LOCTITE UK 8303-B60 - 24kg (2C polyurethane adhesive, up to 80 °C)
Product description:
LOCTITE UK 8303 B60 / LOCTITE UK 5400 is a solvent-free two-component adhesive, based on polyurethane. The resinpart (component A) contains organic compounds with hydroxyl groups, the hardener (component B) is based onisocyanates. By mixing both components in a mix ratio of 6 : 1 a hard elastic product is formed through chemical reaction. After curing the product exhibits no measurable change in volume. As natural raw materials (from different cultivation areas) are used a variation in color between different batches is possible. Further information about the product: biuro@woronko-kleje.pl
Steps to achieve the best adhesive results:
Pretreatment
The substrate should be clean, dry, free of dust, oil, grease and other contaminants. The usage of suitable primers on metal surfaces can improve the adhesion and/or the long-term bond stability. The surface of plastic materials should be cleaned, so as to remove any kind of release agents present on the substrate surface. An improvement of the adhesion can be achieved by grinding or sandblasting the surface.
Application
Adhesive components can be mixed manually by using an electric hand mixer, or by using a two component dispendingsystem. The adhesive is only to be used within a limited time (pot life). After this time the mixture gels up and is not suitablefor use. Therefore only the amount that can be applied within the time of pot life should be mixed. The pot life depends onthe quantity and temperature of the mixed batch. With larger quantities and an increase in temperature of the mixed batch.With larger quantities and an increase in temperature, the pot life decreases. Lower temperatures extend the the pot life.Adhesive components should not come into contact with moisture during storage or application. Contact with moisture generates foaming of the filler and weakens the bondline. Therefore all packaging should be sealed properly and protected against humidity during storage.
Curing
LOCTITE UK 8303 B60 / LOCTITE UK 5400 can be cured between 15°C and elevated temperatures (up to 60 °C). Thecuring time will be reduced substantially with increasing temperatures. While curing there should be adequate contact pressure (load pile, presses, clamps) and fixtures to hold the joint in place. An adhesive squeeze out along the bond line is a good indication of sufficent adhesive in the joints.
Cleaning
Fresh, uncured material (cleaning application equipment, substrate contamination etc.) can be removed with LOCTITE SF 8040; cured adhesive can only be removed mechanically.
