4. Usage
(1) Preparation
Mix the resin and the hardener in the mixing machine. The adhesive should keep a constant temperature (recommended temperature 20-25℃) in the mixing machine to
ensure the applying stability. The mixing ratio should be corrected with the mixing machine before starting application.
Note: Sediment in the resin is normal. Mix the resin uniformly before using.
(2) Substrate Surface Treatment
The substrate surface should be clean and dry, free of grease, dust and other contaminations.
(3) Mixing ratio
Flexibond 8260S: Flexibond 8201=6.5-8.5:1 by weight.
The mixing ratio varies with the different requirements of adhesive consumption and hardness. If the adhesive consumption is low, in order to achieve a high drawing strength, we recommend mixing ratio 6.5:1; if the adhesive consumption is high, in order to achieve a good flexibility, we recommend mixing ratio 8.5:1. For details, please consult Comens technical department.
Stir uniformly component A before using it. Mix the two components strictly according to the ratio. Mix for 1-2 more minutes after the adhesive color is uniform.
(4) Adhesive Coating
The adhesive consumption is 500-1000g/㎡ . The consumption varies with the substrates surface structures and different performance requirements. The mixed adhesive should be used up within its pot life.
(5) Curing and Curing Time
The substrates coated with the adhesive needs to be cured. The turf sheet should be rolled after the adhesive surface tack free. The curing rate varies with the temperature. The lower the temperature is, the longer the curing time it takes. The higher the temperature is, the shorter the curing time it takes. Under the temperature
120℃in the oven, the curing takes 2-5 minutes.
(6) Cleaning
Recommended cleaning solvent: methylene dichloride, ethyl acetate.
5. Packaging
Component A (Resin): 1625kg/drum Component B (Hardener): 250kg/drum
The packaging can be adjusted according to customer’s requirement.
6.Note
(1) The adhesive sealant should be used up once mixed. The remaining sealant cannot be used if viscosity appears too high.
(2) Do not apply the product together with other adhesives. Please enquire to our technicians if you have such a need.
