Description
Polyamide is a pure polyamide especially recommended in 2K epoxy primers for its robustness. Polyamide is a micronised amide wax rheology modifier offering very good recoatability for ambient curing solvent-based epoxy coatings.Polyamide has been designed to overcome those difficulties which exist with older type organo-wax rheology modifiers e.g. seeding, false-body and migration of readily dissolved species to the surface. Consequently, when used in strong solvent systems, coatings formulated using Polyamide offer an enhanced performance and very good recoatability.
Recommended addition level
0.2-1.5% under heat and shear
Standard Packaging
Other packaging may be available upon request- 15 Kg Bag
Handling & Storage
It should be stored in the original containers in a dry place at temperatures between 5°C (41°F) and 30°C (86°F). Avoid exposure to direct sunlight or frost. In these conditions, this product should be used within 48 months from delivery.
Processing instructions
The use of high-speed dispersers is ideal for the incorporation and activation of Polyamide in that they develop both the necessary level of shear andtemperature.Polyamide is best added along with the initial charge of resin during the pigment dispersion and grind stage. Efficient activation will be achieved by allowing the temperature during dispersion to rise to 45 – 65°C (113 – 149°F), but more preferably from 55 – 65°C (131 -149°F), and maintaining this condition of dispersion and temperature for 20 – 30 minutes.The activation process constitutes the conversion of the Polyamide particles to an interacting network of fibre-like particles. It is this network that gives rise to the final coating’s shear thinning rheology. This shear thinning characteristic provides a very high viscosity under the low shear rates associated with sedimentation, and a low viscosity at the much higher application shear rates. The net result is excellent control of sedimentation combined with ease of application.Immediately following application, where low shear conditions again predominate, the coating’s viscosity undergoes a time dependent recovery as the network reestablishes itself. This time dependence is known as thixotropy and enables the final coating to attain verygood levelling and sag resistance.
