the studio and the use of utensils must be kept clean, otherwise it will affect the quality of glue and bonding effect, especially oil, dust will affect the transparency and adhesion of the drops of glue. Indoor humidity should not be too large, as far as possible to maintain ventilation or exhaust fans, personnel walk around as far as possible to wear slippers or shoe covers, indoor air is too cloudy, can sprinkle a small amount of water on the ground.

1, the studio and the use of utensils must be kept clean, otherwise it will affect the quality of glue and bonding effect, especially oil, dust will affect the transparency and adhesion of the drops of glue. Indoor humidity should not be too large, as far as possible to maintain ventilation or exhaust fans, personnel walk around as far as possible to wear slippers or shoe covers, indoor air is too cloudy, can sprinkle a small amount of water on the ground.

2, glue drop workshop as far as possible to maintain room temperature of 25 degrees, the temperature of the glue can be used and curing time has a great impact, in addition, open air conditioning, pay attention to the air outlet water mist directly on the surface of the glue layer, chemical reaction with agent B composition, white fog, oil, granular phenomenon.

3, drip glue working table as smooth as possible, so as not to appear glue flow, dew glue, drop is not in place, drop uneven situation, you can use balance instrument, balance ruler to debug.

4, the temperature has a great influence on its curing, the temperature rises, the curing time is accelerated, as the temperature decreases, the curing time is extended, the temperature is too high, can not be used, will damage the nature of the glue, can not be restored. Cured products can not be baked for a long time under severe temperature conditions, generally can not be higher than 110 degrees, anti-aging test experiment, placed at about 65 degrees for a few hours, observation.

5. Glue must be sealed and stored in a cool and ventilated place to avoid high temperature or sunlight. The yellowing is largely due to the fact that glue is not resistant to UV rays in the sun, or beyond a certain light irradiation time.

6, glue must be mixed strictly according to the weight ratio, if the B agent is too much, it will accelerate the solidification of the glue hard, even can not dry; If the component of agent B is too small, the curing speed slows down so that the glue is soft, or even can not dry.

7. The general shelf life of this kind of glue chemical is 6-8 months. If any component is found to be precipitated within the shelf life, please re-stir evenly before use or replacement.

8, if the drop of glue products after the edge phenomenon, first with acetone or toluene wipe surface dirt and oil, or first spray oil and then drop glue, such glue (including PU) is composed of oily material, add color paste powder mixing, to add oily material components, otherwise there will be stratification.

9. When the glue ratio is dropped, the mixing should not be too fast and too fierce. It should be evenly mixed along the wall slowly.

10, pour out the unused glue, it is strictly prohibited to pour back into the original VAT packaging, the impurities brought in will make the whole barrel of glue scrap. Glue AB at 200g each time the best, too much reaction will concentrate more energy, can be used for a shorter time, poor liquidity.
