Waterproof Electronic Sealing Strip Adhesive
Adhesion to the substrate is a very important property of the sealant in actual use. The sealant must have good adhesion to the actual substrate before it can be used. An easy way to check the adhesion is to clean and dry the substrate with a suitable solvent or detergent, apply the sealant on it, and after the sealant has cured (about 3-5 days), peel off the sealant by hand. Observe the adhesion. There is also the elongation of the sealant. The elongation is the elastic performance of the sealant after it is completely cured, and it is also one of the mechanical properties. It refers to the percentage of the ratio between the total elongation of the material when it is stretched and the original length. A sealant with good elasticity will have a greater elongation.
Product Description
1. The product picture is as above
2. Product features and applications
ST-3615 is a low viscosity, low hardness, heat-cured liquid silicone rubber. With excellent climate aging resistance and other characteristics, It can be used in-60~ + 200℃, with good chemical stability and non-toxic. Before curing, this product is a light blue transparent liquid. Through the F FA DA detection and certification, it can be solidified into a low shrinkage elastomer at a certain temperature. After curing, it has high strength, high toughness, high transparency and other characteristics, which can be an overall deep solidification. Can be used in the clothing, fabric, silicone products industry.

Notes: The above performance data are based in 25±2 ℃ and relative humidity 50 ± 5%.
4. How to Use
1) Cleaning: Clean the equipment and adhesive products before glue.
2) Curing: Fully mix the A and B components in a ratio of 1: 1 (weight ratio / or volume ratio). (Static mixing is recommended Mix, without defoaming). The A/B component must be fully mixed, and if undermixed, it may cause incomplete curing or weakened physical performance. The allowable operation time of the product is related to the ambient temperature, and the higher the ambient temperature, the shorter the allowable operation time. Permissible operating time ≥ 1.5 hours / 25℃.
3) If air bubbles are found in the curing process, the curing temperature of the front section can be reduced and then the time is extended, and the temperature can be increased after the basic solidification, which can effectively solve the bubble problem.
4) This product is easy to be poisoned by molecular compounds containing P(phosphorus), S(sulfur), N(nitrogen) elements, and the curing agent in condensed silicone rubber can also affect curing, pay attention to cleaning to prevent impurities from mixing. The above chemicals may affect the curing of the product. Please conduct a compatibility test before use.
5. Storage and Transportation
1) This product should be sealed and stored in a cool, dry and ventilated place (5 ° C ~ 25 ° C) to prevent rain and sun exposure.
2) In a normal storage environment, the storage period is 12 months.
3) After the products shall be opened, they shall be exhausted as soon as possible. The unused products shall be sealed in a safe place.
4) If the machine glue injection machine is used, it is recommended to clean the glue injection machine daily.
5) This product is non-dangerous goods and can be stored and transported by general chemicals.
6. Packing
This product A, B glue is packed in 2600ml, 20kg or 200kg /plastic drum.
