ADDIGUP® AW is an additive based on few-layers graphene GUP® specifically designed to provide superior physical and mechanical properties to water-borne paints and coatings while retaining mechanical properties, minimally impacting the rheological properties of the host material and without a significant increase in viscosity.

RESULTS OF ANTI-CORROSION TEST
WATER BASED Acrylic formulation – ADDIGUP® AW
Test: neutral salt spray – creep assessment
After 2500 hours the formulation with ADDIGUP® AW reports a 82% reduction in corrosion creep compared to the same formulation without graphene.
ENHANCED DURABILITY WITH ADDIGUP® AW
WATER BASED Acrylic coating – ADDIGUP® AW
Adding a concentration of ADDIGUP® AW of 6 wt% the hardness of the coating increases of almost 2 times

PROCESSING GUIDELINES & ADDITION RATE
ADDIGUP® AW is added to the host material to be processed. The recommended loading rate of ADDIGUP® AW is in the range 3-10 wt% calculated on the weight of the host material. The optimum dosage level should be determined with specific test based on the required performance, host matrix characteristics, processing conditions and presence of other fillers. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
ADDIGUP® AW is used in all formulations that require superior corrosion protection and thermal dispersion on high tech applications with extensive warranties. The best results are achieved for systems with DFT > 50 mm. Can be use in a wide variety of resin systems. Combinations with other active anti-corrosive pigments is possible and may be advantageous in specific cases maximizing the potential creating a synergistic effect with graphene. For example, due to its high electrical conductivity GUP® creates a synergistic effect with zinc (in the formulation where is present), improving its cathodic safeguarding behavior.
ADDIGUP® AW can require adjustment of the existing formulation.
