. After evaporation of the fast-volatile, organic solvents, a physiologically harmless, highly elastic polyurethane film is formed.
• The drying time depends on the SEETHAN® type, the material application quantity and the drying temperature.
• The degree of air permeability to water repellency of the dried layer depends on the SEETHAN® type and the material application quantity.
• The material is a highly flammable liquid as delivered.
• The technical equipment must be designed to be explosion-proof.
• The notes in the technical information, the processing instructions and the safety data sheet must be observed.

Areas of application

Foam glue

A classic glue / adhesive, usually a different material than the components to be bonded, creates the bond through surface adhesion and its internal strength (cohesion). Our SEETHAN® one-component foam adhesive is the same material as the polyurethane foam and fuses the components to be bonded instead of just gluing them together. This creates a 100% bond between the two foam parts.

These requirements can be met with SEETHAN® foam adhesive:

• Bonding of components with free-form surfaces that cannot be bonded at all with sheet material or only with great effort.
• With low material application, in contrast to an adhesive film or a classic adhesive, the bonded joint is as elastic as the foam itself.
• Elongation capacity up to 750 %
• Temperature application range from -30 °C to 100 °C

Processing

• Processing can be carried out by spraying with compressed air paint spray guns or by brushing with a brush. After evaporation of the fast-volatile, organic solvents, a physiologically harmless, highly elastic adhesive layer is formed.
• The open time depends on the quantity applied. The thinner the adhesive is applied, the shorter the open time. The extension of the open time can be additionally controlled with a retarder.
• The drying time depends on the quantity applied and the component geometry. The thinner the adhesive is applied and the smaller, the shorter the drying time. The freshly bonded components should dry overnight to allow the organic solvents to evaporate completely.
• Only components made of flexible polyurethane foam can be bonded.
• The material is a highly flammable liquid when delivered.
• The technical equipment must be designed to be explosion-proof.
• Variant: The components can first be coated with our SEETHAN® foam coating and then bonded directly. This gives you maximum freedom in terms of geometry.
