1. Overview:
FW401//FK-100 is a high-performance water-based, cost-effective two-component reactive polyurethane dry-type composite adhesive, suitable for It is used for the lamination of light packaging composite materials such as OPP, CPP, PE, PET, NY, VMPET, VMCPP and other substrates.
Second, Product features:
1. This product does not contain free TDI components, does not contain organic solvents, and is a healthy and environmentally friendly adhesive developed by the state.
2. It has good adhesion to various film substrates, high transparency, good leveling, and meets the requirements of light packaging;
3. It is suitable for composite flexible packaging materials with high transparency;
4. It has good leveling and wetting properties, suitable for medium-speed coating.

Four.Reference ratio:
Generally, FW401/FK-100=100/5-15, and the ratio is preferably 100/10 . For different substrates, customers can adjust the ratio according to the actual situation.
V.Dilution solvent and requirements:
First add water to the main agent, stir well, then add the curing agent, and stir well.
6. Working concentration: The recommended concentration is 20-25%.
Seven, the scope of application: General dry compounding
VIII. Coating amount: 1.5-3.0g/m2 (dry basis), (depending on the post-processing, use and quality requirements of the film structure)
Compound drying tunnel temperature: It is necessary to pay attention to have sufficient air volume, air speed and temperature, and the temperature can be selected between 55℃ and 95℃. When the drying system is divided into three sections, the temperature from the membrane inlet to the outlet is controlled between 55-75°C, 65-85°C, and 75-95°C.
Nine, Aging temperature: 50±5℃
10. Aging time: 24-48 hours.
TenI.Packaging: Main agent: 20kg/barrel curing agent: 2kg (can be made according to user requirements packaging)
TenTwoStorage: Water-based products should be sealed and stored at 20°C with a lid, in a dry environment, and avoid being placed in the open air; storage and transportation need to be separated Heat, moisture, freezing, sealed storage period of half a year.
Thirteen, Notes:
1. Composite substrates such as PE, CPP, BOPP, PET, PA and other films need surface treatment, and their surface tension: PE, BOPP, CPP should reach 38 dynes or more, PET should reach 50 dynes or more, PA reaches 52 dynes or more.
2. The type and content of film additives have an impact on the bonding strength of the composite film, and should be selected before use. In particular, the content of slip agent in the film is very important and must be strictly controlled.
3. The substrate to be bonded should be clean and dry, free of dust and oil, and must be corona treated, and the surface tension should not be lower than 38 dynes.
4. The type of film additives, glue concentration, the depth of the anilox roll, and the number of lines have an impact on the bonding strength of the composite film, which should be selected before use.
5. In the process of compounding, attention should be paid to checking and controlling the viscosity of the adhesive; there should be enough coating amount and sufficient curing.
6.After opening the package, it must be used up within a short period of time. Do not mix this product with other adhesives.
7. The formulated adhesiveshould be used up within 8 hours as much as possible. Ifit is found that the viscosity of the adhesive is obviously increased or appears cloudy, it should be stopped.
