Summary of AP-905 is produced by two-component addition reaction crosslinking, curing into a high-performance elastomer; it consists of two parts A, B liquid composition. A group is black or white, B component is white. When the two components in a 1: 1 mix ratio by weight, the mixture of experience curing soft elastomer. Can be cured at room temperature, can also be accelerated cured at a high temperature below 80 ℃. Significant contraction and reaction temperature curing materials no time. After curing the elastomer has good electrical properties, resistance to aging, high and low temperature (-60 ~ 200) ℃, waterproof, good deep curing, and the contacts and the material does not have a corrosive effect on the surrounding environment does not produce pollution; RoHS Compliant instruction and related environmental requirements. By using our special primer to enhance adhesion properties of colloids and materials; suffix indicates the color after curing: W (white), B (black), G (gray), R (red), L (transparent) II Technical characteristics No. Test items AP-905 (black, gray, white) Appearance (after curing) solid white solid black solid gray 2 mixed viscosity (mPa · s,) 1000 ~ 1600 1200 ~ 2600 2000 ~ 3500 3 Hardness ( Shore A) 40 ~ 50 50 ~ 60 50 ~ 65 4 used in a proportion (A︰B) 1︰1 5 operating time (min, room temperature) <1206 Full curing time (hr, room temperature) 4 ~ 87 Tear Strength ( KN / m) ≥2.0 8 Tensile strength (MPa) ≥1.0 9 Elongation (%) ≥70 10 Compressive strength (kv / mm) 15 11 Volume resistivity (Ω · cm) 1.0 × 1012 12 Thermal conductivity ( w / m · k) 0.6 ~ 0.8 13 flammability rating V0 Third, the use for general electronic components, power modules and printed circuit board potting protection, and waterproof, resistant to high voltage; and a variety of automotive electrical and electronic appliances potting. The use of methods 1. Weigh: Accurate weighing A, group B (pre-weighing the A, B groups were respectively stir evenly, so there is filler settling and then uniformly dispersed in glue); A constituent and B components should be 1: 1 (by weight) ratio and mixed thoroughly. 2. mixed plastic: the B component is added to Part A stirring, mixing, rubber showed a uniform color. Mixed complete manual methods available, can also be used for automatic mixing and dispensing equipment, manual methods mixed with glue to note that a one-time can not be too much, so as not to reduce mobility difficulty late Glue; 3. degassing: the mixed plastic material set vacuum degassing cabinet with entrained air is removed by vacuum; 4. Casting: After the bubble gum off irrigation to the parts to complete the potting operation (front parts of the surface and the mixing container potting kept clean and dry). 5. Curing: The finished parts potting room temperature or heat cured. At room temperature, colloid mixed with time, the viscosity will gradually increase in viscosity within 40 - 60 minutes will be doubled. V. Notes some material ﹑ ﹑ chemical curing agents and plasticizers can inhibit the cure gel. These materials should be noted: A organic tin and tin-containing silicone rubber; D phosphorous or phosphorous-containing materials;; E B ﹑ polysulfide sulfur compounds or sulfur articles; C ﹑ amine or ammonia-containing urethane rubber goods acidic items (acids); F flux residues; if used before the glue after suspected to contain these substances, recommend a sample trial validation, and then mass production. VI, packaging and storage Packing: 40kg / set (A component B component 20kg + 20kg), product is non-toxic and non-dangerous goods, according to general chemical handling, transportation, storage in a cool (room temperature), dry place, shelf life of 12 months.
