WATERBORNE RED PRIMER based on NEOCRYL XK801 WITH ASCONIUM-143

This is a formulation for a waterborne red primer, specified to be used with NEOCRYL XK801 and ASCONIUM-143. The steps detail the addition of various raw materials in a specific order to create the primer. Here's a breakdown of the key components and steps:

1. Step 1 (Mill-Base):
   • Function: This step involves adding several raw materials to the mill-base tank with good agitation and then setting aside the mixture.
   • Raw Materials:
     • WATER: Solvent
     • EDAPLAN 490: Dispersing Agent
     • BYK 024: Defoamer
     • AMP90: Neutralizer
     • Dowanol DPnB: Co-Solvent
     • BAYFERROX 130M: Iron Oxide Pigment
     • DURCAL 5: Calcium Carbonate
   • Purpose: These components are dispersed with high shear rate for 10-15 minutes to ensure thorough mixing.
2. NEOCRYL XK801 WITH ASCONIUM-143:
   • Reference: WBACRY8730R
   • Guiding Formulation: Waterborne Red Primer
   • Salt-Spray Performances: CRS (Buiged 2313); 250 hours; 1 layer; 65-70 µm dry
3. Step 2 (Premix):
   • Function: Prepare a premix and set it aside for later use.
   • Components: ASCONIUM-143 (Anticorrosion Additive) and AMP90 (Neutralizer)
4. Step 3 (Let-Down Tank):
   • Function: Add components to the let-down tank in order with continuous stirring.
   • Components:
     • NEOCRYL XK801: Binder
     • STEP-2 PREMIX: Premix prepared in Step 2
     • BYK 024 (Defoamer), WATER, TAFIGEL PUR64 (Thickener), Dowanol DPnB (Co-Solvent), ASCOTRAN-H10 (Antiflash-rust Additive)
   • Purpose: These components are progressively added to create the final mixture.

This formulation is intended to provide corrosion protection as a primer for various substrates, as indicated by the salt-spray performance testing.
