RTV silicone sealant(adhesive), industrial silicone sealant

silicone sealant for industry such as electronic, LED, LCD and so on
OPT315W
two-component silicone pouring sealant
Product information
OPT315W
is
a kind of two-component

condensation type room temperature curing silicone sealing adhesive. Ethanol which is absorbed during curing is non-corrosion to PC PP, ABS, PVC and copper. It has good adhesion to most of electronic fittings (except for PP, PE).


Product features
1. Potting and protection of outdoor LED screen and electronic equipment module
2. Rubber after curing with elasticity and shock resistance
3. Heat resistance, moisture-proof and freeze resistance which) prolong the life of electronic fittings.
4. Ethanol is absorbed and non-corrosion to equipments during the process of curing
5. Primer is unnecessary with strong adhesive to PC(Polycarbonate),Epoxy material.
6. IP65 water proof grade.
Use
Potting of electronic equipment and module

Using method and note
1. Stirring the A adhesive by hand or with machine before using and stir the B adhesive in an airproof container. Repack the left adhesive.
2. Ensure the material can be adhesive before use.
3. Mixed the adhesive in weight ratio: A:B = 10:1. Generally, more B component requires longer curing time.
4. Mix the adhesive in the airproof container for 5 min, deaeration under 700mmHg.

5. It will be cured with shorter time in higher temperature but heated-curing is not suggested.

Storage and transportation
1. The product should be stored under cool, dry condition and the shelf-life can be 9 months under 25°C.
2. These products don’t belong to dangerous goods, so they can be transported as normal chemicals.
3. Seal the mixture to avoid Leakage.
4. Products past deadline must be confirmed before use.
