AUTOMOTIVE MB-155 Multi Purpose Panel Adhesive Metal Owner’s Manual

AUTOMOTIVE MB-155 Multi-Purpose Panel Adhesive Metal

Product Information

MAXI-BOND 155 is a two-component, room temperature curing, black-colored, odorless, thixotropic polyurethane adhesive specially designed for structural bonding of a wide range of materials.

It is suitable for bonding materials such as thermosetting and thermoplastic materials, steel, aluminum, concrete, wood, and glass.

The adhesive is available in bi-component cartridges (side by side) or in several sizes of drums for different application needs.

Specifications:

• Type: Two-component polyurethane adhesive
• Curing: Room temperature
• Color: Black
• Odor: Odorless
• Application: Structural bonding of thermosetting and thermoplastic materials, steel, aluminum, concrete, wood, and glass

Product Usage Instructions

1. Preparation: Ensure surfaces are clean, dry, and free from contaminants.
2. Mixing: Dispense equal parts of Component A and Component B into a clean container and mix thoroughly.
3. Application: Apply the mixed adhesive to one surface and join the parts together within the working time.
4. Curing: Allow the adhesive to cure at room temperature as per the manufacturer’s recommendations.

PROCESSING

The strength and durability of bonded joints depend 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 isopropanol. 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 mechanical abrasion to remove paint from the surfaces (where necessary) and to increase the strength and resistance of the adhesion. Let dry the pre-treated area before applying the adhesive.

PRODUCT APPLICATION

MAXI-BOND 155 is available in bi-component cartridges (side by side), or in several sizes drums. Anyway, blending should be made through static mixer composed by a minimum of 16 elements. A lower number of components doesn’t allow a complete mixing. A higher number of components would increase speed of the chemical reaction of hardening. Static mixers are disposable.
Bi-component cartridges can be used through manual applicators or specifics pneumatic tools, depending on capacity and cartridge shape.

For process and in continuative applications, automatic dosing systems for low-viscosity materials can be used. Base on specific needs MAXI-BOND 155 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 be at least 0.5 mm thick. The components have to be assembled before the adhesive starts curing and sealed with a steady pressure all over the gluing area.

REACTION MECHANISM

The speed of the hardening 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 increase. 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 40°C.

TECHNICAL CHARACTERISTICS OF CURED PRODUCT

The below properties have been measured through standard samples tests, made bonding by overlapping samples of different materials of dimensions 100 × 20 × 20 mm with an adhesion area of 20 × 20 mm. The values, obtained with standard methods on typical lots, are exclusively provided as technical information, and not as product specification.
In any case, it will be up to the user to test the product for a specific situation and then give his final approval.

PRODUCT STORAGE
MAXI-BOND 155 has a shelf life of 12 months from the initial production as long as it is stored in a cool and dry place, between +20 °C and +30 °C. Expiry date is indicated on the label. 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 CAUTIONS

MAXI-BOND products are generally quite harmless to handle provided that certain precautions are normally taken when handling chemicals.
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.
