AG1050A/AG1050B Double-Component Solvent Polyurethane Adhesive

(Alcohol based and low-residual)

1. Description

AG1050A/B is a kind of dry laminating double-component alcohol solvent polyurethane adhesive, widely used in laminating of various treated film like BOPP PET PA PE CPP PVDC etc .

2. Technical Specification

3. features:

High initial bonding strength , outstanding transparency of the laminated film

AG1050A/B is not easy to create the residue with oil ink and films, then get more safety package.

Suitable for middle and high-speed dry laminating machine.

The packaging films laminated by AG1050A/B is specially suitable for food and medicine package which have a strict stipulation of the sanitation safety, and suitable for the products which require the low residue of the solvent.

It complied with US FDA 21CFR175.105.

4. Mix Ratio By Weight

Solvent is isopropyl, modified methanol, ethanol, purification shall be up to 95%. Ethanol is the recommended solvent.

Operation Instruction:

Standard mix ratio: AG1050A to AG1050B=8:1, in case of high humidity circumstance, please add more hardener, please choose the proportion according to operation environment.

Dilution: add the solvent to the main agent, stir fully , then add the hardener and stir fully again .

Working concentration: 20-35%, best working concentration is 30%.

The coating weight: the coated weight on dry base is generally 1.5-3.0g/, but should be changed by the type of film and the weight of the filler.

Evaporation: For evaporating the solvent completely, the drying tunnels should generate enough air speed , air volume and suitable temperature, temperature shall be controlled around 55-85. If the drying device is three sections structure. The temperature from entrance to exit should be 55-65,65-75, 75-85 C.degree respectively.

It is recommended to raise the pressure and temperature as possible, but do it without damaging the film.The laminating rollers temperature : shall be set to 50-80 generally. If the laminated plastic films are sensitive to temperature, the temperature shall be set to 50-60, and 60-70 for other films.

Curing: The products laminated will be cured at 40-50 C.degree for over 12 hours before cutting and making bags.

5. Package

Main agent is 16kg/barrel. Hardener is 2kg/barrel.

6. Storage

AG1050A/B is flammable material, Please keep it in cool and dry place, its quality guarantee is 12 months. Please use up quickly as possible after open the package.

7. Performance Comparison

Example: Films for laminating (OPP30ink / CPP30); printed area: 60%; operate by Machine made by Fuji; Laminating speed: 120m/min; Curing 12hours at 45; base on liquid chromatography Shimadzu.
