How to use and precautions

Gel time adjustment: increasing or decreasing the proportion of A/B components can extend or shorten the gel time of the product. When customers use it, make fine adjustments as needed; as the ratio of A/B increases, risks may occur. The phenomenon of oil or incomplete curing; as the ratio of A/B decreases, the rubber will become harder, the elasticity will decrease, or it will be corrosive to the plastic kit.

Mixing: Mix the rubber thoroughly and evenly by hand or machine so that the rubber has a uniform color. When using the manual glue filling process, be careful not to add too much glue at one time, otherwise the fluidity will be reduced later and it will be difficult to fill the glue.

Potting: The device surface and mixing container should be kept clean and dry before potting.

Curing: Do not completely seal or heat the potted device before the small molecular substances generated during the curing process are completely released. If complete sealing is required, the product must be exposed to the air after use. It can be carried out for more than 7 days. seal.

This product is non-dangerous, but please keep it out of your mouth or eyes.

Store in a cool, dry place away from rain and sunlight. The shelf life is six months under unopened conditions at 26°C.
