HT-5791 single component room temperature vulcanized silicone rubber
First, almost described
HT-5791 one component neutral de solidified alcohol, and condensation of moisture in the air emit low molecule induced crosslinking through, and vulcanized elastomers with high performance. The elastomer has the characteristics of anti leakage, moisture proof, waterproof, waterproof, and anti vibration. It is suitable for the majority of metal and nonmetal materials with good adhesion. It can be used in a variety of electronic components, and can be used in the range of -60 for -+220.
Has excellent electrical insulation properties, sealing performance and aging resistance. Fully comply with the requirements of the EU ROHS directive.

Three, typical use:
General purpose: to the metal case of non metallic materials of the elastic bonding, and the adhesive material is non corrosive, all kinds of water under the instrument of waterproof, moisture resistance, all kinds of electrical sensor elastic bonding.
Sealing the end of the electric heating pipe, chemical equipment, mirror, electrical equipment, small household electrical appliances, power supply, LED module, optical instrument, etc..
Coating: the insulation of various electronic components, semiconductor equipment and electrical equipment, moisture and shock, protective effect.
Four, the use of methods and precautions:
Clean the surface: glued or coated components surface clean, remove dust, dirt, rust etc.;
Sizing: the cleaned components placed smoothly, unscrew the hose cap, mounted on the supporting plastic nose, with a blade in on a spit according to the required size openings, glue crowded to glue the parts can be. This glue is absorbing the moisture in the air from the surface to the internal curing, layer maximum cured thickness 2 ~ 4mm, such as more than 4 mm in depth, the best is the two Tu. The product table dry time of about 5 minutes, after 24 hours to complete the full curing, the lower the winter temperature, curing time will be extended.
Note: the product should be used as soon as possible after the Kaifeng, such as the failure to use immediately tighten the cap, seal. When used again, if the seal has a little crust, the removal can be, without affecting the normal use. Glue in the process of storage, mouth also may be a small amount of curing phenomenon, will be cleared after normal use, does not affect the performance of the products.
Five, packaging, preservation and transportation
With aluminum skin tube or plastic tube packaging, specifications have 50ml tube, 100ml tubes and tube 300mlPE, also can be other custom packaging according to customer requirement;
This product should be stored in dry cool place (26 degrees Celsius) of the place; the product shelf life of 6 months from the date of making.
To avoid the impact of extrusion or hard scratch, this product is a non dangerous goods, can be used as general chemical transportation.
