Typical Characteristics

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 solventbased epoxy coatingsPolyamide has been designed to overcome those difficulties which exist with older type organowax rheology modifiers eg seeding falsebody 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

0215 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 5C 41F and 30C 86F 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 highspeed dispersers is ideal for the incorporation and activation of Polyamide in that they develop both the necessary level of shear andtemperaturePolyamide 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 65C 113  149F but more preferably from 55  65C 131 149F and maintaining this condition of dispersion and temperature for 20  30 minutesThe activation process constitutes the conversion of the Polyamide particles to an interacting network of fibrelike particles It is this network that gives rise to the final coatings 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 applicationImmediately following application where low shear conditions again predominate the coatings 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 very good levelling and sag resistance
