HILAM HP -300
 
HILAM SL-300 + SL-300H solvent less adhesive system based on polyurethane is a two component, its typical application for general lamination of various films and aluminum foil, and it especially provides eco friendly performance, non toxic, has good adhesion and suitable for packaging snack, coffee, chocolate, milk cheese, meat and other non aggressive dry products.
And it also provides excellent performance for extrusion lamination /anchor coating.

Application Guide
Coating Method: HILAM 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 40°C —45°C, and the temperature transferring roll is about 45°C— 50°C, the adhesive temperature must be checked with a thermometer to ensure the temperature of adhesive also remains 40°C — 45°C.
High Laminating temperatures together with high line pressure of calander 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 not be clear and it will look like bubble, floating, roll mark & the bonding strength will be poor and similarly if the coating weight is too-much, it will look like blur tunneling, wrinkle, shrinkage etc.
 
Speed Line
Fastest line speed 150-250 m/min

Ageing Condition
48 hours at approx 50°-60°C at aging room


Curing Time
The la minatecan be processed, rewound and slit after 1-2 days, for triplexlaminatesis possible 24 hoursafter duplex production. Good lamination bond are achieved within 7-8 daysafter lamination of storage at room temperature.
 
Use Recommendation
Precise web tension control together with a suitable winding avoids de-laminationsas well astelescoping and curling effects.
Please use after complete mixing of adhesive& hardener.
Should not be reuse left over mixed adhesive.
Avoid contamination of alcoholand 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 toobserve safety precautions of roller coating from damage.
 
Use Recommendation
The bonding strength makes a difference according to each films, even the source materials& films are same, but their bonding strength can be quite different and beside additives and slip agents on polyethyleneand polypropylene films, aggressive ingredients, printing inks, corona treatment & film coating are 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 wettabilitylevel.
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 i 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 flame or spark source and stored in cool thy and well ventilated area 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.
