Usage

    The bonding substrate preparation:all the surface of the adhesive material should be clean and dry .with anhydrous ethanol, isopropanol acetone and methyl ethyl ketone to be coated component surface dust,oil scrub clean.
    In order to obtain the best bonding results we can use the GC-04 silicone rubber primer.will be the surface of the adhesive material with a solvent wash(with pledget dipped in solvent scrub, scrub finished with dry pledget scrub clean the surface of te solvents of the glass. Scrub cycles to dry pledget without any pollution prevail),parking after 5 minutes, convinced the solvent completely volatile, the surface of the material processed with primer (primer with a cotton swab dipped in swab dipped into the excess primer squeezed out,and then cover. Brushing primer the surface of the adhesive material should coating uniformity, eliminate the uncoated surface occurs),after drying,the surface of the adhesive material to obtain a thin layer of primer tackifying layer.
A method of bonding 
    GD-883 a small amount evenly applied to the adhesive surface, then the adhesive paste together,must be time to make bubbles in the adhesive layer applied some pressure placed on the 23 to 30℃ , humidity ≥60% environment 24 hours before moving, the highest adhesive strength after seven days.
    When the rubber is exposed to the air,the surface of the rubber will soon crust so no matter by any means,adhesive materials and construction completed before the rubber surface crust. With a spatula the plastic material on the surface of the adhesive material for the easily gelling. The rubber hand contact with non-sticky time of not more than 15 minutes.
   Excess rubber is very easy to use a noon-polar solvent deaned.
Curing time
    The surface crust of plastic material after the vulcanization of the rubber material has continued to rely on the contact with air,water vapor from outside to inside gradually,at room temperature under a condition of 50% relative humidity,24hours after the vulcanization of the rubber material is a depth of about 3 mm. More than 5mm coating preferably the batch construction methods, that is each blade coating,curing and then continue to the next construction about 3mm. Relative humidity is lower,the curing time is extended accordingly.
    Before handing or packaging adhesive products,convinced,that the adhesive parts will not be affected. Under normal circumstances, at room temperature for 24 hours can be moved,and complete curing takes one week.
