1. Features:
1, the product, A, B component packaging, are colorless and transparent liquid, can be produced under the dark period of preservation.
2, the silicon - oxygen (Si-O) bond-based chain, and therefore can not easily be decomposed by UV light and ozone. Musou key exists, at a high temperature (or radiation) does not break the molecular bond can be -. 50 ℃ ~ 200 ℃ within the scope of transfer Long-term use. After 300 ℃ after seven days of intensive testing colloid do not crack, do not harden.
3, the gel was colorless and transparent gel after curing the body, the 260 ℃ reflow, on the PPA and the adhesion of metal to a certain extent.
4, has excellent electrical insulation properties and good sealing.
5, suitable for production of automatic or manual dispensing patch Large, fluorescent plastic, the top mold package, low power LED (1210,5050, etc)
Second, the recommended process: different packaging process, proposed a different ratio, it will get better results.
1, by weight ratio of A: B = 1:1 ratio with plastic, stirring for 10 minutes.
2, vacuum deaeration for 20 minutes.
3, before gluing, please stand at 150 ℃ for 60 minutes or more than warm tide. Stent not re-absorb moisture as soon as possible before sealing compound.
4, the first 110 ℃ bake 1 hour and then heated to 150 ℃ 160 ℃ bake 3 hours or bake for 2 hours, sub-curing can be an effective solution to improve the yield bubble problem.
Third, pay attention
Production should be computed with the amount of glue, the operating time must be spent within the plastic. With plastic when the mixing must be uniform, otherwise it will not completely cure affect product performance. This product is a silicone rubber products, the use of the process and what substances should be taken to avoid contact with:
1, organic tin compounds and other organic metal compounds.
2, containing organic tin compounds silicone rubber.
3, sulfur, and more sulfur compounds, polysulfone, and other sulfur-containing materials.
4, amine, urethane or other materials containing amines.
5, unsaturated hydrocarbon plasticizers.
