K-Flex 850S is a blend of diethylene glycol dibenzoate and dipropylene glycol dibenzoate.
The composition of this blend of classic dibenzoates is optimized for waterborne latex applications.
In particular, the K-Flex 850S dibenzoate plasticizer blend is designed for:
-Latex adhesives
-Latex coatings
-Latex caulks and sealants
-Latex overprint varnish and waterborne flexographic ink
Like K-Flex DP and 500, K-Flex 850S has full FDA approvals for adhesives and was created to maximize on efficiency and cost effectiveness.
In coatings K-Flex 850S is low in VOC to assist the formulator on issues of VOC reduction.
Also, K-Flex 850S is considered a low vapor pressure-volatile organic compound (LVP-VOC) by Rule 310 of CARB.
This means that K-Flex 850S is not considered a VOC in California for applications such as latex caulk.
K-Flex 850S is not recommended for PVC applications; however, it can be used in other applications such as polysulphide sealants.
In the EU K-Flex 850S is label-free.
K-FLEX 850S is economical to use and tailored to provide good handling and excellent compatibility in waterborne systems.
K-FLEX 850S is highly recommended for direct-to-metal coatings such as primers, interior and exterior latex paints, floor polishes, and industrial and protective coatings.
K-FLEX 850S is also effective in nitrocellulosic and acrylic lacquers.
K-FLEX plasticizers have become standard plasticizers for adhesive products.
They improve the processability of many polar polymers used in water-based latex and hot-melt adhesives.
They further lower the glass transition temperature of the binder and thus enhance its adhesiveness.
K-FLEX plasticizers are mainly used in protective coatings such as underbody protection and seam sealers.
They are more effective at gelling PVC than common standard plasticizers.
As a result, they allow shorter cycle times or lower processing temperatures, making production more efficient.
In paints and coatings, K-FLEX dibenzoates are excellent at increasing film-formation, even at lower temperatures.
This means that polymers become solid at a certain temperature and no longer flow together, which impairs film-formation.
Plasticizers ensure that this temperature, the so-called minimum film formation temperature, can be reduced.
Thus, these products can even be processed at room temperature.
K-FLEX dibenzoates are the go-to alternative to volatile solvents.
The K-FLEX line of low-volatile coalescing agents is highly compatible with the typical polymeric binders used in these applications, such as acrylates, vinyl and styrene acrylates, polyvinyl acetate and ethylene vinyl acetate.
K-FLEX coalescing agents help produce paints and coatings with a superior surface appearance and high durability.
In order to create a paper surface that could be used in packaging, for example, additives are needed.
They enhance the coating process and improve the resulting products.
K-FLEX products for coating paper and cardboard are safe for use in packaging with food contact.
K-FLEX products provide optimum performance in sealants and joint compounds.
This includes articles based on polyacrylates, polyvinyl acetate, their copolymers and silane-terminated sealants.
For reactive polyurethane applications, low hydroxyl dibenzoates have been developed to ensure consistency in the production of shelf-stable sealants.
In polysulfide sealants, the dibenzoates serve as an alternative to phthalates, which have been used up to now.
K-FLEX dibenzoates are known for their excellent gelling properties in a wide range of polymers, including PVC.
As additional plasticizers, they can supplement moderately-gelling standard plasticizers.
In both cases, this results in lower processing temperatures and/or shorter processing times.
The flexible PVC products produced show better stain resistance and create high wear-proof surfaces.
Typical applications are floor and wall coverings, artificial leather and gloves.
Nail care and depilatory waxes are just some of the personal care products that our additives are used for.
Personal care is one field where our products with a low ecological footprint are truly appreciated: K-FLEX delivers the non-phthalate products that customers demand.
K-FLEX 850S is a very effective, low VOC plasticizer for hot melt adhesives and pastes as well as water-based adhesives.
