HILAM GP - 100
 
HILAM GP-100 +GP-100H system is two component solvent based polyurethane adhesive systems for general lamination of various films, aluminum foil and paper etc. HILAM GP-100 especially for metalized film lamination by excellent adhesion and good bond strength. It is very suitable for food packaging and non aggressive dry product packaging.

Application Areas
HILAM GP-100 + GP-100H is recommended for laminating substrates for flexible packaging for snacks ,foods ,bread ,coffee ,chocolate ,milk ,meat, cheese and non aggressive dry Products, Packaging etc Laminate substrates used are BOPP, PET, Metalized Film, CPP, LLDPE, Aluminum Foil, Paper etc
 
Application Guide
Coating Method
HILAM adhesive is applied on all dry laminating machines with gravure roll coating or cylinder coating
 
Drying Temperature
With Dry chamber temperature or drying web temperature of 65 o C and combining with Nip roll temperature of 650C-950C are recommended to completely remove the solvent carrier.
Ensure complete removal of solvent. To prevent retention, drying condition has to be adjusting to substrate, application weight and machine speed.
High laminating temperatures together with high line pressure of calendar improve the bond strength and optimal appearance of laminated properties.
 
Coating weight /Deposit weight
For normal applications the dry adhesive coating weight may range from 2-2.5 gsm on the film or foil combination and the end use of the laminates. However for the specific application like in ticker/porous substrate (such as paper and board), higher coating weight of dry adhesive is recommended.
If the coating weight of the adhesive which is coated on films is too small, that the appearance will not be 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 etc.
 
Substrate
Unprinted or Lightly webs
Heavily printed webs or thicker substrate
Recommended dry Adhesive Deposit
2 – 2.5 gsm
up to 3-3.5 gsm
 
Speed Line
Fastest Line speed 60 - 150 m/min.

Aging Time
48 hours at approx. 50oC - 60oC.

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 laminating of storage at room temperature.

Use recommendation

The bonding strength makes a difference according to each film, even the sources materials of film are same, but their bonding strength can be quite different and beside additives and slip agents on polyethylene and polypropylene film, aggressive ingredients, printing inks, corona treatment and film coating are significant importance for the final performance properties.
All the polyolefin films must be treated prior to lamination and treated surface to be used for lamination .The recommended level is 38 ̴ 40dynes/cm 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 GP-100 + GP-100H before using it in production, to check its suitability for each and every end use requirement.

Pot Life
The pot Life of mixed adhesive is 12-14 hours depending on the temperature and the quantity of the mixture.

Cleaning
The application system of the equipment should be cleaned with solvent after every operation. Special care should be taken to avoid adhesives drying and curing in the cells of the gravure application cylinder.

Storage /Caution & Safety
The adhesive and hardener must not be stored in direct sunlight or flame or spark source and stored in the place where 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 material, material safety data sheet to be followed.

Standard packing
HILAM GP-100 is available in 200 kg Barrel packing and in 50 kg barrel and GP -100H in 24 Kgs pail & 6 kg cans.
