Products in Flexible Packaging Adhesives: Polyurethanes (PU)

AEROSIL® R 202 is a hydrophobic fumed silica grade, treated with a polydimethylsiloxane. This product can be used in defoamer formulations for sedimentation stabilization and due to its high hydrophobicity as defoaming component.

AEROSIL® 200 is a hydrophilic fumed silica with a specific surface area of 200 m²/g.

AEROSIL® R 972 is hydrophobic fumed silica grade treated with DDS (Dichlordimethylsilane). The moderate hydrophobicity of these AEROSIL® products is suited for defoaming properties in the presence of appropriate hydrophobic liquids. They are recomended for improving the sedimentation stability of defoamer dispersions as well.

SYLVARES TP 2040 tackifier is a thermoplastic terpene phenolic resin designed for tackifying hot melt adhesives to provide superior adhesion and thermal-stability properties.

SYLVARES TP 2040HM tackifier is a high softening point thermoplastic terpene phenolic resin designed for tackifying hot melt adhesives to provide superior adhesion and thermal-stability properties.

Defoamer for water-based coating systems, silicone free. SCHWEGO foam 8013 is a highly effective defoamer suitable for water- based systems and adhesives especially for those based on polyurethane and acrylate.

Velsiflex® 328 is a blend of dipropylene glycol and diethylene glycol dibenzoate in an approximately equal ratio. Velsiflex 328 is primarily known for its exceptional performance in polyvinyl acetate adhesives. It displays excellent wet tack, set times and open time performance. It also improves adhesion to acrylic latex caulks and is a high-solvating PVC plastisol.

Velsiflex® 342 S is a blend of dipropylene glycol dibenzoate and other benzoate esters. It is a lower moisture / lower hydroxyl plasticizer. It has been widely used in 2K polyurethane systems to reduce cure interface, which also provides better rebound, improved tear strength and reduced swell with solvents. It is also used in many polysulfide sealant applications and has proven to be a very efficient ester from a softening agent perspective.

Velsiflex® 342 is one of the most popular liquid plasticizers. It is a high-solvating plasticizer containing mostly dipropylene glycol dibenzoate. It is used in a wide variety of applications, including caulk, adhesives, resilient flooring, PVC-coated fabrics and artificial-leather cloth. In PVC, it acts as a medium- viscosity high solvator that saves energy and improves process ability. Vinyl applications using Velsiflex 342 have excellent resistance to extraction from solvents and oils. It also works with vinyl to make it UV – light-degradation resistant and stain resistant.

SYLVARES TP 300 tackifier is a thermoplastic terpene phenolic resin designed for tackifying hot melt adhesives to provide superior adhesion and thermal-stability properties. This resin can be used in low temperature applications.

Kolon Industries HIKOREZ® A-1100 is a pale yellow thermoplastic resin obtained from the polymerization of C5 aliphatic olefin and diolefin generated in the thermal-cracking process of naphtha. This resin provides well-balanced adhesion properties such as adhesive strength, bond strength and cohesive force required for pressure sensitive adhesive (PSA), and is mainly used as tackifier and hot melt adhesive (HMA) for pressure sensitive adhesive. This resin also can be used as the binder for hot melt road marking (HMRM). .
