Nitrile adhesives, also known as acrylonitrile-butadiene rubber (NBR) adhesives, are widely used in various industrial adhesive bonding processes due to their unique properties and capabilities. Nitriles offer several advantages that make them suitable for challenging environmental conditions where other polymer based adhesive formulations might fail. Let’s take a brief look at these performance properties and...
Since its first use by ancient Maya civilisations, rubber is still an essential polymer for hundreds of everyday products including vehicle tyres, footwear, clothing, sports equipment and kitchen appliances. It is also critical to many industrial and commercial applications such as electrical insulation, PPE, seals and gaskets, hydraulics, rubber drive belts, roof coatings and-yes, you’ve...
Silicones are synthetic polymers that can take many forms including solids, rubbers, liquids, gels, oils and pastes. They have an extremely wide range of physical and chemical properties due to their inorganic silicone-oxygen molecular structure. This makes them quite different to organic carbon-based substances in terms of greater chemical stability and inertness, providing silicones with...
Specialist adhesives consist of a variety of chemistries and come in a range of forms to suit specific requirements. Choosing the right adhesive formulation for a particular problem or application involves careful consideration of a number of factors. These include: Bonding properties of the adhesive The application and substrate type Application methods and production requirements...
Colour is a marketing differential that has significant branding importance for a company’s product range. Whether it’s the practically minded olive drab, or a favourite shade of lavender, the importance of consistency is paramount when designing performance coatings for end use applications. Consider a newly painted room. The perceived difference between a white and an off-white...
In 1902, and long before polyurethane adhesives and coatings were known of, ITAC’s founder John Marcus, discovered tyre scrapings dissolved in solvent made an excellent rubber adhesive. When painted on to the outside carcass of a tyre, this formed an ideal primer coat to which the tyre tread could be bonded. This marked ITAC’s beginnings...
Specialist coatings play a critical role in satisfying the requirements of an ever-increasing number of industrial and commercial products and systems. The coating’s end application and intended use determines the effects it should impart in order to provide the desired performance. This clearly has a direct influence on their formulation design. Therefore, for specialist coatings...
ITAC employ a variety of testing methods to develop adhesive coating products that align with their customer’s application requirements. This area of work ensures reliability and uniformity in the bonding process within parameters that may also influence performance including consistency of raw materials, application substrates, environmental conditions, and joint design. The results of these...
Welcome to part two of our summary of adhesive coating testing methods used at ITAC. We explained in part one that the tests we perform and results we provide are a critical element of our work. These enable our customers to choose the best adhesive or coating system for a specific application, and to help...
Itac employ a variety of testing methods to develop adhesive coating products that align with our customer’s application requirements. These include: Adhesive bond strength test (tensile, shear, peel), Heat seal testing, Drawdown testing, Fire retardancy testing, Colour testing Viscosity testing (Brookfield), Solids testing, Surface conductivity testing. Details of the testing standards that Itac work to...
