APPLICATION GUIDE :
- Coating Method :
HILAM SL-300 solvent less adhesive is applied on special laminating machines with Roller Coating method. - Adhesive Temperature :
The thermostatic temperature control on the metering rollers should be set to 40oC - 45oC, and the temperature transferring roll is about 45oC - 50oC, the adhesive temperature must be checked with a thermometer to ensure the temperature of adhesive also remains 40oC - 45oC.
High Laminating temperatures together with high line pressure of calendar improve the bond strength and optimal appearance of laminated properties. - Coating Weight :
For normal applications the coating weight may range from 1.0-3.0 gsm, depending on the film or foil combination and the end use of the laminates.
For printed laminates the weight has to be adjusted accordingly.
If the coating weight of the adhesive which is coated on films is too small, the appearance will be not clear as like bubble, floating, roll mark, the bonding strength is not enough either and just the opposite if the coating weight is too-much, that the blur tunneling, wrinkle, shrinkage and etc. - Speed Line :
Fastest line speed 150-250 m/min - Ageing Condition :
48 hours at approx 50OC - 60OC at aging room - Curing Time :
The laminate can be processed rewound and slit after 1-2 days, for triplex laminates is possible 24 hours after duplex production. Good lamination bond are achieved within 7-12 days after lamination of storage at room temperature. - Use Recommendation :
Precise web tension control together with a suitable winding avoids delaminations as well as telescoping and curling etc.
Please use after completed mixing of adhesive & hardener. Should not reuse leftover mixed adhesive. Avoid contamination of alcohol and water from adhesive. - Pot Life :
The pot life of mixed adhesive is more than one hour. - Cleaning :
When the lamination machine stops for more than 30mins, the coating unit has to be cleaned with solvent to observe safety precautions of roller coating from damage. - Use Recommendation :
The bonding strength makes a difference according to each film, even the source materials of films are same, but their bonding strength can be quite different and beside additives and slip agents on polyethylene and polypropylene films, aggressive ingredients, printing inks, corona treatment & film coating are of significant importance for the final performance properties.
All the polyolefin films must be treated prior to lamination and treated surface to used lamination. The recommended treatment level is 38 ~ 40 dynes per centimeter to achieve minimum required surface wet-ability level.
Since the ingredients in films and inks may interfere with the good performance of this adhesive, customers are strongly recommended to carefully test HILAM SL-300 + HILAM SL-300H before using it in production, to check its suitability for each & every end use requirement. - Storage /Caution &Safety :
The adhesive and hardener must not be stored in direct sunlight or near flame or spark source and stored in cool, dry and well ventilated and keep stored in the original unopened and undamaged container. Opened containers of the material have to be closed immediately and the material should be consumed within a short period. Avoid contact with skin & eyes.
Safety regulations with regard to handling of materials as well as material safety data sheets have to be followed. - Standard Packing :
HILAM SL-300 is available in 200 Kgs/Barrel or 50 Kgs/Barrel and HILAM SL-300H in 24 Kgs/Pail or 6 Kgs/Can.
