DESCRIPTION: YGLUE™8480A/B is a non-solvent epoxy resin for surface flooring which can cure at low temperature and high-moisture condition, the solidification surface is gloss and can bear the acid and alkali, resist rub and high pressure.

RECOMMEND USAGE:

1. chemical laboratory, electrical factory, office, food products factory, school, cleanser factory;

2. chemical plant, drink factory, brewery, hospital, floor of the weight strength workshop;

3. the sterile room, the meter control the room, the reference room, pharmaceutical manufacturing plant

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.

CHARACTER:

1. Bears the acid and alkali, wear-resisting, bears the chemicals and bears the solvent.

2. Does not have the volatility, the water resistance, the waterproof character and the oil resistance are all good;

3. brittleness, the high degree of hardness, toughness are all good;

4. not moist, does not infiltrate the perspiration;

5. does not aid combust, not the spontaneous combustion, security, healthy, non-toxic, not smelly;

6. dustproof, artistic, does not have the joint point, easy to maintain

RECOMMEND TECHNIC:

1. construction surface renovation, elimination fat, impurity and making the projecture leveling

2. the ground must be hard, smooth, don’t have the phenomenon of loosens

3. the vessel used to stir should be the circle as far as possible, in order to mix completely.

4. before construction , the concave hole and the crack must make up evenly by the putty

5. the perpendicular plane should construct first, in order to avoid pollution horizontal plane

6. if the level paints of the gap surpasses for a week, the surface must have mill rough by the sand, again paint the bottom to increases the adhesion

7. the mixed agitation of the material should use up in the possible period of revolution, also the material must link up continuously completed, in order to avoid the material surface is close to solidification and is unable to flow evenly

8. when spreading the cloth levels, the surface did not allow the visual air bubble, if still had the air bubble, use the hair brush, the hoop, or the trowel to make surface levels before the solidification

9. if the sand grains or the impurity discovered when spreads the cloth, should eliminate immediately.

CLEAN UP: Clean all tools and equipment at the end of each days work with organic solvent.

CLEANNESS & MAINTENANCE: Only use common cleaning method, e.g. mull dip in clear water, and do not use grinding cleaning tools. Had better don’t use organic solvent as detergent.

PACKING & STORAGE: YGLUE™8480A/B all act 25 kilograms 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™8480A/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.
