(1).Apply a thin uniform coating to the bonding surface using the minimum amount that will fully coat the surface, allow cnhybond 944 primer to dry thoroughly before applying tape. This is usually accomplished in 5 minutes at room temperature, Be sure the primed surface remains free from contaminants prior to applying the tape. Porous surfaces may require 2 application of CNHYBOND 944 primer for uniform coverage and good adhesion..
(2). Allow first application of primer to dry before applying the second coat, CNHYBOND primer 944 may be applied with brush or swab, It can also be applied with a pressurized flow gun, knurled roller or other similar type of application equipment
(3).Drying Time
Drying time generally depends on the temperature, humidity,thickness of coating.
Normal drying time:1 minute-1 hour
The best drying time:10-30minutes(temperature:23℃, moisture65%)
Keep coating surface clean while operating
(4).Stick double sided tapes
Stick double sided tapes to the surface of coating, and press it strongly.
