PRODUCT INFORMATION DATA SHEETS POR 15 PUTTY A clean, dry surface is a necessary pre-requisite for proper adhesive bonding; and adhesive will either stick to a surface where a bond is desired or to whatever film may be on that surface. Rarely can a structural adhesive penetrate through surface contaminants to provide an optimum bond when the surface is not clean. Porous materials are simple to bond to, provided they are dry. Surfaces should be sanded until clean and free of dust. Non-porous surfaces such as metal and plastic should be degreased, dried and roughened by sanding, sandblasting, or chemical etching. Etched or sandblasted surfaces should be covered within a few hours of treatment to prevent contamination. Handlers should wear clean cotton gloves to prevent body oils from contaminating the clean surfaces. For best results, follow the procedures listed below where practical. ALUMINIUM AND ALUMINIUM ALLOYS - De-grease with trichlorothylene.
- Dip in the following solution for 10 minutes:
3 parts sodium dichromate 10 parts 96% sulphuric acid 20 parts water (Be careful to dissolve sodium dichromate in water, then add sulphuric acid slowly) - Rinse in ambient water.
- Rinse in hot 50-60°C (150-170°F) distilled water.
COPPER,BRASS AND OTHER COPPER ALLOYS - De-grease with trichloroethylene.
- Dip in a solution consisting of 6 parts ferric chloride, 30 parts concentrated nitric acid and 200 parts water (dissolve the ferric chloride in the water, add the nitric acid slowly). Or dip in a 25% aqueous solution of ammonium persulphate for 1-2 minutes.
- Rinse with distilled water and dry.
FERROUS ALLOYS OTHER THAN STAINLESS - De-grease with trichloroethylene.
- Sandblast, sand (100 grit) or etch in 15% aqueous hydrochloric acid (equal parts concentrated muriatic acid and water) for 10 minutes. Etched surface should be rinsed immediately and dried with hot air. Freshly sandblasted or etched steel begins to rust immediately; therefore adhesive should be applied as soon as the surface has been prepared.
NYLON,ABS,POLYCARBONATE,ACRYLATE,EPOXIES,ZINC,LEAD,NICKEL,TIN - De-grease with acetone, methy ethyl ketone or trichloroethylene.
- Mechanically abrade (sandblast, scrape, rub).
- De-grease.
STAINLESS STEEL,CHROMIUM De-grease with trichloroethylene. Etch with concentrated hydrochloric or muriatic acid for 15 minutes at room temperature or with a solution consisting of 90 parts water, 96% sulphuric acid, and 0.2 parts Nacconol NR(National Aniline) for 10 minutes at 50°C(150°F) followed by 10 minutes at room temperature in a solution consisting of 90 parts water, 15 parts 70% nitric acid and 2 parts 48% hydrofluric acid. STONE, CERAMICS, GLASS - De-grease with trichloroethylane.
- Wire brush (stone), sandblast
INSTRUCTIONS FOR USING POR15 PUTTY FOR MAXIMUM STRENGTH AND MINIMUM SET-TIME… THE A AND B HALVES MUST BE MIXED THOROUGHLY! - Use equal parts and A and B
- Hands should be clean and free from oil.
- Tear, roll, fold and kneed the halves together vigorously.
- Mix for at least 2 minutes for a walnut sized piece. Mix for at least 15 minutes for the whole pound.
- The warmer the temperature, the faster the POR15 Putty will cure. At 24°C(75°F) the cure time is 60 minutes. Reducing the temperature by 2.5°C(5°F) will double the cure time. Use a hot air gun to shorten the time.
- Thoroughly clean and roughen surfaces (see reverse side of page)
- Cut off equal amounts of A & B and tightly rewrap exposed end with tin foil or plastic wrap. Exposed end may discolour over a period of time-if it does, remove it before reusing.
- Mix A & B together thoroughly until it has a smooth colour with no striations.
- Apply and let cure until hard. To smooth putty into place, moisten hands with water.
- After applying, wash hand thoroughly with soap and water.
- Avoid prolonged contact with skin. Wash hand before eating or smoking.
