Etch – For optimum results, metal parts should be immersed in a chromic acid bath solution consisting of:Sodium dichromate – 4 parts by weightSulfuric acid – 10 parts by weightWater – 30 parts by weightThe solution should be held at a temperature of 160°F (71°C), and the parts left immersed for 5 to 7 minutes. Rinse – remove metal parts from etching bath and rinse in clean cold water (de-ionized water is recommended). If thoroughly clean, metal surfaces so treated will hold a thin film of water. Dry – To accelerate drying, items to be bonded can be placed in an air-circulating oven. ALTERNATE PROCEDUREDegrease, scour and dry – Often etching as outlined above is not practical. The metal surfaces may be cleaned by degreasing as noted above, scouring with an alkaline cleanser followed by rinsing and drying. Degrease and dry – Degrease the surface as noted above, sand or sandblast the surface lightly but thoroughly. Rinse with acetone or Methyl Ethyl Ketone (MEK), and dry.GLASSDegrease – With MEK as above, or with a strong boiling solution of a good grade household detergent. Etch – For optimum results, degreasing can be followed by the chromic acid bath outlined above. WOODSand – Bonding surfaces should be sanded lightly, but thoroughly to remove all external contamination. Clean – Carefully remove all dust, or particles of wood from sanded areas. A stiff and clean brush or compressed air can be used. PLASTIC (see Flame Treating below)Clean – Remove all dirt, oil, or other surfaces contaminated with detergent soap or degreasing solvent and water, followed by thorough rinsing and drying. A solvent that does not have a detrimental effect may also be used. Sand – Surfaces to be bonded should be sanded lightly, but thoroughly to remove surface sheen. Clean – Carefully remove all dust or particles of plastic from the sanded area. A clean brush, lint-free cloth, or compressed air may be used. The quality of adhesion of any coating or adhesive application is dependent on how well the surface is prepared.The resin system must be able to properly ‘wet-out’ the surface to form a continuous film. A surface demonstrating poor wettability prevents the liquid resin from forming a cohesive bond. Improper surface wetting yields poor adhesion and will delaminate during use. Wetting is the ability of a liquid to interfaces or wet-out a solid surface; its dynamics is expressed as surface tension. A surface that demonstrates low surface tension, such as waxed surface, oily surface or slick plastics like Teflon will prevent the liquid resin to wet-out and cause poor adhesion. Testing For Surface To Yield Structural Bond AdhesionTesting And Preparing Surface Before Applying Epoxy Coating Or Adhesive. – YouTubeVideo will open in a new window Using the eBay App? Paste link into a browser window:Flame Treating Of Plastic To Improve Adhesion. Obtaining adequate bond strength when bonding plastic-to-plastic substrates or plastic to dissimilar substrates is often a challenge for epoxy bonding.In general plastic surfaces demonstrates poor ‘wettability’ or the ability of a liquid to form a continuous film, must be treated before application.These types of substrates or are called LSE or Low Surface Energy substrates. In general, most thermoplastic surfaces fall into this category. Teflon or its generic name PTFE and other polyethylene derivatives such as HDPE, LDPE, UHMW and olefinic-based plastics demonstrate poor liquid wettability due to its low surface energy. To create a viable bondable surface condition for these types of plastics, it must be surface treated by creating a superficial oxidized surface to increase its dynamic surface tension. Various types of physical treatment can be used to increase the surface energy of plastics, mostly through oxidation of the superficial layer. Flame treatment is the most widely used and cost-effective pre-treatment for polyethylene (HDPE, LDPE, UHMW) and polyolefin-based plastics prior to polymer bonding or printing. The resulting change of the surface by creating an oxidized layer onto the substrate greatly improves the ability of liquids wet-out the surface thus creating a strong adhesive bond between the surface and the coating. A Flame Treating process consists of exposing the surface to a suitable oxidizing flame for a period in the range 0.2 to 3.0 seconds. This treatment brings about a change to the polymer surface that increases its surface energy allowing fluids to effectively wet-out the surface and permits a strong adhesive molecular and mechanical bond. Flame Treating Using A Commercially Available Propane Torch Adjust the propane torch so that a low oxygen burning flame is achieved and pass over the area to be treated several times until a slight haze is noticed on the surface of the substrate. A Dyne pen is used to view the improve surface wetting of the untreated and flame treated UHMW plastic. Flame Treating the plastic substrate will make adhesion possible and create a strong bond.Flame Treated Surface Ideal For Bonding Load Testing For Tensile Shear Strength of the Adhesion Types of mechanical load and stress points Joint and Bonding And Design Suggestions To Make This Resin System To An Opaque Color Add 3% To 5% Of Our Max Epoxy Pigment Paste.MAX COLOR KIT https://www.ebay.com/itm/311946633043 Adding Color With MAX Color Pigment Concentrates IMPORTANT NOTICEYour purchase constitutes the acceptance of this disclaimer.
