How to Use Citrine™ CA-625 Silicone rubber primer


Surface treatment: wipe off any debris and dirt using a lint-free towel, cloth, or dry air. Using alcohol or mild solvents, clean the substrate to remove oils.

Preparation:

Using a weight scale, pour component A into a container and note the weight. Add an equivalent amount of component B into the container. Mix the contents thoroughly and evenly. The silicone primer is now ready for application.


Application, Drying, and Curing:

CAL-625 Silicone rubber primer for aluminum is applied on the substrate by brushing, dipping, spraying, or screen printing.

Once applied, use heat to dry and cure the bonded silicone aluminum products. Bake the bonded products at 110–130 °C (230–300F) for 15-20 minutes.

Make sure you bond the silicone rubber with the substrate as soon as possible after the glue (primer) is applied. This will give the best results. Full vulcanization should be done on the same day. To avoid product contamination, make sure the silicone primer mixture does not come into contact with high temperatures, high humidity, or heavy metals.

Lastly, use high-temperature or hot-air vulcanization to bond and mold the uncured liquid silicone rubber (LSR) to the substrate.


Store the silicone rubber primers in a cool, dry place away from heat and open flames. The silicone primer solvents are flammable and should always be stored tightly in a closed container after use. Store mixed silicone primers in a separate closed container.

We recommend using all Citrine silicone primers in well ventilated rooms to prevent long-term inhalation or long-term skin effects. PPE and good manufacturing practices are highly recommended while using the primers.

Due to moisture, silicone primers can become cloudy. Cloudiness does not affect adhesion.

During the vulcanization process, it is important to avoid products that will cause these primers to have poor adhesion. These products include:

Products containing heavy metals such as Sn, Pb, Hg, Sb, Bi, As, organic compounds, e.g., N, P, S,
and organic compounds containing unsaturated groups such as ethynyl groups.

Lastly, before high volume production, test your substrate for compatibility
