PROCESSING: The strength and durability of bonded joints are dependant on proper pre-treatment of the surfaces to be bonded. At the very least, joint surfaces should be cleaned with a good degreasing agent in order to remove all traces of dust, dirt, oil and grease. Pre-treatment of thermoplastics materials such as PVC, polycarbonate, polypropylene, PMMA, etc., can be made using a mixture of light ethers or with iso-propanol. Use of strong solvents is not recommended due to the risk of damage to the plastic surface. Pre-treatment of other surfaces can be made using acetone or trichloroethylene. Petrol or other solvents should never be used. Where possible, carry out a mechanically abrading to remove paint from the surfaces (where necessary) and to increase strength and holding gluing. Let dry the pre-treated area before applying the adhesive.
PRODUCT APPLICATION: AD8001 is available in bi-component cartridge (side by side or coaxial) in 50ml or 178ml. Blending should be made through static mixer composed of at least16 elements. A lower number of components doesnt allow for complete mixing. A higher number of components would increase speed of the chemical reaction of hardening. Static mixer are for a unique use only. Despite the good chemical thixotropy of the product, bi-components syringes can be easily used without help of mechanical tools. Bi-components cartridges can be used through manual applicators or specifics pneumatic tools, based on capacity and cartridge shape.

For process and in continuative applications, automatic dosage system for low viscosity materials can be used. Based on specific needs Adhesive Dispensing Ltd technical service is available to offer advice for the correct machinery to use with specific requirements. The mixture must be applied directly from the mixer on the pre-treated dry surface. The optimal layer of adhesive that will guarantee the highest resistance for the joint should have at least 0.2 mm of thickness. The components have to be assembled within the first minute of extrusion of the adhesive and sealed with a steady pressure over the gluing area.
REACTION MECHANISM: The speed of the harden reaction is mainly influenced by two factors: the application temperature and the application thickness. Being the reaction exothermic, the speed decreases as the thickness and temperature application decreases. Even if in smaller measure, the substrate influences the speed of reaction. Materials with a high coefficient of thermal conductivity will tend to slow down the reaction. The maximal temperature of the reaction will be reached in 5 mm application thickness and is always lower than 90C.

PRODUCT STORAGE: AD8001 has a shelf life of 12 months from the initial production as long as it is stored in a cool and dry place, between +10C and 25C. Expiry date is indicated on the label. The cartridges have to be kept in a sealed plastic bag and protected from light and heating sources inside the original packaging. Once opened, the cartridges will last until the expiry date (as long as the above conditions are met) leaving the last mixer used onto the cartridge.
PRODUCT HANDLING CAUTION: Adhesive Dispensing Ltd products are generally quite harmless to handle provided that certain precautions are normally taken when handling chemicals are observed. The uncured materials must not be allowed to come into contact with foodstuffs or food utensils, and measures should be taken to prevent the uncured materials from coming in contact with the skin, since people with particularly sensitive skin may be affected. The wearing of impervious rubber or plastic gloves will normally be necessary; likewise the use of eye protection.

The skin should be thoroughly cleaned at the end of each working period by washing with soap and warm water. The use of SOLVENTS has to be avoided. Disposable paper should be used to dry the skin. Adequate ventilation of the working area is recommended. These precautions are described in greater detail in the Safety Data Sheet for the individual products and should be referred to for further information.
NOTE: The information, and, in particular, the recommendations relating to the application and end-use of our products, are given in good faith based on Adhesive Dispensing Ltd current knowledge and experience of the products when properly stored, handled and applied under normal conditions. We cannot assume responsibility for the results obtained by others over whose methods we have no control. It is the users responsibility to determine suitability for the users purpose of any production method mentioned herein and to adopt such precautions as may be advisable for the protection of property and of persons against any hazards that may be involved in the handling and use thereof.
Adhesive Dispensing Ltd specifically disclaims all warranties expressed or implied, including warranties of merchantability or fitness for a particular purpose, arising from sale or use of our products.
