[Instructions]This product belongs to the additive type, so it can only be added during use.
The PH value of the adhesive should not be lower than 7, otherwise, too fast cross-linking will affect the film-forming effect.
Add amount (according to binder solid content 1 ~ 3% adjustment).
With the rapid development of environment-friendly printing technology, higher requirements have been put forward for water resistance, cohesive strength and dry and wet resistance of high-grade environment-friendly printing.
Environmental protection printing crosslinking agent FK with printing adhesive [carboxyl butyl benzene latex, styrene acrylic emulsion, water-based acrylic emulsion, waterborne polyurethane dispersion 】 in the hydrophilic group of crosslinking reaction, the adhesive formed through crosslinking modification of linear structure of the original mesh three-dimensional structure, raise the water resistance of printing coating, bond strength and wet strength, resistant to chemicals and so on, reduce the deformation of printing coating, significantly improve the printing coating performance.
Environmentally friendly printing crosslinker FK is miscible with water and many organic solvents and can react in dry conditions.The amount of environment-friendly printing cross-linking agent FK is usually 1%-3% of the solid content of printing binder, which can be cured at room temperature or baked and cured by heating.The cross-linked coating can significantly improve the water resistance, chemical resistance, dry and wet friction resistance, surface viscosity, and improve the adhesion on special fabrics, etc.
Green printing cross-linking agent FK features
Environmentally friendly printing crosslinking agent FK can react with the carboxyl group of printing adhesive, making the hydrophilic group in the adhesive change from hydrophilic to hydrophobic through cross-linking, and forming a stable cross-linking at low temperature, thus improving the drying rate.
Environmentally friendly printing cross-linking agent FK, as a water-resistant cross-linking agent for printing adhesive, has the characteristics of fast curing cross-linking, formaldehyde free, low consumption and good adaptability. Its clothing products meet ROHS and REACH standards and can be exported to THE European Union and Japan.
Environmentally friendly printing cross-linking agent FK is used in the paint of printing adhesives. The cross-linking curing is rapid, and the finished product has good water-resistant performance without requiring long storage time or multi-stage drying, which enables printed garments to obtain excellent comprehensive performance in wet friction resistance, dry grinding resistance and water-resistant.In large-scale industrial production, this product has the following characteristics:
1: Improve the speed, increase production capacity: improve the drying speed of adhesive, that is, improve the speed, greatly increase the production capacity per unit
2. Reduce comprehensive energy consumption: Reduce drying temperature, that is, reduce energy consumption and improve economic benefits
3: Improve the quality of the garment: it can react with the adhesive, provide high strength water resistance effect, can react quickly with carboxyl groups, can be quickly finished after getting off the machine, can greatly improve the wet friction and dry friction of the finished product, and water resistance.
4: Higher environmental requirements: no free formaldehyde, belongs to environmental protection products.
5: It is more suitable for the washing of stoneware enzyme of cowboy pulp.
