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.
Oxazolidine moisture scavengers
Wind turbines, particularly offshore installations, are exposed to hostile environments which demand that the coatings systems must be able to withstand these conditions for the lifetime of the turbine, typically 20 to 25 years. Difficulties related to access makes coating maintenance expensive as well as technically challenging for offshore wind turbines and lifetime should therefore be of primary concern when specifying coatings.
Key characteristics of the final coatings are:
- They must be able to withstand UV and heat radiation
- They must be able to withstand a high degree of weathering erosion including salt water resistance
- They must be tough and durable yet flexible enough to withstand impacts without chipping
Incozol 4 - latent curing agent for 1K waterproofing balcony coatings
Balconies and walkways like all other parts of a property require maintenance. Most of these balconies and walkways consist of concrete elements where, for a lack of efficient protection, water can penetrate causing structural weakness and leading to leaks, stalactite formations and the delamination of paint on the underside of the balconies.
As a result, the company wanted to develop a range of balcony systems specifically designed to protect balconies against the challenges presented by the elements.
The main functional requirements of the coatings were:
- One component - for ease of use
- Crack bridging capabilities
- Elastomeric – allowing for thermal movement
- Hard wearing
- Seamless technology – no seams or joints
- Water vapour permeable
- UV resistance and resistance to yellowing
Oxazolidines in polyurethane coatings for wind turbines
Traditional polyurethane based coatings require tin based catalysts to help speed up the cure as the coating film takes a long time to set and can lead to water spotting during storage. Faster curing polyaspartic topcoat technology has a propensity to dry spray in high humidity and shop conditions have to be adjusted accordingly.
The company was aiming to develop a polyurethane top coat with fast cure and suitable working time across a spectrum of application conditions. The polyurethane top coat had to conform to the current VOC regulations (420g/l) and provide the specified chemical, UV and weathering resistance. The final coating was to be applied to glass fibre plastic on the blades of wind turbines.
