چسب لمینیت حلالی (hp)
APSHPSBL polyurethane adhesives are designed for large dry composite machine. They have many advantages including high solid content, low viscosity product, good liquidity, transparency, better membranous, good initial bonding strength, less residual solvents, high compound fastness, and so on. it can be applicable to general compound bags, vacuum bags, 102℃ boiled bags and the cooking foil materials of high, medium and low speed compound machine of dry composite, then processed into various

Instruction
- Use ratio: main agent : curing agent : solvent ۵:۱:۸~۱۰
- Adhesives dilution method and working concentration
Dilution method: put ethylacetate in to the main agent, mix and then add curing agent fully mixing
Working concentration: Ordinary adhesives in the 25% ~30%
- When main agent mixed with curing agent, please run out in six hours. When the temperature belows 5℃, the mixture could be extended to 12 hours. However, when the mixture appeared turbid or high viscosity, it could not used.
- Substrate surface shuold clean and dry, and no dust pollution. Plastic film surface should be treated by the corona to make its surface tension above 40 dyne/cm. It can obtain the ideal bonding effect.
- Coating quantity: It depends on the product usage, dry adhesives coating quantity generally was 3~4g/m2. The material containing aluminum foil should be cooked at 121℃. Coating quantity should be 4~5g/m2.
- Complex: The temperature of the composite films usually controls in 50~100℃. Transparent film compound is easily influenced by heat, the complex temperature is 50~60℃. The complex temperature for aluminum film is 80~100℃, and others are 70~80℃. Humidity generally controls in 50%~70%, high humidity would greatly influence the adhesive performance.
- Dry: In order to make the solvent in the film coated with adhesive evaporation, the film should be through the drying devices. The air flow, speed and the temperature should be controled.
- Aging: The composite products after compund treatment should be send to the aging room and they can attain the bonding strength. The temperature was 50~60℃. The aging time is more than 24 hours. For cooking productsm, the aging time is more than 48 hours.
User Guide (notice for use)
- Polyurethane adhesives belong to flammable solid. No poen flames.
- If open the package of the products, please run out in a short time. Curing agent easily absorbs moisture and goes bad. The products should be pay attention to dry, sunscreen and sealed storage.
- Polyurethane adhesives should avoid mixing with solvent containing lively hydrogen, such as water, alcohol and amine.
- The storage period of main agent is one year. It must be stored in the shadows. If it expires but not go bad, it still can continue to use.
- اگر جوهر چاپ یا تامین کننده تغییر کرد بایستی تست مجدد انجام گیرد
