3, the use of instructions
3.1 the substrate surface should be clean and dry. It can be heated to remove the moisture on the surface of the substrate; using naphtha, methyl ethyl ketoxime (MEK) or other suitable solvents to clean the substrate surface should not be use to the substrate in a dissolution or corrosion of the solvent, should not use the residual solvent.
3.2 in accordance with the recommended mix proportion - A:B = 1:2 (weight ratio), accurate weighing to clean glass containers, and fully mixed with the use of high speed mixing equipment, high speed mixing heat generated may make the temperature rise, thereby reducing the use of time.
3.3 the 10mmhg vacuum extrusion bubble. Before dispensing package material extrusion bubble. According to the need in the post allocation can also increase the bubble removal procedures.
3.4 to ensure the operability of the compound, A, B mix, please run out in 120 minutes.
3.5 curing conditions:
Heat to 90 degrees, bake for about 90 minutes, and then heat to 150 degrees, 180 minutes of baking.
4, product packaging
4.1 this product is divided into A, B double group of packaging.
4.2 the product is made of plastic or glass bottle packaging, specifications for the 500 grams per bottle packaging, a set of 1500 grams.
4.3 this product packaging marked name, brand name, batch number, weight, manufacturer, date of manufacture etc..
5, storage quality
5.1 this product please keep in the room temperature, avoids the sunlight, the ventilation is dry.
5.2 not used up the product should be re sealed to save, it is recommended to put into the glass drying box.
5.3 the preservation period of the product is 6 months from the date of making the home.
6, note
6.1 it is forbidden to mix B A into the bottle, because of the small amount of B glue can cause the phenomenon of A glue and knot!
6.2: certain materials, chemical agents, curing agents, and plasticizer can inhibit the curing of elastomeric materials:
1, organic tin and other organic metal compounds
2, sulfur, polysulfide, polysulfones or other sulfur containing items
3, amine, polyurethane rubber or containing ammonia
4, sub phosphorus or phosphorus containing items
5, some flux residues
If there is doubt about whether a certain type of substrate or material will inhibit the curing, it is s ested that a compatibility test should be done to test the suitability of a specific application. If there is a doubt that the substrate and the interface between the elastomer material is not compatible, it will inhibit the curing.
The above performance data is the typical data measured in the laboratory environment of the temperature 25, humidity 70%, only for the use of the reference, and can not guarantee the full data in a specific environment, please customers in the use of experimental data as the standard.
