Typical uses

Special primer for elastic base surface

Proportion

Component A: Component B= 3:2

Component A: 18KG/bucket Component B: 12KG/bucket

Storage conditions

1.The storage temperature should be 5-35ºC.
2.Under normal storage and transportation conditions, the storage period is not less than 6 months from the date of production.
3.Store in a cool, ventilated environment, avoid direct sunlight, prohibit close to fire sources, and prevent collisions.

Precautions

1.The pre-coated substrate needs to be completely clean, the surface should be dry, dense, free of stains. If there are obvious damage to the interface and cracks, it needs to be repaired in advance. Before using the product, make sure to air-grind the surface or use vacuum to remove dust on the surface.

2.Can be used at a low temperature of -10°C. If used in a low temperature environment, please put the paint bucket in an air-conditioned room for >24 hours.

3.Ensure the raw materials are accurately and evenly mixed, use and pour out how much, and quickly close the lid of the bucket. The used paint must not be poured back into the original bucket. The poured paint must be used up within 1 hour.

4.The paint viscosity adjusted according to the needs of the product before leaving the factory. The construction personnel cannot continue to add the thinner without permission. If needs adjusted as the viscosity changes due to environmental or temperature reasons, call the supplier and add it after obtaining guidance & approval.

Product features

1.Simple to construct, brushing, rolling, spraying can be used.

2.Fast cure, high adhesion on elastic base surface without sagging.
