Product introduction Yoho composite resin 528 is a new type of solvent-based polyurethane adhesive, which can be directly coated with 50% of the original adhesive, truly realizing high solid and low adhesive, effectively reducing VOCs emissions, saving composite costs, reducing energy consumption and solvent residues in composite processes. This product does not contain polyether components, and has little effect on the friction coefficient of PE film; At the same time, in the case of no need to update the equipment, the initial adhesive degree and curing conditions of the dry replicating machine are basically the same as that of the traditional ordinary polyurethane adhesive, and the use is more convenient.
Yoho composite resin 528 has the characteristics of low viscosity, good transparency, good leveling, good wettability, good solvent release, fast curing speed, etc. It can be applied to the composite between film (BOPP, BOPET, BOPA, CPP, PE) and aluminized film (VMCPP, VMPET), aluminum foil (AL) and paper, and can be widely used in soft packaging composite of drugs, food, industrial products, etc. 528 can be boiled (100℃, 30 minutes).
Instructions for use
1, diluent: dilute the water content of the solvent should not exceed 500ppm (5 parts per thousand), alcohol content should not exceed 200ppm (2 parts per thousand). When solvent quality cannot be determined
Must pass the test, confirm the quality before use.
2, the ratio: the recommended ratio of this product is 5:1(528A:528B), under special circumstances after testing, the ratio of B components can be adjusted appropriately.
3, mixing method: First add the appropriate amount of solvent to component A, stir at A uniform speed clockwise, and then add component B to the diluted component A solution, stir at a uniform speed clockwise for 3-5 minutes.
4, the requirements for composite substrates: composite substrates need to be surface treated. BOPP, CPP, PE requirements up to 38 dyne; BOPET reached 50 dynes and BOPA reached 52 dynes. AL must ensure that the oil removal is clean, and the oil pollution level is class A; The non-double-sided BOPET and BOPA can not be combined on both sides, otherwise the peeling strength of the non-corona surface can not be guaranteed.

7, coating: the levelling of Unienergy composite resin 528 is very excellent, the use of 170 mesh or more of the cable roller can meet most of the product structure of the composite, the wet glue transfer rate of the cable roller is recommended at 4.5 g ~7 g; You can use the original glue on the glue, you can also adjust different working concentrations according to different material structures and printing films, regardless of which working concentration is applied
Cloth, it is necessary to test the amount of wet glue transfer of the cable roller many times to accurately control the amount of glue on the dry base.
8, the amount of glue on the dry base: Unienergy composite resin 528 adopts the company's proprietary self-crosslinking technology, can achieve a stable peel strength with a low amount of glue, it is recommended that the general dry base
The glue content is 1.4 ~ 2.8 grams. In actual operation, the appropriate amount of glue on the dry base can be determined by testing according to the type of composite substrate, printing area and ink performance.
9, drying: Ulidonergy composite resin 528 has excellent solvent discharge performance, drying process setting can be referred to ordinary solvent-based polyurethane adhesive.
10, curing: at about 45℃ curing 24 ~ 48 hours and fully cooled after the next process can be processed. Boiling and aluminum foil composite is recommended at 48 ° C ~50° C curing time of 48 hours.
11. Use and storage time: The prepared glue can be used after being stored in a closed container for 6 hours to test the performance of the glue without abnormality, under high temperature and high humidity (temperature >28℃, humidity)
>60%, it is recommended to use within 2 hours. The remaining glue solution that has not been used up on that day shall be sealed and stored at low temperature (temperature 0~5℃), and the storage time shall not exceed 12 hours; Before using the remaining glue again, make sure that the quality of the solution has not changed, and add new glue according to the proportion of not more than 10%
12, special note: Unienergy composite resin 528 general composite strength is excellent, large stress, in the composite VMPET or VMCPP may appear different degrees of aluminization transfer phenomenon, need to be tested for suitability, confirm the qualification before mass production.
13, film additives, film pretreatment and coating, printing process, composite industry, as well as the contents of the packaging will have an impact on the final performance of the composite product, before large-scale production, it is recommended to carry out sample testing and related testing to confirm. Our company will provide "Unipower composite resin 528 special friendly tips" according to the market use situation, please refer to it carefully.
