| General epoxy adhesive |
YGLUE ™211A/BDESCRIPTION: YGLUE™211A/B is solvent free, liquid epoxy, which is fast curable at room temperature(low to 5℃). It always be used in sticking metal, jewelry and crystal, it always do for the same or the different kind of materials. The product after curing has excellent adhesion, high hardness, shockproof, good flexibility, good chemical resistance.
RECOMMEND USAGE: YGLUE™211A/B suit for all need to sticking electrons or other kinds of products are used; Not suitable for the adhere of the flexible or soft outer cover products.
SURFACE PREPARATION: Ensure the surface preparations, and that the surface is clean and dry, free from dust, perfect degreasing. It is best that first chemical treatment, then coating, so can capture best adhesion.

RECOMMEND TECHNIC: SURFACE PREPARATION→BASEBOARD PREHEATING (50-60℃) →GLUE MIXING→PROOFING →VACUUM DEFOAMING→CURING
CLEAN UP: Clean all tools and equipment at the end of each days work with organic solvent.
CLEANNESS & MAINTENANCE: Only use commonly cleaning method, e.g. mull dip in clear water, and do not use grinding cleaning tools. Had better not use organic solvent as detergent.
PACKING & STORAGE: YGLUE™211A/B all act 1kg per tank.2kgs per set. 6 months in an unopened can, kept in cool dry storage. Seal up for keeping after open the cover as early as possible.
NOTE： Ratio must be just. For accelerating at room temperature, can heating baseboard with electric hot plate. Prevent shake, blow, and ensure surface level up. It is best that be forced after cured 12 hours. Curing at room temperature and dampness, the surface easy display fog, suggest curing at heated.
HEALTH & SAFETY：Avoid swallowing. Wear suitable gloves and eye protection. As the YGLUE™211A/B is solvent free, it is relatively non-toxic and it is non-flammable. Spills can be removed by cloth or by using sand to absorb the glue. Once dry the product no longer dissolves in organic solvent. Remove from skin before glue dries.
