Technical questions and solutions for soft touch feeling paint

 Question 1:

Phenomenon:the surface of coating is wet,not dry,

Reason analysis:  1)the dosage of curing agent is not enough

                             2)the dosage of drier is not enough

                             3)solvent contains water

                             4)baking time is not enough 

     Solutions:      1)increase the dosage of curing agent

                           2)increase the dosage of drier

                           3)use PU grade solvent

                           4)prolong baking time in oven

Question 2:

Phenomenon:the coating do not have good adhesion on substrate

Reason analysis:  1)on the substrate there are too much impurites

                             2)the primer is too tough

                             3)the primer is too dry

Solutions:           1)clean the surface of substrate,and paint the primer

                           2)apply suitable primer

                           3)when the primer drying up to 70%, spraying soft touch paint immediately,you don’t have to wait the primer dried completely,

Question 3:

Phenomenon:the coating is not that smooth

Reason analysis:  1)no addition of handfeel additive

                             2)using matting powder of bigger diameter

                             3)the elastic resin is not that soft and smooth

Solutions:           1)add our handfeel additive such as A3,083,087

                            2)using matting powder of smaller diameter, such as OK520

                            3)using elastic resin of good smooth performance such as our Softstar series resin 32#

Question 4:

Phenomenon:the coating is too tough,

Reason analysis:  1)the coating is too tough                                    

Solutions:             1)increase dosage of elastic resin or lower dosage of curing agent

Question 5:

Phenomenon:the pot life of soft touch feeling paint is too short

Reason analysis:  1)too fast drying speed, more dosage of drier

Solutions:           1)lower dosage of drier

                           2)using elastic resin with suitable drying speed.
