Optically Transparent Epoxy Glues
For Electronic Industry
Are intended for sticking elements of optoelectronic devices [assembly of indicators, matrix emitters, optocouples etc.], and also potting [encapsulation] of the electronic circuits of the surface and closed installation [reading devices, photoreceivers of the big area, condensers, etc.]. Provide good moisture protection, high optical and dielectric properties of devices, operating stability under conditions of temperature extremes, impacts and vibrations.
For Optical Industry
Are intended for sticking optical elements among themselves and bonding them in settings, potting [gluing] ends of fiber optic cables in hard and flexible endoscopes, manufacturing component basis of FOLC [optical forks, sockets etc.], and also small diameter lenses. Glues have good spreading, high light transmission in UV, visual and IR fields of a spectrum; in a cured state are resistant to moisture, pressure, temperature, and other aggressive factors. The high hardness in a polymerized state allows realizing high quality of a polish.
For Jewelry Industry
Are intended for bonding insertions from semi-precious stones, glasses, amber, decorative plastics in products from metals and alloys, and also impregnation stone raw materials with the purpose of its hardening. Provide the improved masking of a gluing layer [at the request of the customer glues can be colorless or toned in necessary color], good cohesion of join, and also prevention of damages [cracking etc.] fragile stones at machining and while in service.
Are intended for sticking of glass, porcelain, transparent plastics, metal, tree, covering atmosphere and waterproof coats [for example, in badges etc.], manufacturing of fibreglasses. Have good moistening, high adhesion. In a cured state glues are not toxic, are fireproof, are resistant to activity of spirit, petrol, weak acids and alkalis, and also to mechanical and temperature actions [from -60 up to +140ºС].
Base Compositions & Modifications
The pot life of glues PEO-10K, PEO-110K, PEO-115K,
PEO-13K, PEO-113K and PEO-33KE ranges after mixing components not less than 1
hour, glues PEO-10K-0,5E, PEO-10KE and PEO-15KE - not less than 2 hours, and
glues PEO-90K, PEO-40K and PEO-28K - 1 day at room temperature.
The typical optical and physical-mechanical characteristics of cured glue bonds: spectral region of transparence 300-2200 nm, transmittance of layer by thickness 0,1mm 98-100%, index of refraction nD = 1,55 - 1,59, ultimate strength at a tension 35-55 MPa, relative tensile elongation 4 - 6 %, water absorption 0,1 - 0,3 %.
