Q

Coating Orange Peel

A

The essence of orange peel texture is insufficient leveling time of the coating liquid — the wet film is locked by curing before the surface tension completes flattening. The core of the solution is "extending the open time": use a high-boiling-point solvent to delay surface curing, add a levelin...

Q

Incomplete Curing

A

The essence of incomplete curing is that the crosslinking reaction has not reached the designed conversion rate. The core of the solution is the precise matching of the three elements "temperature + time + formulation": ensure the curing temperature and time are within the recommended window of t...
