Method of use
1. metal surface degreasing,derusting,sandblasting,passivation or oxidation treatment, put aside natural air drying or drying in an oven
2. HT-109 and HT-109C according to the ratio of 100:2 mixing evenly, then adds HT109B according to the ratio of 100:5-6 mixing. When in use, adding ethyl acetate or butyl acetate as diluent according to requirements, the dose must be controlled within the mixed solution of 20%.
3. The screen printed material is naturally dried (dry) into the oven curing, curing conditions: 230 ℃ for 50 min.
Caution:
1. Mixing sequence should be strictly in accordance with the above steps, otherwise it will affect the bonding strength of fluorine rubber and metal.
2. screen printing must be dry completely before into the oven, or screen printing adhesive strip will foam, deformation.
