Polyurethane Enamel 8800 Series,
Hi Solids, Low VOC, Mil-PRF-85285
Product Description
8800 series Polyurethane Enamel is a high solids, low voc, 2 component system
designed to meet the requirements of Mil-PRF-85285.
Intended Use
For high quality, air dry finishes (or force dry)
Good acid, alkali and solvent resistance, including jet fuels and hydraulic
fluids
Excellent toughness, flexibility, abrasion and impact resistance
Excellent dry time and catalyzed pot life
Use: from light duty industrial applications to heavy duty maintenance such
as chemical storage tanks, corrosive environments, offshore rigs and platforms.
Good outdoor durability and ultra violet light resistance.
Application Procedure
Metal Preparation: All surfaces must be thoroughly cleaned, degreased, free
of rust, oxides or other surface impurities. Recommended pretreatments:
Aluminum – Chemical Conversion Coat
Steel – Phosphate Coat or Acid Etch Primer
Stainless Steel or Titanium – Abrasive Clean
Non-Metal Parts – Has excellent adhesion to plastics, Lexon, Lucite,
Plexiglass, ABS, Polystyrene.
1) Catalyze 3 parts of Urethane Base to 1 part of Urethane Catalyst* by
volume. Add the catalyst* to the base. Allow to stand for 30 minutes before use
(optional).
2) Reduce with Polyurethane Reducer, R-U (uses voc exempt solvents), apx 1
quart per gal of mixed polyurethane/ catalyst* as required.
3) Strain with fine cheesecloth.
Pot life of catalyzed material is 4 to 8 hours at room temperature.
(prolonged by refrigeration)
Never mix catalyzed material with fresh material.
Do not stir polyurethane and catalyst* with the same knife. Avoid cross
contamination.
Spray evenly with air pressure apx 45 to 55 psi. (for texture coat use apx 15
to 25 psi).
