Carpet rolls

GENIOSIL^® Silane-Modified Polymers

Parquet or general wood-floor adhesives based on SMPs now represent more than 50% of the European wood-floor adhesive market due to their outstanding performance, ease of use and environmentally friendly properties. GENIOSIL^® SMP parquet adhesives display the necessary movement capability, since wood remains a natural product, which expands and contracts depending on the prevailing temperatures. Despite this, the adhesive meets industry-standard adhesion profile and performance requirements. Furthermore, such adhesives contain no solvents or toxic components and can therefore be supplied without hazard labeling and packaging. Rapid through-curing allows sanding after only 24 hours.

Benefits:

Easy to apply
Easy removal of excess adhesive without staining
Solvent free

Applications:

Wood-flooring adhesive

VINNAPAS^® Solid Resins

VINNAPAS^® solid resins are used as binders for solvent-based wood-flooring adhesives.

Benefits:

Excellent solubility in mild solvents
Low odor
Excellent adhesion to wood

Applications:

Wood-flooring adhesives

HDK^® Pyrogenic Silica

HDK^® pyrogenic silica find application as rheology additives in parquet adhesives. Hydrophobic HDK^® is used in modern STP-E systems as well as in polyurethane-based adhesives to improve processability, sag resistance and storage stability.

Benefits:

Improved processability
Improved sag resistance
Increased shelf life

Applications:

STP-E systems
Polyurethane-based adhesive

Manufactured Housing

VINNAPAS^® Vinyl Acetate-Ethylene (VAE) Polymer Dispersions

VINNAPAS^® VAE polymer dispersions play a significant role in almost every aspect of manufactured housing. They are ideal for a wide variety of applications.

Benefits:

Excellent formulation compatibility
Long-lasting, highly durable bonding
Strong adhesion to various substrates
Outstanding workability

Applications:

Sub-floor installation
Wall bonding and lamination
Product assembly

GENIOSIL^® Silane-Modified Polymers

GENIOSIL^® silane-modified polymers are found as the base polymer for adhesives in dry-wall assembly where high strength is needed and subsequent paintability is a must. As dry-wall paneling becomes increasingly employed in residential buildings, with the replacement of mechanical fastening by chemical bonding, it is essential to choose an adhesive that offers high performance with no toxic emissions.

Benefits:

Adhesion to diverse substrates
Paintability of sealed joints

Applications:

Drywall panels

VINNAPAS^® Solid Resins

VINNAPAS^® solid resins are used as binders for various solvent based mastic construction adhesives, e.g. sub-floor and landscaping adhesives. They adhere excellently to numerous substrates, such as wood, glass, stone, metal and many plastics. They are ideal binders for the formulation of VOC-compliant adhesives for the US market as they can be formulated with acetone, methyl acetate and t-butyl acetate which are classified as exempt solvents from the regulatory definition of VOC by The United States Environmental Protection Agency (EPA).

Benefits:

Excellent solubility in mild solvents
Low odor
Excellent adhesion to numerous substrates

Applications:

Mastic construction adhesives, e.g.
Sub-floor adhesives
Landscaping adhesive

Building Components

During manufacturing of the foam, the EPS beats are treated with fire-retardant agents.

VINNAPAS^® Vinyl Acetate-Ethylene (VAE) Polymer Dispersions

In the manufacture of fire-retardant EPS (expanded polystyrene) foam, VINNAPAS^® vinyl acetate-ethylene (VAE) polymer dispersions serve as a binder for good adhesion of the functional coating to the particles and of the particles among each other. They are especially effective, as VAE exhibits inherently lower flammability than comparable technologies and shows very good compatibility with general ingredients for flame-retardant formulations, such as phenol, melamine, borax, aluminum hydroxide, magnesium hydroxide, carbon black or expandable graphite. The fire-retardant EPS foam can be used in the manufacture of aluminum structural insulated panels.

Benefits:

Cost-effective and easy to process
Exceptional dimensional stability of EPS board after curing
Excellent bonding between EPS particles
Good water resistance and non-slip properties
Excellent tack properties
Very good compatibility with widely used flame-retardant additives
Significantly reduced flammability of EPS sandwich panels

Applications:

Panels
Insulation facing film

HDK^® Pyrogenic Silica

Chemical dowels based on free-radical curing systems and 2K epoxy systems can be efficiently rendered thixotropic by the addition of HDK^® products. Hydrophobic grades are particularly effective at producing thixotropic effects, and are chemically inert in reactive resin systems, so that the rheological properties of the formulations remain unchanged over the typical storage times.
