PROFILE
YD-5208 is a cycloaliphatic amine modified epoxy hardener, colorless transparent liquid, free of APEO and formaldehyde, with excellent resistance to yellowing. It is suitable for use in zipper coating, fishing rod adhesive, composite materials and other fields.
ADVANTAGES
1.Good resistance to yellowing and excellent adhesion.
2.Hardness and strength increase quickly in the early stage.
3.Good chemical resistance.
APPLICATIONS
Used for zipper coating, adhesive, heavy-duty anti-corrosion and other industrial coatings.
STORAGE
It should be sealed in the original packaging container and placed in a dry location between 0-40 ℃(temperature should not be lower than 0 ℃), and should not be placed in sunlight.
