Custom chemistry for waterborne epoxy hardener development
Due to restrictions on APEO surfactants, the company were looking to move away from using an APEO-containing waterborne epoxy hardener in one of their flooring products. Ideally, they were looking for an APEO-free hardener that they could use as a ‘drop-in’ but would achieve the same performance as their existing hardener without reformulation. More specifically, they needed a high-gloss hardener that would be compatible with Bisphenol A/F epoxy resins.
The company screened a wide range of commercially available hardeners but none were suitable for their flooring system.
Polyurethane dispersions for high performance exterior PVC coatings
The company had an existing range of waterbased coatings but they contained the hazardous material NMP (N-Methyl-2-pyrrolidone). Replacement of this material with a non-hazardous pyrrolidone alternative without compromising the performance was a priority for the company.
Screening of other commercially available waterbased options hadn’t yielded the results they were looking for. Either they were too high in VOC, too soft or did not coalesce without the addition of extra solvent.
Incozol LV - reactive diluent in 2K PU aircraft coatings
The company had an existing 2K solvent based pigmented polyurethane protective topcoat which was spray applied to military and civil aircraft. The coating had to be durable, provide good weathering properties and chemical resistance.
This system, based on HDI biuret (low viscosity) and polyester/acrylic resin technology, exceeded the required VOC threshold. As a result, the company needed to convert to a VOC compliant coating system to satisfy environmental regulations whilst not compromising any of the existing performance properties.
Incorez 142 - waterborne epoxy curing agent for industrial & decorative coatings
This large multi-national organisation had lost a significant share of the growing market for waterborne epoxy concrete paint. The company planned to re-launch some of its products with the aim of re-establishing its position as a global leader in this market sector.
The remit was to produce a range of market leading decorative and industrial concrete floor paints that exhibit the following characteristics:
- good hardness development
- ability to achieve clean matt and glossy colours
- ease of application
- visible end of pot life
- good in-can stability
- extensive water durability
At the same time the company were in the process of rationalising the number of raw materials in use, so the chosen product had to offer formulation versatility.
Incozol LV - reactive diluent in 2K PU architectural coatings
The company had an existing 2K anti-graffiti, solvent based polyurethane coating which was applied to treated concrete walls (facades) to create special colour effects. The coating had to be durable and exhibit anti-graffiti properties.
This system, however, exceeded the required 500g/litre VOC threshold. As a result, the company needed to convert to a VOC compliant system to satisfy environmental regulations whilst not compromising any of the existing performance properties.
Oxazolidine latent hardeners in PU sealants
The traditional method of curing PU sealants is via the reaction of the terminal isocyanate groups of the polyurethane binder with moisture. This requires a high level of isocyanate content to afford an effective cure which leads to toxicity issues with residual isocyanate monomer. Another problem is the side product, carbon dioxide, produced with this reaction which results in pinholing defects that can then compromise the integrity and aesthetics of the finished coating.
