User Guide - Hardnose Paints
Like many other POR-15 coatings, Hardnose Paint is a moisture-cured coating,which means it is strengthened by exposure to moisture. It won't crack, chip,peel, or yellow, and is flexible as well. Hardnose Paint is available in these beautiful colors:
Important: After mixing, wait one hour before using to permit molecules of both parts to interlock. Note: If Hardnose Paint is to be put directly onto bare aluminum or other reactive metals like zinc, copper, or brass, use POR-15's AP 120 METAL PREP on the bare metal surface first. This will insure perfect adhesion of Hardnose Paint to those metals. APPLICATION PROCEDURES Your Your HARDNOSE PAINT purchase consists of two items: 1) a round paint can (either a pint, quart, gallon, or 5 gallon) filled with Part A, which is the basic paint formulation; and 2) a smaller screw-top cap with Part B, our Hardener/Activator. Mix the two products together. After the coating is thoroughly mixed, begin applying immediately. Warning: Your can of Hardener/Activator is filled to the very brim and is sealed with a screw-cap and a metal insert underneath the cap. Remove the insert carefully. Cover with a paper towel while prying it off to avoid accidental spillage or splash.Your Hardener-Activator is very sensitive to moisture and humidity,so try to open it in a dry area. Keep it tightiy capped when not in use. PARTIAL MIXES You may mix partial quantities of Hardnose Paint for small jobs, and you may use any measuring device you happen to have around (coffee scoop measuring spoons, cups, etc.). All you have to do is follow this formula:
POT LIFE
APPLICATION Apply a minimum of 2 full coats for automotive or industrial use and a minimum of 3 full coats for marine use. You may apply Hardnose Paint with any type of brush you prefer, and it can also be rolled on. It will flow out immediately,eliminating brush marks. First, lay down a covering coat and be careful to avoid runs. A second coat may be applied when to first coat is dry to the touch, usually 15-20 minutes later at 68º F (20º C). In temperatures below 64º, drying times will be extended and consequently runs may be more likely, so to minimize this problem in colder temperature, small items may be warmed with a heat gun, or perhaps air temperature could be raised for larger items. Hardnose Paint may be sprayed using 30 - 35 lbs pressure. Thin only with Xylene, if required. POR-15 Solvent or laquer thinner may be used for cleanup. You can thin Hardnose Paint up to 20% with Xylene. NOTE: When applying a 2nd or 3rd coat, surface tension between coats may increase and you can add more Xylene to reduce the coating surface tension, thus allowing it to drop and flow out. SPECIAL NOTE : Hardnose Paint will not reach maximum hardness nor will it perform as specified until it has cured a minimum of four (4) days at an average temperature of no less than 64º (18º C). Do not put alloy wheels, engine parts, or other stress-affected parts into use before the four (4) day cure. Elevated temperatures will not speed up the cure. If the surface to be coated is dirty or greasy, clean with Marine Clean , mixed at a ratio of 1 part Marine Clean to 15 parts warm or hot water. Use a sponge or soft cloth, wash the surface, then rinse well with water. If surface is relatively clean, just wipe it first with Xylene before preping it with AP 120. NOTE: If the surface is clean, water will fil across it rather than bead up. Next, spray on AP 120 and leave it on for two minutes, NOT LONGER, then wash off with water and permit to dry thoroughly. ALWAYS WEAR PROTECTIVE GLOVES. NEW OR OLD UNPOLISHED ALUMINUM OR STAINLESS STEEL: The object is to remove the oxides from the surface. You can treat the surface the same way as for polished aluminum, but for these metals you may wish to eliminate the polishing compound step. It is vital to wash away the Marine Clean residues afterward. because if this isn't done thoroughly, some residues may be trapped under the coating, causing bubbling at a later date. After washing, let air dry thoroughly. LABORATORY TEST RESULTS Because the main concerns for a clear topcoat is length of life and resistance to various atmospheric conditions, we have subjected Hardnose Paint to the following tests:
In ASTM B-117 testing and ASTM D-1654 testing, Hardnose Paint was tested along with four well-kncwn rust preventive primers: ZINC PHOSPHATE PRIMER, BARIUM METABORATE PRIMER, ZINC CHROMATE PRIMER,and ZINC RICH PRIMER. Test durations were set at 500 hours, 1000 hours, and 1500 hours in a condensing humidity 5% salt spray solution at 950F (350C) Products that withstand 500 hours in this test are considered to be good anti-corrosive coatings.
The TABER ABRASION TEST was conducted using a Taber Abrasion machine with CS-17 wheels and 1250 grams of pressure. After 500 cycles Hardnose Paint lost 20 mg. of weight while a standard two-component epoxy lost 23 mg. Hardness was measured by a SWARD Hardness tester seven days after both products were applied to identical panels. The results are as follows:
