Substrate pretreatment for One-component PU adhesive sealant Primerless Eco-friendly high bonding strength

The surface of the bonded substrate must be clean and dry without dust, oil and water stains. The bonded
substrate should be cleaned and pretreated with detergent or primer. If it is not, it may cause bonding failure. The glue shall be applied and cured according to the construction method, and the safe driving time is related to the ambient temperature and humidity.

Construction
Ambient temperature and humidity have a great impact on the surface drying and curing of glass adhesive. It
is recommended that the construction ambient temperature be 5 ~ 35 ℃, and the humidity be 50 ~ 70% RH. When the temperature is lower than 5 ℃, it is recommended to put the product in an environment of
30-40 ℃ for heating for 1H before use (the heating time cannot exceed 3H)
The construction method can refer to the construction instructions or consult our technicians.

Storage:
Sealed and stored in a low temperature and dry place. It is recommended to store in an environment with a
temperature of 5~25 ℃ and a humidity of ≤ 50% RH.
Storage period: 9 months

Transportation: moisture proof, rain proof, sun proof, high temperature proof, keep away from heat source, handle with care, and do not squeeze or collide.
